Vaccines

Anecdotal reports have linked the vaccines against COVID-19 to the sudden loss of hearing in some people. But a new study has found no evidence for such a connection with any of the three approved shots. 

The analysis of data from the Centers for Disease Control and Prevention’s Vaccine Adverse Event Reporting System (VAERS) found that the incidence of sudden onset hearing loss was not elevated – and might even be a bit lower than expected – in the first few weeks after the injections.

“We’re not finding a signal,” said Eric J. Formeister, MD, a neurotology fellow at the Johns Hopkins University, Baltimore, and the first author of the U.S. study, which appeared Feb. 24 in JAMA Otolaryngology – Head and Neck Surgery.

Dr. Formeister and colleagues undertook the study in response to reports of hearing problems, including hearing loss and tinnitus, that occurred soon after COVID-19 vaccination.

They analyzed reports of sudden hearing loss, experienced within 21 days of vaccination, logged in VAERS. Anyone can report a potential event to the database, which does not require medical documentation in support of the adverse event. To minimize potential misdiagnoses, Dr. Formeister and colleagues reviewed only those reports that indicated that a doctor had diagnosed sudden hearing loss, leaving 555 cases (305 in women; mean age 54 years) between December 2020 and July 2021.

Dividing these reports by the total doses of vaccines administered in the United States during that period yielded an incidence rate of 0.6 cases of sudden hearing loss for every 100,000 people, Dr. Formeister and colleagues reported.

When the researchers divided all cases of hearing loss in the VAERS database (2,170) by the number of people who had received two doses of vaccine, the incidence rate increased to 28 per 100,000 people. For comparison, the authors reported, the incidence of sudden hearing loss within the United States population is between 11 and 77 per 100,000 people, depending on age.

“There was not an increase in cases of sudden [sensorineural] hearing loss associated with COVID-19 vaccination compared to previously published reports before the COVID-19 vaccination era,” study coauthor Elliott D. Kozin, MD, assistant professor of otolaryngology–head and neck surgery at Harvard Medical School, Boston, said in an interview.

Another reassuring sign: If hearing loss were linked to the vaccines, the researchers said, they would expect to see an increase in the number of complaints in lockstep with an increase in the number of doses administered. However, the opposite was true. “[T]he rate of reports per 100,000 doses decreased across the vaccination period, despite large concomitant increases in the absolute number of vaccine doses administered per week,” the researchers reported.

They also looked at case reports of 21 men and women who had experienced sudden hearing loss after having received COVID-19 vaccines, to see if they could discern any clinically relevant signs of people most likely to experience the adverse event. However, the group had a range of preexisting conditions and varying times after receiving a vaccine when their hearing loss occurred, leading Dr. Formeister’s team to conclude that they could find no clear markers of risk.

“When we examined patients across several institutions, there was no obvious pattern. The patient demographics and clinical findings were variable,” Dr. Kozin said. A provisional interpretation of this data, he added, is that no link exists between COVID-19 vaccination and predictable hearing deficits, although the analysis covered a small number of patients.

“Association does not necessarily imply a causal relationship,” said Michael Brenner, MD, FACS, associate professor of otolaryngology–head and neck surgery at the University of Michigan, Ann Arbor. Dr. Brenner, who was not involved in the study, said any hearing loss attributed to the COVID-19 vaccines could have had other causes besides the injections.

But a second study, also published in JAMA Otolaryngology – Head and Neck Surgery on Feb. 24, leaves open the possibility of a link. Researchers in Israel looked for increases in steroid prescriptions used to treat sudden hearing loss as vaccination with the Pfizer version of the shot became widespread in that country. Their conclusion: The vaccine might be associated with a slightly increased risk of sudden hearing loss, although if so, that risk is likely “very small” and the benefits of vaccination “outweigh its potential association” with the side effect.

Dr. Brenner agreed. “The evidence supports [the] clear public health benefit of COVID-19 vaccination, and the scale of those benefits dwarfs associations with hearing, which are of uncertain significance,” he said.

Kia Slade was 7 months pregnant, unvaccinated, and fighting for breath, her oxygen levels plummeting, when her son came into the world last May.

A severe case of COVID-19 pneumonia had left Ms. Slade delirious. When the intensive care team tried to place an oxygen mask on her face, she snatched it away, she recalled. Her baby’s heart rate began to drop.

Ms. Slade’s doctor performed an emergency cesarean section at her bedside in the intensive care unit, delivering baby Tristan 10 weeks early. He weighed just 2 pounds, 14 ounces, about half the size of small full-term baby.

But Ms. Slade wouldn’t meet him until July. She was on a ventilator in a medically-induced coma for 8 weeks, and she developed a serious infection and blood clot while unconscious. It was only after a perilous 2½ months in the hospital, during which her heart stopped twice, that Ms. Slade was vaccinated against COVID-19.

“I wish I had gotten the vaccine earlier,” said Ms. Slade, 42, who remains too sick to return to work as a special education teacher in Baltimore. Doctors “kept pushing me to get vaccinated, but there just wasn’t enough information out there for me to do it.”

A year ago, there was little to no vaccine safety data for pregnant people like Ms. Slade, because they had been excluded from clinical trials run by Pfizer, Moderna, and other vaccine makers.

Lacking data, health experts were unsure and divided about how to advise expectant parents. Although U.S. health officials permitted pregnant people to be vaccinated, the World Health Organization in January 2021 actually discouraged them from doing so; it later reversed that recommendation.

The uncertainty led many women to delay vaccination, and only about two-thirds of the pregnant people who have been tracked by the Centers for Disease Control and Prevention were fully vaccinated as of Feb. 5, 2022, leaving many expectant moms at a high risk of infection and life-threatening complications.

More than 29,000 pregnant people have been hospitalized with COVID-19 and 274 have died, according to the CDC.

“There were surely women who were hospitalized because there wasn’t information available to them,” said Paul A. Offit, MD, director of the Vaccine Education Center at the Children’s Hospital of Philadelphia.

Vaccine developers say that pregnant people – who have special health needs and risks – were excluded from clinical trials to protect them from potential side effects of novel technologies, including the Pfizer and Moderna mRNA vaccines and formulations made with cold viruses, such as the Johnson & Johnson vaccine.

But a KHN analysis also shows that pregnant people were left behind because including them in vaccine studies would have complicated and potentially delayed the delivery of COVID-19 vaccines to the broader population.

A growing number of women’s health researchers and advocates say that excluding pregnant people – and the months-long delay in recommending that they be immunized – helped fuel widespread vaccine hesitancy in this vulnerable group.

“Women and their unborn fetuses are dying of COVID infection,” said Jane Van Dis, MD, an ob.gyn. at the University of Rochester (N.Y.) Medical Center who has treated many patients like Ms. Slade. “Our failure as a society to vaccinate women in pregnancy will be remembered by the children and families who lost their mothers to this disease.”
 

New technology, uncertain risks

At the time COVID-19 vaccines were being developed, scientists had very little experience using mRNA vaccines in pregnant women, said Jacqueline Miller, MD, a senior vice president involved in vaccine research at Moderna.

“When you study anything in pregnant women, you have two patients, the mom and the unborn child,” Dr. Miller said. “Until we had more safety data on the platform, it wasn’t something we wanted to undertake.”

But Dr. Offit noted that vaccines have a strong record of safety in pregnancy and he sees no reason to have excluded pregnant people. None of the vaccines currently in use – including the chickenpox and rubella vaccines, which contain live viruses – have been shown to harm fetuses, he said. Doctors routinely recommend that pregnant people receive pertussis and flu vaccinations.

Dr. Offit, the coinventor of a rotavirus vaccine, said that some concerns about vaccines stem from commercial, not medical, interests. Drug makers don’t want to risk that their product will be blamed for any problems occurring in pregnant people, even if coincidental, he said.

“These companies don’t want bad news,” Dr. Offit said.

In the United States, health officials typically would have told expectant mothers not to take a vaccine that was untested during pregnancy, said Dr. Offit, a member of a committee that advises the Food and Drug Administration on vaccines.

Due to the urgency of the pandemic, health agencies instead permitted pregnant people to make up their own minds about vaccines without recommending them.

Women’s medical associations were also hampered by the lack of data. Neither the American College of Obstetricians and Gynecologists nor the Society for Maternal-Fetal Medicine actively encouraged pregnant people to be vaccinated until July 30, 2021, after the first real-world vaccine studies had been published. The CDC followed suit in August of 2021.

“If we had had this data in the beginning, we would have been able to vaccinate more women,” said Kelli Burroughs, MD, the department chair of obstetrics and gynecology at Memorial Hermann Sugar Land Hospital near Houston.

Yet anti-vaccine groups wasted no time in scaring pregnant people, flooding social media with misinformation about impaired fertility and harm to the fetus.

In the first few months after the COVID-19 vaccines were approved, some doctors were ambivalent about recommending them, and some still advise pregnant patients against vaccination.

An estimated 67% of pregnant people today are fully vaccinated, compared with about 89% of people 65 and older, another high-risk group, and 65% of Americans overall. Vaccination rates are lower among minorities, with 65% of expectant Hispanic mothers and 53% of pregnant African Americans fully vaccinated, according to the CDC.

Vaccination is especially important during pregnancy, because of increased risks of hospitalization, ICU admission, and mechanical ventilation, Dr. Burroughs said. A study released in February from the National Institutes of Health found that pregnant people with a moderate to severe COVID-19 infection also were more likely to have a C-section, deliver preterm, or develop a postpartum hemorrhage.

Black moms such as Ms. Slade were already at higher risk of maternal and infant mortality before the pandemic, because of higher underlying risks, unequal access to health care, and other factors. COVID-19 has magnified those risks, said Dr. Burroughs, who has persuaded reluctant patients by revealing that she had a healthy pregnancy and child after being vaccinated.

Ms. Slade said she has never opposed vaccines and had no hesitation about receiving other vaccines while pregnant. But she said she “just wasn’t comfortable” with COVID-19 shots.

“If there had been data out there saying the COVID shot was safe, and that nothing would happen to my baby and there was no risk of birth defects, I would have taken it,” said Ms. Slade, who has had type 2 diabetes for 12 years.
 

Working at warp speed

Government scientists at the NIH were concerned about the risk of COVID-19 to pregnant people from the very beginning and knew that expectant moms needed vaccines as much or more than anyone else, said Larry Corey, MD, a leader of the COVID-19 Prevention Network, which coordinated COVID-19 vaccine trials for the federal government.

But including pregnant volunteers in the larger vaccine trials could have led to interruptions and delays, Dr. Corey said. Researchers would have had to enroll thousands of pregnant volunteers to achieve statistically robust results that weren’t due to chance, he said.

Pregnancy can bring on a wide range of complications: gestational diabetes, hypertension, anemia, bleeding, blood clots, or problems with the placenta, for example. Up to 20% of people who know they’re pregnant miscarry. Because researchers would have been obliged to investigate any medical problem to make sure it wasn’t caused by one of the COVID-19 vaccines, including pregnant people might have meant having to hit pause on those trials, Dr. Corey said.

With death tolls from the pandemic mounting, “we had a mission to do this as quickly and as thoroughly as possible,” Dr. Corey said. Making COVID-19 vaccines available within a year “saved hundreds of thousands of lives.”

The first data on COVID-19 vaccine safety in pregnancy was published in April of 2021 when the CDC released an analysis of nearly 36,000 vaccinated pregnant people who had enrolled in a registry called V-safe, which allows users to log the dates of their vaccinations and any subsequent symptoms.

Later research showed that COVID-19 vaccines weren’t associated with increased risk of miscarriage or premature delivery.

Brenna Hughes, MD, a maternal-fetal medicine specialist and member of the American College of Obstetricians and Gynecologists’ COVID-19 expert group, agrees that adding pregnant people to large-scale COVID-19 vaccine and drug trials may have been impractical. But researchers could have launched parallel trials of pregnant women, once early studies showed the vaccines were safe in humans, she said.

“Would it have been hard? Everything with COVID is hard,” Dr. Hughes said. “But it would have been feasible.”

The FDA requires that researchers perform additional animal studies – called developmental and reproductive toxicity studies – before testing vaccines in pregnant people. Although these studies are essential, they take 5-6 months, and weren’t completed until late 2020, around the time the first COVID-19 vaccines were authorized for adults, said Emily Erbelding, MD, director of microbiology and infectious diseases at the National Institute of Allergy and Infectious Diseases, part of the NIH.

Pregnancy studies “were an afterthought,” said Irina Burd, MD, director of Johns Hopkins’ Integrated Research Center for Fetal Medicine and a professor of gynecology and obstetrics. “They should have been done sooner.”

The NIH is conducting a study of pregnant and postpartum people who decided on their own to be vaccinated, Dr. Erbelding said. The study is due to be completed by July 2023.

Janssen and Moderna are also conducting studies in pregnant people, both due to be completed in 2024.

Pfizer scientists encountered problems when they initiated a clinical trial, which would have randomly assigned pregnant people to receive either a vaccine or placebo. Once vaccines were widely available, many patients weren’t willing to take a chance on being unvaccinated until after delivery.

Pfizer has stopped recruiting patients and has not said whether it will publicly report any data from the trial.

Dr. Hughes said vaccine developers need to include pregnant people from the very beginning.

“There is this notion of protecting pregnant people from research,” Dr. Hughes said. “But we should be protecting patients through research, not from research.”
 

Recovering physically and emotionally

Ms. Slade still regrets being deprived of time with her children while she fought the disease.

Being on a ventilator kept her from spending those early weeks with her newborn, or from seeing her 9-year-old daughter, Zoe.

Even when Ms. Slade was finally able to see her son, she wasn’t able to tell him she loved him or sing a lullaby, or even talk at all, because of a breathing tube in her throat.

Today, Ms. Slade is a strong advocate of COVID-19 vaccinations, urging her friends and family to get their shots to avoid suffering the way she has.

Ms. Slade had to relearn to walk after being bedridden for weeks. Her many weeks on a ventilator may have contributed to her stomach paralysis, which often causes intense pain, nausea, and even vomiting when she eats or drinks. Ms. Slade weighs 50 pounds less today than before she became pregnant and has resorted to going to the emergency department when the pain is unbearable. “Most days, I’m just miserable,” she said.

Her family suffered as well. Like many babies born prematurely, Tristan, now nearly 9 months old and crawling, receives physical therapy to strengthen his muscles. At 15 pounds, Tristan is largely healthy, although his doctor said he has symptoms of asthma.

Ms. Slade said she would like to attend family counseling with Zoe, who rarely complains and tends to keep her feelings to herself. Ms. Slade said she knows her illness must have been terrifying for her little girl.

“The other day she was talking to me,” Ms. Slade said, “and she said, ‘You know, I almost had to bury you.’ ”

Brenna Hughes, MD, a maternal-fetal medicine specialist and member of the American College of Obstetricians and Gynecologists’ COVID-19 expert group, agrees that adding pregnant people to large-scale COVID-19 vaccine and drug trials may have been impractical. But researchers could have launched parallel trials of pregnant women, once early studies showed the vaccines were safe in humans, she said.

“Would it have been hard? Everything with COVID is hard,” Dr. Hughes said. “But it would have been feasible.”

The FDA requires that researchers perform additional animal studies – called developmental and reproductive toxicity studies – before testing vaccines in pregnant people. Although these studies are essential, they take 5-6 months, and weren’t completed until late 2020, around the time the first COVID-19 vaccines were authorized for adults, said Emily Erbelding, MD, director of microbiology and infectious diseases at the National Institute of Allergy and Infectious Diseases, part of the NIH.

Pregnancy studies “were an afterthought,” said Irina Burd, MD, director of Johns Hopkins’ Integrated Research Center for Fetal Medicine and a professor of gynecology and obstetrics. “They should have been done sooner.”

The NIH is conducting a study of pregnant and postpartum people who decided on their own to be vaccinated, Dr. Erbelding said. The study is due to be completed by July 2023.

Janssen and Moderna are also conducting studies in pregnant people, both due to be completed in 2024.

Pfizer scientists encountered problems when they initiated a clinical trial, which would have randomly assigned pregnant people to receive either a vaccine or placebo. Once vaccines were widely available, many patients weren’t willing to take a chance on being unvaccinated until after delivery.

Pfizer has stopped recruiting patients and has not said whether it will publicly report any data from the trial.

Dr. Hughes said vaccine developers need to include pregnant people from the very beginning.

“There is this notion of protecting pregnant people from research,” Dr. Hughes said. “But we should be protecting patients through research, not from research.”
 

Recovering physically and emotionally

Ms. Slade still regrets being deprived of time with her children while she fought the disease.

Being on a ventilator kept her from spending those early weeks with her newborn, or from seeing her 9-year-old daughter, Zoe.

Even when Ms. Slade was finally able to see her son, she wasn’t able to tell him she loved him or sing a lullaby, or even talk at all, because of a breathing tube in her throat.

Today, Ms. Slade is a strong advocate of COVID-19 vaccinations, urging her friends and family to get their shots to avoid suffering the way she has.

Ms. Slade had to relearn to walk after being bedridden for weeks. Her many weeks on a ventilator may have contributed to her stomach paralysis, which often causes intense pain, nausea, and even vomiting when she eats or drinks. Ms. Slade weighs 50 pounds less today than before she became pregnant and has resorted to going to the emergency department when the pain is unbearable. “Most days, I’m just miserable,” she said.

Her family suffered as well. Like many babies born prematurely, Tristan, now nearly 9 months old and crawling, receives physical therapy to strengthen his muscles. At 15 pounds, Tristan is largely healthy, although his doctor said he has symptoms of asthma.

Ms. Slade said she would like to attend family counseling with Zoe, who rarely complains and tends to keep her feelings to herself. Ms. Slade said she knows her illness must have been terrifying for her little girl.

“The other day she was talking to me,” Ms. Slade said, “and she said, ‘You know, I almost had to bury you.’ ”

KFF is an endowed nonprofit organization providing information on health issues to the nation.

Kia Slade was 7 months pregnant, unvaccinated, and fighting for breath, her oxygen levels plummeting, when her son came into the world last May.

A severe case of COVID-19 pneumonia had left Ms. Slade delirious. When the intensive care team tried to place an oxygen mask on her face, she snatched it away, she recalled. Her baby’s heart rate began to drop.

Ms. Slade’s doctor performed an emergency cesarean section at her bedside in the intensive care unit, delivering baby Tristan 10 weeks early. He weighed just 2 pounds, 14 ounces, about half the size of small full-term baby.

But Ms. Slade wouldn’t meet him until July. She was on a ventilator in a medically-induced coma for 8 weeks, and she developed a serious infection and blood clot while unconscious. It was only after a perilous 2½ months in the hospital, during which her heart stopped twice, that Ms. Slade was vaccinated against COVID-19.

“I wish I had gotten the vaccine earlier,” said Ms. Slade, 42, who remains too sick to return to work as a special education teacher in Baltimore. Doctors “kept pushing me to get vaccinated, but there just wasn’t enough information out there for me to do it.”

A year ago, there was little to no vaccine safety data for pregnant people like Ms. Slade, because they had been excluded from clinical trials run by Pfizer, Moderna, and other vaccine makers.

Lacking data, health experts were unsure and divided about how to advise expectant parents. Although U.S. health officials permitted pregnant people to be vaccinated, the World Health Organization in January 2021 actually discouraged them from doing so; it later reversed that recommendation.

The uncertainty led many women to delay vaccination, and only about two-thirds of the pregnant people who have been tracked by the Centers for Disease Control and Prevention were fully vaccinated as of Feb. 5, 2022, leaving many expectant moms at a high risk of infection and life-threatening complications.

More than 29,000 pregnant people have been hospitalized with COVID-19 and 274 have died, according to the CDC.

“There were surely women who were hospitalized because there wasn’t information available to them,” said Paul A. Offit, MD, director of the Vaccine Education Center at the Children’s Hospital of Philadelphia.

Vaccine developers say that pregnant people – who have special health needs and risks – were excluded from clinical trials to protect them from potential side effects of novel technologies, including the Pfizer and Moderna mRNA vaccines and formulations made with cold viruses, such as the Johnson & Johnson vaccine.

But a KHN analysis also shows that pregnant people were left behind because including them in vaccine studies would have complicated and potentially delayed the delivery of COVID-19 vaccines to the broader population.

A growing number of women’s health researchers and advocates say that excluding pregnant people – and the months-long delay in recommending that they be immunized – helped fuel widespread vaccine hesitancy in this vulnerable group.

“Women and their unborn fetuses are dying of COVID infection,” said Jane Van Dis, MD, an ob.gyn. at the University of Rochester (N.Y.) Medical Center who has treated many patients like Ms. Slade. “Our failure as a society to vaccinate women in pregnancy will be remembered by the children and families who lost their mothers to this disease.”
 

New technology, uncertain risks

At the time COVID-19 vaccines were being developed, scientists had very little experience using mRNA vaccines in pregnant women, said Jacqueline Miller, MD, a senior vice president involved in vaccine research at Moderna.

“When you study anything in pregnant women, you have two patients, the mom and the unborn child,” Dr. Miller said. “Until we had more safety data on the platform, it wasn’t something we wanted to undertake.”

But Dr. Offit noted that vaccines have a strong record of safety in pregnancy and he sees no reason to have excluded pregnant people. None of the vaccines currently in use – including the chickenpox and rubella vaccines, which contain live viruses – have been shown to harm fetuses, he said. Doctors routinely recommend that pregnant people receive pertussis and flu vaccinations.

Dr. Offit, the coinventor of a rotavirus vaccine, said that some concerns about vaccines stem from commercial, not medical, interests. Drug makers don’t want to risk that their product will be blamed for any problems occurring in pregnant people, even if coincidental, he said.

“These companies don’t want bad news,” Dr. Offit said.

In the United States, health officials typically would have told expectant mothers not to take a vaccine that was untested during pregnancy, said Dr. Offit, a member of a committee that advises the Food and Drug Administration on vaccines.

Due to the urgency of the pandemic, health agencies instead permitted pregnant people to make up their own minds about vaccines without recommending them.

Women’s medical associations were also hampered by the lack of data. Neither the American College of Obstetricians and Gynecologists nor the Society for Maternal-Fetal Medicine actively encouraged pregnant people to be vaccinated until July 30, 2021, after the first real-world vaccine studies had been published. The CDC followed suit in August of 2021.

“If we had had this data in the beginning, we would have been able to vaccinate more women,” said Kelli Burroughs, MD, the department chair of obstetrics and gynecology at Memorial Hermann Sugar Land Hospital near Houston.

Yet anti-vaccine groups wasted no time in scaring pregnant people, flooding social media with misinformation about impaired fertility and harm to the fetus.

In the first few months after the COVID-19 vaccines were approved, some doctors were ambivalent about recommending them, and some still advise pregnant patients against vaccination.

An estimated 67% of pregnant people today are fully vaccinated, compared with about 89% of people 65 and older, another high-risk group, and 65% of Americans overall. Vaccination rates are lower among minorities, with 65% of expectant Hispanic mothers and 53% of pregnant African Americans fully vaccinated, according to the CDC.

Vaccination is especially important during pregnancy, because of increased risks of hospitalization, ICU admission, and mechanical ventilation, Dr. Burroughs said. A study released in February from the National Institutes of Health found that pregnant people with a moderate to severe COVID-19 infection also were more likely to have a C-section, deliver preterm, or develop a postpartum hemorrhage.

Black moms such as Ms. Slade were already at higher risk of maternal and infant mortality before the pandemic, because of higher underlying risks, unequal access to health care, and other factors. COVID-19 has magnified those risks, said Dr. Burroughs, who has persuaded reluctant patients by revealing that she had a healthy pregnancy and child after being vaccinated.

Ms. Slade said she has never opposed vaccines and had no hesitation about receiving other vaccines while pregnant. But she said she “just wasn’t comfortable” with COVID-19 shots.

“If there had been data out there saying the COVID shot was safe, and that nothing would happen to my baby and there was no risk of birth defects, I would have taken it,” said Ms. Slade, who has had type 2 diabetes for 12 years.
 

Working at warp speed

Government scientists at the NIH were concerned about the risk of COVID-19 to pregnant people from the very beginning and knew that expectant moms needed vaccines as much or more than anyone else, said Larry Corey, MD, a leader of the COVID-19 Prevention Network, which coordinated COVID-19 vaccine trials for the federal government.

But including pregnant volunteers in the larger vaccine trials could have led to interruptions and delays, Dr. Corey said. Researchers would have had to enroll thousands of pregnant volunteers to achieve statistically robust results that weren’t due to chance, he said.

Pregnancy can bring on a wide range of complications: gestational diabetes, hypertension, anemia, bleeding, blood clots, or problems with the placenta, for example. Up to 20% of people who know they’re pregnant miscarry. Because researchers would have been obliged to investigate any medical problem to make sure it wasn’t caused by one of the COVID-19 vaccines, including pregnant people might have meant having to hit pause on those trials, Dr. Corey said.

With death tolls from the pandemic mounting, “we had a mission to do this as quickly and as thoroughly as possible,” Dr. Corey said. Making COVID-19 vaccines available within a year “saved hundreds of thousands of lives.”

The first data on COVID-19 vaccine safety in pregnancy was published in April of 2021 when the CDC released an analysis of nearly 36,000 vaccinated pregnant people who had enrolled in a registry called V-safe, which allows users to log the dates of their vaccinations and any subsequent symptoms.

On Feb. 17, 2022, the updated Recommended Childhood and Adolescent Immunization Schedule was released by the Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention. Pediatric providers across the country eagerly await this annual update to learn what changes lie in store for recommended immunization practices. During the week that has gone by since the 2022 release, I’ve had a chance to reflect on some of the highlights that are worth noting.

The SARS-CoV-2 (COVID-19) vaccines are not on the schedule yet, undoubtedly because of the preliminary nature of the vaccine data for children and the emergency use authorization vaccine status. We currently have interim recommendations for childhood COVID-19 vaccines.
 

Brand new in 2022

Two new items in the 2022 schedules are worth reviewing. The first is an entirely new recommendation to administer dengue vaccine to children aged 9-16 years living in endemic areas, but only if they already have laboratory-confirmed past dengue infection. For U.S. practitioners, the endemic areas to remember are Puerto Rico and the U.S. Virgin islands in the Caribbean, as well as Pacific island areas, such as the Marshall Islands, Palau, and the Federated States of Micronesia. There is a link in the document to additional recommendations.

The second totally new item is the combination preparation, Vaxelis, which contains DTaP, inactivated poliovirus, Haemophilus influenzae b conjugate, and hepatitis B vaccines. There are extensive recommendations for how to work it into the vaccine schedule, including some situations when it should not be used.
 

Selected reminders in childhood immunization

I’ll start with some key reminders about what not to do. Remember that the live inactivated influenza virus vaccine (LAIV) is recommended to begin only at age 2 years and older, compared with the inactivated influenza vaccine, which begins at 6 months. In addition, LAIV is contraindicated in patients aged 2-4 years who have a history of asthma or wheezing. Remember to avoid live virus vaccines, such as LAIV, MMR, and varicella, during pregnancy but be ready to administer those vaccines right after delivery. Similarly, HPV vaccine should be delayed until after pregnancy.

There are many special situation recommendations; I’ll highlight only a few here. One reminder is that although MMR and hepatitis A are both recommended to begin at 12 months, infants aged 6-11 months who are undergoing international travel to high-risk areas can begin with one dose before departure and then receive a two-dose series after turning 12 months of age.

Pneumococcal vaccination. Some children should receive both the pneumococcal conjugate vaccine (PCV13) and the pneumococcal polysaccharide vaccine (PPSV23). Those groups include children with chronic heart disease, chronic lung disease, diabetes, cerebral spinal fluid leaks or cochlear implants, and sickle cell disease, as well as many other immunocompromising conditions. Kids who need both preparations should receive the conjugate vaccine first, but they should never receive the conjugate vaccine and the polysaccharide vaccine at the same visit.

Meningococcal vaccination. Meningococcal vaccine special situations can be quite complicated. For meningococcus A,C,W,Y (MenACWY) vaccination, children with immunocompromising conditions should receive different schedules from those of typical children, but the recommendations vary by preparation.

For adolescents aged 16-23 years, the decision whether to administer the meningococcal serogroup B (MenB) vaccine is based on shared clinical decision-making, a recommendation that began in 2020. Patients with certain immunocompromising conditions are considered at higher risk and should more routinely receive MenB vaccination, with recommendations varying depending on the preparation utilized. The MenB preparations are not interchangeable. In addition, patients may receive both MenACWY and MenB vaccines on the same day, but they should be given at different body sites.
 

A few final reminders

In certain cases, you might avoid administering what would otherwise be routine vaccinations. For example, the rotavirus series should not begin if the infant is aged 15 weeks or older. Only one dose of Haemophilus influenzae b vaccine is indicated after age 15 months and none at 60 months or older if the child does not have high-risk conditions.

Finally, the total number of doses for some vaccines, such as pneumococcus and polio, vary depending on how old the child is if not already fully vaccinated. For example, for pneumococcal conjugate vaccine catch-up in a healthy child, one dose after age 24 months would bring the child up to date. For inactivated poliovirus in children aged 4 years or older, a third dose given at least 6 months after the second dose would bring that child up to date.

The tables can be a challenge to interpret, but fortunately simpler tables for parents are available. These make excellent handouts to have available in the office!

Introduction

Amidst an aggressive vaccination campaign for COVID-19, misinformation has spread over the Internet, affecting public perception and making some people hesitant to participate in ongoing immunization campaigns. Of chief concern are issues pertaining to fertility or viability of sperm – information circulating on social networks posits that the coronavirus vaccine may influence infertility in men, which, according to physicians, is not grounded in reality. From the perspective of evidence-based medicine, there is a dearth of information suggesting an untoward effect of the vaccine on male fertility. The risk of adverse reactions arising from approved vaccines is negligible, with mild, albeit controllable, side effects demonstrated by patients in clinical trials. Therefore, there is no plausible reason for the general public to avoid vaccinations.¹

Infertility following vaccination

The source of confusion can be traced back to a study conducted by researchers at the University of Miami Miller School of Medicine; the general public has conflated a side effect of the virus, namely, infertility and erectile dysfunction, with that of the vaccine.² According to Ranjith Ramasamy, MD, director of the urology program at Miller, “We were the first to demonstrate that the COVID virus, itself, can affect male fertility and be a potential cause for erectile dysfunction. We are now the first to examine if there is any impact of the COVID vaccine on male fertility potential, which we did not find.”³

Coronavirus can indeed cause significant damage to the testicular tissue of infected men by means of mediating ACE2 expression on Leydig and Sertoli cells of the testis. It should be noted that COVID-19 may potentially attack any type of cell in the body that expresses the enzyme ACE2. However, it is particularly harmful to cells with high levels of expression of this enzyme, such as testicular cells. The spermatogenesis process can be affected, thereby posing a risk to male fertility.⁴

Expanding on the theme of fertility during the pandemic, a number of false claims^5-7 about the vaccine and its overall effect on the placenta and fertility have also emerged as a contentious topic for debate on social media; doctors continue to explain why the theories are not reasonable or a cause for concern. The World Health Organization (WHO) provides recommendations on COVID-19 vaccinations for pregnant and/or lactating women and encourages a shared decision process involving risk/benefit assessment with the prescribing physician.⁵ Pregnant women, especially those with underlying comorbid conditions, are susceptible to developing severe symptom manifestations of COVID-19 with the disease also being associated with an increased likelihood of premature birth. As far as lactating women are concerned, the evidence thus far has indicated that the risk of side effects of the vaccine is very low, suggesting that these women could be vaccinated.⁵

The vaccine is the best option

While more studies are needed to ascertain the relationship between COVID-19 and male infertility, the vaccine is currently the best option for those who are concerned about their fertility from exposure to the coronavirus. Because of delayed wholesale acceptance of vaccines by the general population, clinicians should continue to emphasize the importance of preventive care with respect to disease exposure.⁶

In addition, those who are concerned with fertility can opt for ways to preserve their reproductive capacity, such as the removal of semen for freezing sperm, albeit with adherence to sperm-washing procedures to preclude cross-contamination from viruses.^8,9 For the preservation of sperm, the noninvasive method is often performed, preferably collected in several samples. Then, the semen is cryopreserved.⁸ In some instances, the sperm can also be removed directly from the testicles with a simple needle or by means of a minor surgical procedure.

Introduction

Amidst an aggressive vaccination campaign for COVID-19, misinformation has spread over the Internet, affecting public perception and making some people hesitant to participate in ongoing immunization campaigns. Of chief concern are issues pertaining to fertility or viability of sperm – information circulating on social networks posits that the coronavirus vaccine may influence infertility in men, which, according to physicians, is not grounded in reality. From the perspective of evidence-based medicine, there is a dearth of information suggesting an untoward effect of the vaccine on male fertility. The risk of adverse reactions arising from approved vaccines is negligible, with mild, albeit controllable, side effects demonstrated by patients in clinical trials. Therefore, there is no plausible reason for the general public to avoid vaccinations.¹

Infertility following vaccination

The source of confusion can be traced back to a study conducted by researchers at the University of Miami Miller School of Medicine; the general public has conflated a side effect of the virus, namely, infertility and erectile dysfunction, with that of the vaccine.² According to Ranjith Ramasamy, MD, director of the urology program at Miller, “We were the first to demonstrate that the COVID virus, itself, can affect male fertility and be a potential cause for erectile dysfunction. We are now the first to examine if there is any impact of the COVID vaccine on male fertility potential, which we did not find.”³

Coronavirus can indeed cause significant damage to the testicular tissue of infected men by means of mediating ACE2 expression on Leydig and Sertoli cells of the testis. It should be noted that COVID-19 may potentially attack any type of cell in the body that expresses the enzyme ACE2. However, it is particularly harmful to cells with high levels of expression of this enzyme, such as testicular cells. The spermatogenesis process can be affected, thereby posing a risk to male fertility.⁴

Expanding on the theme of fertility during the pandemic, a number of false claims^5-7 about the vaccine and its overall effect on the placenta and fertility have also emerged as a contentious topic for debate on social media; doctors continue to explain why the theories are not reasonable or a cause for concern. The World Health Organization (WHO) provides recommendations on COVID-19 vaccinations for pregnant and/or lactating women and encourages a shared decision process involving risk/benefit assessment with the prescribing physician.⁵ Pregnant women, especially those with underlying comorbid conditions, are susceptible to developing severe symptom manifestations of COVID-19 with the disease also being associated with an increased likelihood of premature birth. As far as lactating women are concerned, the evidence thus far has indicated that the risk of side effects of the vaccine is very low, suggesting that these women could be vaccinated.⁵

The vaccine is the best option

While more studies are needed to ascertain the relationship between COVID-19 and male infertility, the vaccine is currently the best option for those who are concerned about their fertility from exposure to the coronavirus. Because of delayed wholesale acceptance of vaccines by the general population, clinicians should continue to emphasize the importance of preventive care with respect to disease exposure.⁶

In addition, those who are concerned with fertility can opt for ways to preserve their reproductive capacity, such as the removal of semen for freezing sperm, albeit with adherence to sperm-washing procedures to preclude cross-contamination from viruses.^8,9 For the preservation of sperm, the noninvasive method is often performed, preferably collected in several samples.

The American Academy of Pediatrics said it supports the Recommended Childhood and Adolescent Immunization Schedule: United States, 2022.

In a policy statement published online Feb. 17 in Pediatrics, the AAP said the updated recommendations differ little from those released last year by the Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention.

“The only significant change this year was to add the dengue vaccine to the schedule,” Sean T. O’Leary, MD, MPH, vice chair of the AAP’s 2021-2022 Committee on Infectious Diseases and a coauthor of the statement, told this news organization. “But that is really only relevant for children living in endemic areas, primarily Puerto Rico but some other smaller U.S .territories as well.”

Dengue fever also is endemic in American Samoa and the U.S. Virgin Islands.

Notably, a new section has been added on routine recommendations for use of the Dengvaxia vaccine.

The 2022 policy statement addresses regular immunization of children from birth to 18 years and catch-up vaccination for those aged 4 months to 18 years. In addition to the AAP, multiple complementary physician and nurse organizations have approved the updates. The ACIP schedule is revised annually to reflect current recommendations on vaccines licensed by the U.S. Food and Drug Administration.

Most of the other changes this year involve minor updates to clarify language or improve usability. “CDC and AAP are always working to make the schedule as user-friendly as possible, with improvements made every year,” Dr. O’Leary, professor of pediatric infectious diseases at the University of Colorado at Denver, Aurora, said.

In terms of physician acceptance, he added, “I don’t think any of the changes would be considered controversial.”

Among other updates and clarifications:

• For Haemophilus influenzae type b (Hib) vaccination, the text now includes recommendations for the hexavalent Vaxelis vaccine (diphtheria, tetanus, pertussis, polio, Hib, and hepatitis B) for both routine and catch-up vaccination.
• For hepatitis A, the relevant note has been updated to clarify the age for routine vaccination.
• For human papillomavirus (HPV), the note now clarifies when an HPV series is complete with no additional dose recommended.
• The special situations section has been amended to specify which persons with immunocompromising conditions such as HIV should receive three doses of HPV vaccine regardless of age at initial vaccination.
• For measles, mumps, and rubella, routine vaccination now includes recommendations on the combination measles, mumps, rubella, and varicella vaccine.
• For meningococcal serogroup A, C, W, and Y vaccines, the augmented text explains when these can be simultaneously administered with serogroup B meningococcal vaccines, preferably at different anatomic sites. The language for the dosing schedule for Menveo vaccination in infants also has been clarified.
• In the catch-up immunization schedule for late-starting children aged 4 months to 18 years, the text on Hib has been changed so that the minimum interval between dose two and dose three now refers to Vaxelis, while reference to the discontinued Comvax (Hib-Hep B) vaccine has been removed.

As in other years, graphic changes have been made to table coloration and layout to improve accessibility. And as before, the 2022 childhood and adolescent immunization schedule has been updated to ensure consistency between its format and that of the 2022 adult immunization schedules.

The AAP committee stressed that clinically significant adverse events after immunization should be reported to the Vaccine Adverse Event Reporting System.

The full 2022 schedule can be found on the CDC’s website.

The recommended vaccination schedule for people in the United States aged 19 years and older has been released by the Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention (CDC).

The Clinical Guideline on the “Recommended Adult Immunization Schedule, United States, 2022” appears online Feb. 17 in Annals of Internal Medicine and in the CDC’s Morbidity and Mortality Weekly Report.

The document features changes to the zoster, pneumococcal, and hepatitis B vaccines. COVID-19 vaccinations are now included in the notes section of the schedule and can be co-administered with other vaccines, according to ACIP.

The 2022 schedule is particularly important because the pandemic has caused many adults to fall behind in routine vaccinations, according to lead author Neil Murthy, MD, MPH, MSJ, of the CDC’s immunization services division, National Center for Immunization and Respiratory Diseases, and colleagues.  

“Providers should administer all due and overdue vaccines according to the routine immunization schedule during the same visit,” the group wrote. “In addition, providers should implement strategies to catch up all patients on any overdue vaccines.”

Among other changes appearing in the 2022 recommendations:

• A new step 4 in the form of an appendix lists all the contraindications and precautions for each vaccine.
• The zoster vaccine now is recommended for use in everyone aged 19 years and older who are or will be immunodeficient or immunosuppressed through disease or therapy. The new purple color bar reflects ACIP’s new two-dose series regimen for immunocompromised adults aged 19 to 49.
• The simplified pneumococcal recommendation includes guidance on using the new PCV15 and PCV20 vaccines.
• The hepatitis B recommendation has been made more inclusive, with vaccination recommended for all adults aged 19 to 59. The Special Situations section in the Notes outlines the risk-based recommendations for the hepatitis B vaccine in adults aged 60 and older. The schedule has been harmonized with the 2022 Child and Adolescent Immunization Schedule.

A welcome change

Sandra A. Fryhofer, MD, a member of the ACIP Combined Immunization Work Group, said the new pneumococcal recommendation is a particularly welcome change.

“The old recommendation was complicated and confusing. The new one is much more straightforward,” Dr. Fryhofer, an internist in Atlanta, said in an interview. Now there are only two options: a two-vaccine series of PCV15 (Vaxneuvance), in combination with the already familiar PPSV23 polysaccharide vaccine (Pneumovax 23), and a single dose of the new PCV20, Prevnar 20.

“Some work group members favored a universal age-based recommendation starting at 50 instead of 65,” Fryhofer said. “This would provide more opportunities to vaccinate adults but could lead to waning immunity later in life when risk of disease is higher.”

Although none of the updates is likely to stir controversy, discussion among ACIP members was particularly lively around hepatitis B vaccination, Dr. Fryhofer said. This vaccine has historically been recommended based on risk and has had poor uptake, while age-based vaccine recommendations generally have greater uptake.

“ACIP approved hepatitis B vaccine universally for those up to age 60, but for those 60 and older, the recommendation remains risk-based with a loophole: Anyone 60 and older who wants it can get it,” she told this news organization. “Some of the risk indications for hepatitis B vaccination may be uncomfortable or embarrassing to disclose, especially for older patients. The loophole takes care of that, but patients may have to ask for the vaccine.”

As usual, the graphics have been fine-tuned for greater accuracy and readability. “You can print a color copy to have in the exam room or at your workspace or give it a bookmark and check it online,” Dr. Fryhofer said. “It’s a great resource to have at your fingertips.”

Dr. Fryhofer has made a series of videos explaining ACIP’s approval process, the use of the schedule, and changes to vaccines including influenza. These can be accessed on the American College of Physicians website.

The authors of the recommendations stress that physicians should pay careful attention to the notes section for each vaccine, as these details clarify who needs what vaccine, when, and at what dose.

Co-author Henry Bernstein, DO, reported that he is the editor of Current Opinion in Pediatrics Office Pediatrics Series and received a presentation honorarium from the Florida chapter of the American Academy of Pediatrics. Co-author Kevin Ault, MD, reported having received a grant from the National Cancer Institute, consulting fees from PathoVax, and payments supporting attending meetings and/or travel from the American College of Obstetricians and Gynecologists.

The recommended vaccination schedule for people in the United States aged 19 years and older has been released by the Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control and Prevention (CDC).

The Clinical Guideline on the “Recommended Adult Immunization Schedule, United States, 2022” appears online Feb. 17 in Annals of Internal Medicine and in the CDC’s Morbidity and Mortality Weekly Report.

The document features changes to the zoster, pneumococcal, and hepatitis B vaccines. COVID-19 vaccinations are now included in the notes section of the schedule and can be co-administered with other vaccines, according to ACIP.

The 2022 schedule is particularly important because the pandemic has caused many adults to fall behind in routine vaccinations, according to lead author Neil Murthy, MD, MPH, MSJ, of the CDC’s immunization services division, National Center for Immunization and Respiratory Diseases, and colleagues.  

“Providers should administer all due and overdue vaccines according to the routine immunization schedule during the same visit,” the group wrote. “In addition, providers should implement strategies to catch up all patients on any overdue vaccines.”

Among other changes appearing in the 2022 recommendations:

• A new step 4 in the form of an appendix lists all the contraindications and precautions for each vaccine.
• The zoster vaccine now is recommended for use in everyone aged 19 years and older who are or will be immunodeficient or immunosuppressed through disease or therapy. The new purple color bar reflects ACIP’s new two-dose series regimen for immunocompromised adults aged 19 to 49.
• The simplified pneumococcal recommendation includes guidance on using the new PCV15 and PCV20 vaccines.
• The hepatitis B recommendation has been made more inclusive, with vaccination recommended for all adults aged 19 to 59. The Special Situations section in the Notes outlines the risk-based recommendations for the hepatitis B vaccine in adults aged 60 and older. The schedule has been harmonized with the 2022 Child and Adolescent Immunization Schedule.

A welcome change

Sandra A. Fryhofer, MD, a member of the ACIP Combined Immunization Work Group, said the new pneumococcal recommendation is a particularly welcome change.

“The old recommendation was complicated and confusing. The new one is much more straightforward,” Dr. Fryhofer, an internist in Atlanta, said in an interview. Now there are only two options: a two-vaccine series of PCV15 (Vaxneuvance), in combination with the already familiar PPSV23 polysaccharide vaccine (Pneumovax 23), and a single dose of the new PCV20, Prevnar 20.

“Some work group members favored a universal age-based recommendation starting at 50 instead of 65,” Fryhofer said. “This would provide more opportunities to vaccinate adults but could lead to waning immunity later in life when risk of disease is higher.”

Although none of the updates is likely to stir controversy, discussion among ACIP members was particularly lively around hepatitis B vaccination, Dr. Fryhofer said. This vaccine has historically been recommended based on risk and has had poor uptake, while age-based vaccine recommendations generally have greater uptake.

“ACIP approved hepatitis B vaccine universally for those up to age 60, but for those 60 and older, the recommendation remains risk-based with a loophole: Anyone 60 and older who wants it can get it,” she told this news organization. “Some of the risk indications for hepatitis B vaccination may be uncomfortable or embarrassing to disclose, especially for older patients. The loophole takes care of that, but patients may have to ask for the vaccine.”

As usual, the graphics have been fine-tuned for greater accuracy and readability. “You can print a color copy to have in the exam room or at your workspace or give it a bookmark and check it online,” Dr. Fryhofer said. “It’s a great resource to have at your fingertips.”

Dr. Fryhofer has made a series of videos explaining ACIP’s approval process, the use of the schedule, and changes to vaccines including influenza. These can be accessed on the American College of Physicians website.

The authors of the recommendations stress that physicians should pay careful attention to the notes section for each vaccine, as these details clarify who needs what vaccine, when, and at what dose.

In a first of its kind study, researchers found women who received two mRNA COVID vaccine doses during pregnancy were 61% less likely to have a baby hospitalized for COVID-19 during the first 6 months of life.

In addition, two doses of the Pfizer/BioNTech or Moderna COVID vaccine later in a pregnancy were linked to an even higher level of protection, 80%, compared with 32% when given before 20 weeks’ gestation.

This finding suggests a greater transfer of maternal antibodies closer to birth, but more research is needed, cautioned senior study author Manish Patel, MD, during a Tuesday media telebriefing held by the Centers for Disease Control and Prevention.

Unanswered questions include how the babies got infected or if there is any protection afforded to babies for women vaccinated before pregnancy.

“We cannot be sure about the source of the infection,” said Dr. Patel, a medical epidemiologist with the CDC COVID-19 Emergency Response Team.

Dana Meaney-Delman, MD, MPH, agreed, but added that “perinatal transmission of the virus is very rare” with SARS-CoV-2. She is a practicing obstetrician and gynecologist and chief of the CDC Infant Outcomes Monitoring Research and Prevention Branch.

The study numbers were too small to show if a booster shot during pregnancy or breastfeeding could provide even greater protection for babies, Dr. Patel said.

The early release study was published online Feb. 15 in the CDC’s Morbidity and Mortality Weekly Report (MMWR).

Many previous studies looking at COVID-19 immunization during pregnancy focused on maternal health and “have clearly shown that receiving an mRNA COVID-19 vaccine during pregnancy reduces the risk for severe illness,” Dr. Meaney-Delman said.
 

Some dual protection suggested

Now there is evidence for a potential benefit to babies as well when a pregnant woman gets vaccinated. The study “provides real-world evidence that getting COVID-19 vaccination during pregnancy might help protect infants less than 6 months [of age],” Dr. Meaney-Delman said.

“These findings continue to emphasize the importance of COVID-19 vaccination during pregnancy to protect people who are pregnant and also to protect their babies,” she said.

Dr. Patel and colleagues studied 379 infants younger than 6 months hospitalized between July 1, 2021 and Jan. 17 of this year. Delta and then the Omicron variant predominated during this time.

The infants were admitted to one of 20 children’s hospitals in 17 states. The researchers compared 176 infants admitted with a positive COVID-19 PCR test to another 203 infants with a negative PCR test who served as controls. 

Half as many mothers of infants admitted with COVID-19 were vaccinated during pregnancy, 16%, versus 32% of mothers of the control infants.

Vaccination with two doses of mRNA vaccine during pregnancy was 61% effective (95% confidence interval, 31%-78%) at preventing hospitalization among these infants. Because the study was epidemiological, the lower risk was an association, not a cause-and-effect finding, Dr. Patel said.

Babies admitted to the hospital positive for COVID-19 were more likely to be non-Hispanic Black, 18%, versus 9% of control group babies; and more likely to be Hispanic, 34% versus 28%, respectively.

A total 24% of infants with COVID-19 were admitted to the ICU, including the baby of an unvaccinated mother who required extracorporeal membrane oxygenation (ECMO). Another baby of an unvaccinated mother was the only infant death during the study.
 

Maternal vaccination trends

A reporter pointed out that COVID-19 vaccination rates tend to be low among pregnant women. “So there is some exciting news,” Dr. Meaney-Delman said, referring to a steady increase in the percentages of pregnant women in the U.S. choosing to get vaccinated, according to the CDC Data Tracker website.

“The numbers are encouraging, [but] they’re not quite where we need them to be, and they do differ by race and ethnicity,” she added.

The picture of rebellious teenagers sneaking “shots” has widened beyond breaking into Mom and Dad’s liquor cabinet. For some teens now, it means getting a COVID-19 vaccination without their parents’ consent – and, unlike the cabinet raids for the booze, they have adults willing to endorse the practice.

Since the U.S. Food and Drug Administration first granted emergency use authorization to Pfizer’s COVID-19 vaccine for teenagers in mid-2021, health officials have had to deal with a small subset of vaccine hesitancy where minors want the shot over the objections of their reluctant parents. The split has buoyed groups that were formed initially to convince teenagers to get vaccinated against other diseases.

When 14-year-old Arin Parsa of San Jose, California founded Teens for Vaccines in 2019 after a measles outbreak among unvaccinated children, “hardly anyone was interested,” he said. “Many teens were into climate change and other causes. Then, when the pandemic hit, so many were suddenly aware.”
 

Heavy toll on teens

Mr. Parsa’s parents fully supported Teens for Vaccines, he said, but he quickly found out how “politicized” COVID shots had become.

“We find people who are sad, angry, and frustrated at this stage of the pandemic,” he told this news organization. “The anti-vax lobby is riding the coat-tails of other movements. It has a very severe effect on their mental health. They can’t go out with their friends and socialize.”

In the pandemic’s initial stages, children were less likely to fall sick with COVID, but the Omicron variant led to a dramatic increase in illnesses among young people. The American Academy of Pediatrics has found that 3.5 million of the 11.4 million pediatric cases of the virus in the United States were reported in January 2022 alone. Meanwhile, vaccination rates for children aged 12-17, which were only 34% in June 2021 and lagged through the fall, are now at about 61% thanks to a sharp uptick during the Omicron surge, according to polling by the Kaiser Family Foundation.

No statistics are available on how many minors have received a COVID vaccine against their parents’ wishes.

“It’s not like there’s a big movement,” said Arthur Caplan, PhD, who heads the Division of Medical Ethics at the NYU Grossman School of Medicine. He said he noticed a divide around the HPV and hepatitis B vaccines. “They were tied up with sexual behavior,” he said, but “there were also some kids whose parents were really antivaxxers.”

Mr. Parsa said his and similar teen-oriented groups, such as VaxTeen, seek to educate their teen cohort, convince family members of the vaccines’ benefits, and to connect them with resources to get a shot. They also strive to change laws to make it easier for teenagers to receive the vaccine.

Consent laws vary from state to state (and within states), and proposed changes are afoot – some to loosen the laws and some to tighten them. Currently a 14-year-old in Alabama may get a COVID shot without parental permission, according to VaxTeen. In California, minors may receive the HPV shot without parental consent but not a COVID vaccine, although groups like Teens for Vaccines are pushing to change that. A bill now before the state legislature, the Teens Choose Vaccines Act (Senate Bill 866), would allow adolescents aged 12 and older to be able receive any FDA-approved vaccine – including COVID vaccines – without parental consent.

A second bill in California, the Keep Schools Open and Safe Act, would add the COVID-19 vaccines to the required list of immunizations needed to attend school in the state as well as eliminate the “personal belief” exemption against immunization. 

California Sen. Richard Pan, MD (D-6th District), cowrote both bills with fellow Democrat Sen. Scott Wiener (D-11th District) and teen advocates from Teens for Vaccines and Generation Up, who helped draft the language in consultation with the lawmakers.  

“As a pediatrician, I have seen all manner of situations where the requirement for a signed form has prevented teens from being able to get a vaccine that otherwise they and their guardians approved of them getting,” Dr. Pan told this news organization. “As a father, I don’t want to see my kids or any teen that wishes to protect themselves from deadly diseases unable to do so, particularly as we continue to fight off the dangers of the COVID-19 pandemic. I always encourage parents or teens that have questions about vaccines to speak directly with their pediatrician.”

Lawmakers in Philadelphia passed a provision last year to allow anyone age 11 or over to get the COVID vaccine without parental permission, keeping it in line with other vaccinations like hepatitis or HPV. “People from surrounding counties have come into the city, but it hasn’t been a huge rush,” says James Garrow, MPH, a spokesman for the city’s Department of Health.
 

Strive for collaboration, but listen to the children

Experts say the best solution is to for a doctor to meet with minors and their reluctant parents to get them on board for a COVID shot.

“Physicians are still the trusted messengers,” said Emma Olivera, MD, a pediatrician in suburban Chicago who advises groups that combat COVID misinformation.

Dr. Olivera said she often finds that internet-savvy teenagers have access to more information than older people, including their parents.  

Thanks to COVID policies, office meetings are “difficult to do,” NYU’s Dr. Caplan added. In such a meeting, Dr. Caplan said he would try to convince the parents that the shots are needed for their children to stay in school or play sports. In the end, he said minors should get the shot but would also notify the parents before that happens: “My duty is to them.”

If parents take opposite stances, the pro-vaccine side is likely to prevail, even in California, said Patrick Baghdaserians, JD, a family law attorney in Pasadena. Mr. Baghdaserians said he is now representing a father who wants his teenager to get vaccinated but the mother doesn’t. “The court will fall on our side,” he predicted.

The Food and Drug Administration said Feb. 11 it would delay a decision on authorizing the use of the Pfizer vaccine for younger children until data on the effects of three doses is available.

Peter Marks, MD, director of the FDA’s Center for Biologics Evaluation and Research, said the plan for a meeting the week of Feb. 14 of the FDA’s Vaccines and Related Biological Products Advisory Committee was to “understand if two doses would provide sufficient protection to move forward.”

Pfizer has asked the FDA to authorize the use of its mRNA vaccine for children under the age of 5. But, Dr. Marks said, “in looking through the data we realized now … that at this time it makes sense for us to wait until we have the data of the evaluation of a third dose before taking action.”

Screening for hepatitis B antibodies and vaccinating pregnant women without immunity appears to be a cost-effective health measure, according to a recent analysis published in Obstetrics & Gynecology.

Malavika Prabhu, MD, of the division of maternal-fetal medicine and department of obstetrics and gynecology at Weill Cornell Medicine in New York, said in an interview that the impetus to conduct the study came from the idea that hepatitis B is a concern throughout a woman’s life, but not necessarily during pregnancy. While vaccination is not routine during pregnancy, guidelines from the American College of Obstetricians and Gynecologists state that at-risk women should be screened and vaccinated for hepatitis B during pregnancy.

“What we thought made more sense just from thinking about other principles of prenatal care was that it would make sense for us to screen, see who’s susceptible, counsel them on the risk of hepatitis B, and then vaccinate them in the course of the pregnancy,” Dr. Prabhu said.

After writing a commentary arguing in favor of universal screening and vaccination, she and her colleagues noted it was still unclear whether that approach was cost effective, she said. “Health care costs in this country are so expensive at baseline that, as we continue to add more things to health care, we have to make sure that it’s value added.”

Dr. Prabhu and her colleagues evaluated a theoretical cohort of 3.6 million pregnant women in the United States and created a decision-analytic model to determine how universal hepatitis B surface antibody screening and vaccination for hepatitis B affected factors such as cost, cost-effectiveness, and outcomes. They included hepatitis B virus cases as well as long-term problems associated with hepatitis B infection such as hepatocellular carcinoma, decompensated cirrhosis, liver transplant, and death. Assumptions of the model were that 84% of the women would undergo the screening, 61% would receive the vaccine, and 90% would seroconvert after the vaccine series, and were based on probabilities from other studies.

The cost-effectiveness ratio was calculated as the total cost and quality-adjusted life-years (QALYs) relative to the lifetime of the woman after the index pregnancy, with $50,000 per QALY set as the willingness-to-pay threshold. The researchers also performed an additional analysis and simulations to estimate which variables had the most effect, and an additional model was created to estimate the effect of universal screening and vaccination if at-risk patients were removed.

Dr. Prabhu and colleagues found the universal screening and vaccination program was cost effective, with 1,702 fewer cases of hepatitis B, 11 fewer deaths, 7 fewer decompensated cirrhosis cases, and 4 fewer liver transplants in their model. The incremental cost-effectiveness ratio was $1,890 per QALY, and the total increased lifetime cohort cost was $13,841,889. The researchers said the model held up in scenarios where there was a high level of hepatitis B immunity, and when at-risk women were removed from the model.

“While it does increase some costs to the health care system to screen everyone and vaccinate those susceptible; overall, it would cost more to not do that because we’re avoiding all of those long-term devastating health outcomes by vaccinating in pregnancy,” Dr. Prabhu said in an interview.
 

Hepatitis B screening and vaccination for all pregnant women?

Is universal hepatitis B screening and vaccination for pregnant women an upcoming change in prenatal care? In a related editorial, Martina L. Badell, MD, of the division of maternal-fetal medicine and department of gynecology and obstetrics at Emory University School of Medicine in Atlanta, emphasized the hepatitis B vaccine’s safety and effectiveness during pregnancy based on prior studies and compared a universal hepatitis B screening and vaccination program for pregnant women to how clinicians screen universally for rubella as standard of care in this group.

“Owing to the success of rubella vaccination campaigns, today there are fewer than 10 cases of rubella in the United States annually, and, since 2012, all of these cases have been in persons infected when living in or traveling to other countries,” she wrote. “Approximately 850,000 people are living with hepatitis B infection in the United States, and approximately 21,900 acute hepatitis B infections occurred in 2015. Despite the very different prevalence in these infections, we currently screen pregnant and nonpregnant patients for rubella immunity but not hepatitis B.”

If real-world studies bear out that a hepatitis B universal screening and vaccination program is cost effective, guidelines on who should be screened and vaccinated might need to be reconsidered, Dr. Prabhu said. Although following women for decades to see whether hepatitis B screening and vaccination is cost effective is impractical, “a lot of medicine has been predicated on risk-based strategies and risk stratifying, and there is a lot of value to approaching patients like that,” she explained.

How an ob.gyn. determines whether a patient is high risk and qualifies for hepatitis B vaccination under current guidelines is made more complicated by the large amount of information covered in a prenatal visit. There is a “laundry list” of risk factors to consider, and “patients are just meeting you for the first time, and so they may not feel comfortable completely sharing what their risk factors may or may not be,” Dr. Prabhu said. In addition, they may not know the risk factors of their partners.

Under guidelines where all pregnant women are screened and vaccinated for hepatitis B regardless of risk, “it doesn’t harm a woman to check one extra blood test when she’s already having this bevy of blood tests at the first prenatal visit,” she said.

Clinicians may be more aware of the need to add hepatitis B screening to prenatal care given that routine hepatitis C screening for pregnant women was recently released by ACOG as a practice advisory. “I think hepatitis is a little bit more on the forefront of the obstetrician or prenatal care provider’s mind as a result of that recent shift,” she said.

“A lot of women only really access care and access consistent care during their pregnancy, either due to insurance reasons or work reasons. People do things for their developing fetus that they might not do for themselves,” Dr. Prabhu said. “It’s a unique opportunity to have the time to build a relationship, build some trust in the health care system and also educate women about their health and what they can do to keep themselves in good health.

“It’s more than just about the next 9 months and keeping you and your baby safe, so I think there’s a real opportunity for us to think about the public health and the long-term health of a woman.”
