Vaccines

The intention to vaccinate children against COVID-19 was lower among vaccine-hesitant parents when compared with parents who were willing to or had already received the COVID vaccine, a new survey finds.

“Parental vaccine hesitancy is a major issue for schools resuming in-person instruction, potentially requiring regular testing, strict mask wearing, and physical distancing for safe operation,” wrote lead author Madhura S. Rane, PhD, from the City University of New York in New York City, and colleagues in their paper, published online in JAMA Pediatrics.

The survey was conducted in June 2021 of 1,162 parents with children ranging in age from 2 to 17 years. The majority of parents (74.4%) were already vaccinated/vaccine-willing ,while 25.6% were vaccine hesitant. The study cohort, including both 1,652 children and their parents, was part of the nationwide CHASING COVID.

Vaccinated parents overall were more willing to vaccinate or had already vaccinated their eligible children when compared with vaccine-hesitant parents: 64.9% vs. 8.3% for children 2-4 years of age; 77.6% vs. 12.1% for children 5-11 years of age; 81.3% vs. 13.9% for children 12-15 years of age; and 86.4% vs. 12.7% for children 16-17 years of age; P < .001.

The researchers found greater hesitancy among Black and Hispanic parents, compared with parents who were non-Hispanic White, women, younger, and did not have a college education. Parents of children who were currently attending school remotely or only partially, were found to be more willing to vaccinate their children when compared to parents of children who were attending school fully in person.

The authors also found that parents who knew someone who had died of COVID-19 or had experienced a prior COVID-19 infection, were more willing to vaccinate their children.

Hesitance in vaccinated parents

Interestingly, 10% of COVID-vaccinated parents said they were still hesitant to vaccinate their kids because of concern for long-term adverse effects of the vaccine.

“These data point out that vaccine concerns may exist even among vaccinated or vaccine-favorable parents, so we should ask any parent who has not vaccinated their child whether we can discuss their concerns and perhaps move their opinions,” said William T. Basco Jr, MD, MS, a professor of pediatrics at the Medical University of South Carolina, Charleston, and director of the division of general pediatrics.

In an interview, when asked whether recent approval of the vaccine for children aged 5-11 will likely aid in overcoming parental hesitancy, Dr. Basco replied: “Absolutely. As more children get the vaccine and people know a neighbor or nephew or cousin, etc., who received the vaccine and did fine, it will engender greater comfort and allow parents to feel better about having their own child receive the vaccine.”

Advice for clinicians from outside expert

“We can always start by asking parents if we can help them understand the vaccine and the need for it. The tidal wave of disinformation is huge, but we can, on a daily basis, offer to help families navigate this decision,” concluded Dr. Basco, who was not involved with the new paper.

A new survey from the National Foundation for Infectious Diseases shows that, despite the recommendation that patients who have chronic illnesses receive annual flu vaccines, only 45% of these patients do get them. People with chronic diseases are at increased risk for serious flu-related complications, including hospitalization and death.

The survey looked at physicians’ practices toward flu vaccination and communication between health care providers (HCP) and their adult patients with chronic health conditions.

Overall, less than a third of HCPs (31%) said they recommend annual flu vaccination to all of their patients with chronic health conditions. There were some surprising differences between subspecialists. For example, 72% of patients with a heart problem who saw a cardiologist said that physician recommended the flu vaccine. The recommendation rate dropped to 32% of lung patients seeing a pulmonary physician and only 10% of people with diabetes who saw an endocrinologist.

There is quite a large gap between what physicians and patients say about their interactions. Fully 77% of HCPs who recommend annual flu vaccination say they tell patients when they are at higher risk of complications from influenza. Yet only 48% of patients say they have been given such information.

Although it is critically important information for patients to learn, their risk of influenza is often missing from the discussion. For example, patients with heart disease are six times more likely to have a heart attack within 7 days of flu infection. People with diabetes are six times more likely to be hospitalized from flu and three times more likely to die. Similarly, those with asthma or chronic obstructive pulmonary disorder are at a much higher risk of complications.

One problem is that more than half of specialist physicians who do not offer flu vaccinations report that it is because they believe that immunizations are the responsibility of the primary care physician. Yet only 65% of patients with one of these chronic illnesses report seeing their primary care physician at least annually.

Much of the disparity between the patient’s perception of what they were told and the physician’s is “how the ‘recommendation’ is actually made,” William Schaffner, MD, NFID’s medical director and professor of medicine at Vanderbilt University, Nashville, Tenn., told this news organization. Dr. Schaffner offered the following example: At the end of the visit, the doctor might say: “It’s that time of the year again – you want to think about getting your flu shot.”

“The doctor thinks they’ve recommended that, but the doctor really has opened the door for you to think about it and leave [yourself] unvaccinated.”

Dr. Schaffner’s alternative? Tell the patient: “‘You’ll get your flu vaccine on the way out. Tom or Sally will give it to you.’ That’s a very different kind of recommendation. And it’s a much greater assurance of providing the vaccine.”

Another major problem, Dr. Schaffner said, is that many specialists “don’t think of vaccination as something that’s included with their routine care” even though they do direct much of the patient’s care. He said that physicians should be more “directive” in their care and that immunizations should be better integrated into routine practice.

Jody Lanard, MD, a retired risk communication consultant who spent many years working with the World Health Organization on disease outbreak communications, said in an interview that this disconnect between physician and patient reports “was really jarring. And it’s actionable!”

She offered several practical suggestions. For one, she said, “the messaging to the specialists has to be very, very empathic. We know you’re already overburdened. And here we’re asking you to do something that you think of as somebody else’s job.” But if your patient gets flu, then your job as the cardiologist or endocrinologist will become more complicated and time-consuming. So getting the patients vaccinated will be a good investment and will make your job easier.

Because of the disparity in patient and physician reports, Dr. Lanard suggested implementing a “feedback mechanism where they [the health care providers] give out the prescription, and then the office calls [the patient] to see if they’ve gotten the shot or not. Because that way it will help correct the mismatch between them thinking that they told the patient and the patient not hearing it.”

Asked about why there might be a big gap between what physicians report they said and what patients heard, Dr. Lanard explained that “physicians often communicate in [a manner] sort of like a checklist. And the patients are focused on one or two things that are high in their minds. And the physician was mentioning some things that are on a separate topic that are not on a patient’s list and it goes right past them.”

Dr. Lanard recommended brief storytelling instead of checklists. For example: “I’ve been treating your diabetes for 10 years. During this last flu season, several of my diabetic patients had a really hard time when they caught the flu. So now I’m trying harder to remember to remind you to get your flu shots.”

She urged HCPs to “make it more personal ... but it can still be scripted in advance as part of something that [you’re] remembering to do during the check.” She added that their professional associations may be able to send them suggested language they can adapt.

Finally, Dr. Lanard cautioned about vaccine myths. “The word myth is so insulting. It’s basically a word that sends the signal that you’re an idiot.”

She advised specialists to avoid the word “myth,” which will make the person defensive. Instead, say something like, “A lot of people, even some of my own family members, think the flu vaccine gives you the flu. ... But it doesn’t. And then you go into the reality.”

Dr. Lanard suggested that specialists implement the follow-up calls and close the feedback loop, saying: “If they did the survey a few years later, I bet that gap would narrow.”

Dr. Schaffner and Dr. Lanard disclosed no relevant financial relationships.

A single dose of human papillomavirus (HPV) vaccine was highly effective at preventing oncogenic infection, rivaling the protection offered by multidose regimens, according to results from the KEN SHE trial, based in Kenya.

The findings, published on the preprint server Research Square and presented Nov. 17 at the 34th International Papillomavirus Conference in Toronto, bring “renewed energy to the push to make cervical cancer the first cancer to be wiped out globally,” according to co–principal investigator Ruanne V. Barnabas, PhD, a professor of global health at the University of Washington, Seattle.

Decision-makers will consider these findings, which have not yet been peer-reviewed, along with other evidence to determine if dosing-schedule changes are warranted, she told this news organization.

In a press release, Samuel Kariuki, PhD, acting director general, Kenya Medical Research Institute, who was not involved in the research, called the findings a “game changer” that could “substantially reduce the incidence of HPV-attributable cervical cancer.”

Between 2018 and 2019, Dr. Barnabas and her colleagues enrolled 2,275 sexually active, HPV-vaccine–naive women in Kenya in their study. The women, 15-20 years of age, were randomly assigned to receive a bivalent vaccine (HPV 16/18), a nonavalent vaccine (HPV 16/18/31/33/45/52/58/6/11), or a vaccine against meningococcal meningitis.

Most participants (57%) were between 15 and 17 years of age, and 61% reported one lifetime sexual partner. The women underwent genital and cervical swabs at enrollment to test for HPV DNA and had blood drawn to test for antibodies. During 18 months of follow-up, they had cervical swabs every 6 months and a vaginal swab at 3 months to test for HPV DNA.

The researchers detected 38 persistent HPV 16/18 infections in women who had tested negative for HPV 16/18 antibodies at enrollment and for HPV 16/18 DNA at enrollment and month 3 – one in each of the HPV-vaccine groups and 36 in the meningococcal group. This infection rate corresponded to a vaccine efficacy of 97.5% (P < .001) against HPV 16/18 for both the bivalent and nonavalent vaccines, which is “comparable to that seen in multidose vaccine trials,” the researchers write.

Among women negative for HPV 16/18/31/33/45/52/58 at the beginning of the trial, 33 had persistent infections: four in the nonavalent vaccine group and 29 in the meningococcal group, demonstrating an efficacy of 89% (P < .001) against all seven oncogenic strains contained in the vaccine.

Even if women tested positive for one strain of HPV, the vaccine protected them from other strains of the virus, the investigators noted.

Serious adverse events occurred in 4.5%-5.2% of participants across the study arms.

The KEN SHE trial comes 15 years after the U.S. Food and Drug Administration approved the first HPV vaccine – Merck’s Gardasil. Two others, Cervarix and Gardasil-9, have since been approved, but cost and supply issues have inhibited coverage, particularly in areas where the cervical cancer burden is high, the researchers noted.

Recent data indicate that just 15% of girls globally are vaccinated against HPV, but a single-dose vaccine would “simplify logistics and decrease costs,” thereby improving the chances of reaching the World Health Organization goal of vaccinating 90% of 15-year-old girls against HPV by 2030, Dr. Barnabas said in a press release about the trial.

Co–principal investigator Nelly Mugo, MBChB, MPH, senior principal clinical research scientist with the Center for Clinical Research at the Kenya Medical Research Institute in Nairobi, further emphasized the importance of the findings, noting in the press release that the “trial brings new energy to the elimination of cervical cancer. It brings great hope to the women living in countries like Kenya, who have a high burden of the disease.”

Dr. Mugo is also an associate research professor of global health at the University of Washington, Seattle.

Dr. Barnabas said women have been given multiple doses of the HPV vaccine because of “gaps in evidence for the effectiveness of a single-dose vaccine and concerns about clinically meaningful differences in efficacy.

“Observational data suggested that the single-dose HPV vaccine could have good efficacy, but because the data were not from randomized trials, that could have been from chance,” she explained, noting, however, that “sufficient evidence supported the decrease in doses from three to two doses for girls 15 years of age and younger.”

Going forward, the researchers will conduct immunobridging studies to other populations and will continue follow-up to assess the durability of single-dose efficacy, Dr. Barnabas said.

“The results from the KEN SHE trial support the use of single-dose HPV vaccination to increase access and coverage,” she concluded.

The KEN SHE trial was funded by the Bill & Melinda Gates Foundation (BMGF). Dr. Barnabas reports grants from BMGF and grants from King K. Holmes Professorship in STDs and AIDS during the conduct of the study, and grants from BMGF, National Institutes of Health, and manuscript and abstract writing support from Regeneron Pharmaceuticals outside the submitted work.

The researchers detected 38 persistent HPV 16/18 infections in women who had tested negative for HPV 16/18 antibodies at enrollment and for HPV 16/18 DNA at enrollment and month 3 – one in each of the HPV-vaccine groups and 36 in the meningococcal group. This infection rate corresponded to a vaccine efficacy of 97.5% (P < .001) against HPV 16/18 for both the bivalent and nonavalent vaccines, which is “comparable to that seen in multidose vaccine trials,” the researchers write.

Among women negative for HPV 16/18/31/33/45/52/58 at the beginning of the trial, 33 had persistent infections: four in the nonavalent vaccine group and 29 in the meningococcal group, demonstrating an efficacy of 89% (P < .001) against all seven oncogenic strains contained in the vaccine.

Even if women tested positive for one strain of HPV, the vaccine protected them from other strains of the virus, the investigators noted.

Serious adverse events occurred in 4.5%-5.2% of participants across the study arms.

The KEN SHE trial comes 15 years after the U.S. Food and Drug Administration approved the first HPV vaccine – Merck’s Gardasil. Two others, Cervarix and Gardasil-9, have since been approved, but cost and supply issues have inhibited coverage, particularly in areas where the cervical cancer burden is high, the researchers noted.

Recent data indicate that just 15% of girls globally are vaccinated against HPV, but a single-dose vaccine would “simplify logistics and decrease costs,” thereby improving the chances of reaching the World Health Organization goal of vaccinating 90% of 15-year-old girls against HPV by 2030, Dr. Barnabas said in a press release about the trial.

Co–principal investigator Nelly Mugo, MBChB, MPH, senior principal clinical research scientist with the Center for Clinical Research at the Kenya Medical Research Institute in Nairobi, further emphasized the importance of the findings, noting in the press release that the “trial brings new energy to the elimination of cervical cancer. It brings great hope to the women living in countries like Kenya, who have a high burden of the disease.”

Dr. Mugo is also an associate research professor of global health at the University of Washington, Seattle.

Dr. Barnabas said women have been given multiple doses of the HPV vaccine because of “gaps in evidence for the effectiveness of a single-dose vaccine and concerns about clinically meaningful differences in efficacy.

“Observational data suggested that the single-dose HPV vaccine could have good efficacy, but because the data were not from randomized trials, that could have been from chance,” she explained, noting, however, that “sufficient evidence supported the decrease in doses from three to two doses for girls 15 years of age and younger.”

Going forward, the researchers will conduct immunobridging studies to other populations and will continue follow-up to assess the durability of single-dose efficacy, Dr. Barnabas said.

“The results from the KEN SHE trial support the use of single-dose HPV vaccination to increase access and coverage,” she concluded.

The KEN SHE trial was funded by the Bill & Melinda Gates Foundation (BMGF). Dr. Barnabas reports grants from BMGF and grants from King K. Holmes Professorship in STDs and AIDS during the conduct of the study, and grants from BMGF, National Institutes of Health, and manuscript and abstract writing support from Regeneron Pharmaceuticals outside the submitted work.

A single dose of human papillomavirus (HPV) vaccine was highly effective at preventing oncogenic infection, rivaling the protection offered by multidose regimens, according to results from the KEN SHE trial, based in Kenya.

The findings, published on the preprint server Research Square and presented Nov. 17 at the 34th International Papillomavirus Conference in Toronto, bring “renewed energy to the push to make cervical cancer the first cancer to be wiped out globally,” according to co–principal investigator Ruanne V. Barnabas, PhD, a professor of global health at the University of Washington, Seattle.

Decision-makers will consider these findings, which have not yet been peer-reviewed, along with other evidence to determine if dosing-schedule changes are warranted, she told this news organization.

In a press release, Samuel Kariuki, PhD, acting director general, Kenya Medical Research Institute, who was not involved in the research, called the findings a “game changer” that could “substantially reduce the incidence of HPV-attributable cervical cancer.”

Between 2018 and 2019, Dr. Barnabas and her colleagues enrolled 2,275 sexually active, HPV-vaccine–naive women in Kenya in their study. The women, 15-20 years of age, were randomly assigned to receive a bivalent vaccine (HPV 16/18), a nonavalent vaccine (HPV 16/18/31/33/45/52/58/6/11), or a vaccine against meningococcal meningitis.

Most participants (57%) were between 15 and 17 years of age, and 61% reported one lifetime sexual partner. The women underwent genital and cervical swabs at enrollment to test for HPV DNA and had blood drawn to test for antibodies. During 18 months of follow-up, they had cervical swabs every 6 months and a vaginal swab at 3 months to test for HPV DNA.

The researchers detected 38 persistent HPV 16/18 infections in women who had tested negative for HPV 16/18 antibodies at enrollment and for HPV 16/18 DNA at enrollment and month 3 – one in each of the HPV-vaccine groups and 36 in the meningococcal group.

Children and adolescents with poorly controlled asthma were three to six times more likely to be hospitalized with COVID-19 infections, based on data from a national study of more than 750,000 children in Scotland.

Although the majority of COVID-19 cases in children have been mild, some children require hospitalization, wrote Ting Shi, PhD, of the University of Edinburgh (Scotland) and colleagues.

Vaccination policies to potentially reduce infection and hospitalization of children remain inconsistent, the researchers said. Identifying which school-age children would derive the greatest benefit from vaccination “could help to reduce the risk of infection and consequently the need for children to have time off school; and might also reduce the risk of spread of SARS-CoV-2 within schools and households,” but the potential benefits of vaccination for children with asthma in particular have not been well studied, they wrote.

The United Kingdom’s Joint Commission on Vaccination and Immunisation commissioned research on the rates of hospitalization among children with poorly controlled asthma. In a national incidence cohort study published in The Lancet Respiratory Medicine, the researchers reviewed data from all children aged 5-17 years in Scotland who were enrolled in the linked dataset of Early Pandemic Evaluation and Enhanced Surveillance of COVID-19 (EAVE II). The total number of children in the dataset was 752,867, and 63,463 (8.4%) of these had diagnosed asthma. Among the children with asthma, 4,339 (6.8%) had confirmed COVID-19 infections between March 1, 2020, and July 27, 2021. A total of 67 infected children were hospitalized. Of the 689,404 children without asthma, 40,231 (5.8%) had confirmed COVID-19 infections, and 382 (0.9%) of these children were hospitalized.

Overall, hospital admission rates for COVID-19 were significantly higher among children with asthma, compared to those without asthma (adjusted hazard ratio, 1.49), and the rates increased among children with poorly controlled asthma.

The researchers used previous hospital admission for asthma as a measure of uncontrolled asthma, and found that hospitalization was at least six times as likely for children with poorly controlled asthma, compared with those with no asthma (aHR, 6.40), although children with well-controlled asthma also had an increased risk of hospitalization, compared with those with no asthma (aHR, 1.36).

When the researchers used oral corticosteroid prescriptions as an indicator of uncontrolled asthma, the adjusted hazard ratios were 3.38, 3.53, 1.52, and 1.34 for children with prescribed corticosteroid courses of three or more, two, one, and none, respectively, compared with children with no asthma.

These hazard ratios remained significant after controlling for factors including age, sex, socioeconomic status, comorbidity, and previous hospital admission, the researchers wrote.

In an age-based analysis, results were similar for children aged 12-17 years, but in children aged 5-11 years, the hospitalization risk decreased for those with one course of corticosteroids and reached the highest rate for those with three or more courses, rather than two courses.

The study findings were limited by several factors including the relatively small numbers of COVID-19 hospitalizations, ICU admissions, and deaths in children with asthma, the researchers noted. Other limitations include potential changes in asthma control over the study period, and lack of data on certain confounders such as tobacco use, unsuitable housing, and ethnicity, they noted. However, the results were strengthened by the use of a large, national dataset, and access to electronic health records, they said.

The findings reflect data from previous studies suggesting increased risk of hospitalization for patients with respiratory illness who develop COVID-19 infections, the researchers wrote.

The results emphasize the importance of good asthma control to protect children from severe COVID-19, and careful monitoring of children with poorly controlled asthma who do become infected, they added.

“The findings from this linkage of multiple data sources have helped inform the prioritisation of school-aged children with poorly controlled asthma for vaccines,” they concluded.
 

Findings support value of vaccination for children with asthma

“Pediatricians see many children who suffer from asthma, and although one could assume that these children would have more serious consequences from contracting COVID-19, the current study examines a large database in a way not possible in the United States to address the severity question,” said Suzanne C. Boulter, MD, of the Geisel School of Medicine at Dartmouth, Hanover, N.H. “The authors used prior hospitalization rate or two prescriptions for oral corticosteroids as markers of asthma severity prior to the onset of COVID-19 in Scotland, and they collected retrospective data for 16 months of the pandemic through July of 2021, showing a significant increase in hospitalization for those children,” she said. Dr. Boulter said she was not surprised by this finding, given the impact of COVID-19 on the respiratory system.

“Pediatricians have found significant challenges from some groups of parents when discussing the indications and need for vaccination in their patients,” said Dr. Boulter. “Having this data on the increased risk of morbidity and mortality in children with asthma might help parents who are uncertain about the risk/benefit ratio of the vaccine make their decision,” she said.

Dr. Boulter said she hoped that additional studies will yield ongoing information about hospitalization rates for COVID-19 not only about asthma, but also other diagnoses affecting children in the United States and worldwide.

“It would also be important to see a breakdown of ethnic factors and adverse childhood experiences and how they relate to hospitalization and death from COVID-19,” Dr. Boulter said.

“The results of this study are not surprising, as we have known for a long time that children with severe asthma are more susceptible to severe respiratory viruses,” Francis E. Rushton, MD, a pediatrician in Beaufort, S.C., said in an interview. “But the study is still important, as it helps us determine which children are most urgently in need of protection from COVID-19 in any of its forms,” he emphasized. In particular, the current study underlines the importance of vaccinating children with unstable asthma, Dr. Rushton said.

Going forward, “it would be interesting to do additional studies looking at other markers for poor asthma control that could guide our vaccine efforts so that they are focused on those most at risk,” he added.

The study was supported by the UK Research and Innovation (Medical Research Council), Research and Innovation Industrial Strategy Challenge Fund, Health Data Research UK, and the Scottish Government. Lead author Dr. Shi had no financial conflicts to disclose. Dr. Rushton and Dr. Boulter had no financial conflicts to disclose, but each serves on the Editorial Advisory Board of Pediatric News.

Two different studies have found that, provided young females are immunized with the human papilloma virus (HPV) vaccine at a young enough age, both the incidence of and mortality from cervical cancer can be dramatically curtailed, data from the United Kingdom and to a lesser extent, the United States indicate.

In the U.K. study, published online in The Lancet, researchers showed that the national vaccination program against HPV, initiated in England in 2008, has all but eradicated cervical cancer and cervical intraepithelial neoplasia (CIN3) in young girls who received the vaccine at the age of 12 and 13 years (school year 8) prior to their sexual debut.

In this age group, cervical cancer rates were 87% lower than rates among previously nonvaccinated generations, while CIN3 rates were reduced by 97%, as researchers report. “It’s been incredible to see the impact of HPV vaccination, and now we can prove it prevented hundreds of women from developing cancer in England,” senior author Peter Sasieni, MD, King’s College London, said in a statement. “To see the real-life impact of the vaccine has been truly rewarding,” he added.

“This study provides the first direct evidence of the impact of the UK HPV vaccination campaign on cervical cancer incidence, showing a large reduction in cervical cancer rates in vaccinated cohorts,” Kate Soldan, MD, UK Health Security Agency, London, said in the same statement.

“This represents an important step forward in cervical cancer prevention, and we hope that these new results encourage uptake as the success of the vaccination programme relies not only on the efficacy of the vaccine but also the proportion of the population vaccinated,” she added.

Vanessa Saliba, MD, a consultant epidemiologist for the UK Health Security Agency, agreed, adding that “these remarkable findings confirm that the HPV vaccine saves lives by dramatically reducing cervical cancer rates among women.”

“This reminds us that vaccines are one of the most important tools we have to help us live longer, healthier lives,” she reemphasized.
 

British HPV program

When initiated in 2008, the national HPV vaccination program used the bivalent, Cervarix vaccine against HPV 16 and 18. As researchers noted, these two HPV types are responsible for 70%-80% of all cervical cancers in England.

However, in 2012, the program switched to the quadrivalent HPV vaccine (Gardasil) which is also effective against two additional HPV types, 6 and 11, both of which cause genital warts. The program also originally recommended the three-dose regimen for both HPV vaccines.

Now, only two doses of the vaccine are given to girls under the age of 15 even though it has been shown that a single dose of the HPV vaccine provides good protection against persistent infection, with efficacy rates that are similar to that of three doses, as the authors point out.

Among the cohort eligible for vaccination at 12 or 13 years of age, 89% received at least one dose of the HPV vaccine while 85% of the same age group received all three shots.
 

Cancer registry

Data from a population-based cancer registry was used to estimate the early effect of the bivalent HPV program on the incidence of cervical cancer and CIN3 in England between January 2006 and June 2019. During the study interval, there were 27,946 diagnoses of cervical cancer and 318,058 diagnoses of CIN3, lead author Milena Falcaro, MD, King’s College London, and colleagues report. Participants were then analyzed separately according to their age at the time of vaccination and the incidence rates calculated for both cervical cancer and CIN3 in the three separate groups.

For slightly older girls who received the vaccine between 14 and 16 years of age (school year 10-11), cervical cancer was reduced by 62% while CIN3 rates were reduced by 75%. For those who received the vaccine between 16 and 18 years of age (school year 12-13), cervical cancer rates were reduced by 34% while CIN3 rates were reduced by 39%, study authors add.

Indeed, the authors estimate that by June 2019 there were approximately 450 fewer cases of cervical cancer and 17,200 fewer cases of CIN3 than would otherwise have been expected in the vaccinated population in England.

The authors acknowledge that cervical cancer is rare in young women and vaccinated populations are still young. For example, the youngest recipients would have been immunized at the age of 12 in 2008 and would still be only 23 years old in 2019 when the study ended.

Thus, the authors emphasize that, because the vaccinated populations are still young, it’s too early to assess the full effect of HPV vaccination on cervical cancer rates.

Asked to comment on the study, Maurice Markman, MD, president, Medicine and Science Cancer Treatment Centers of America, pointed out that results from the British study are very similar to those from a Swedish study assessing the effect of the quadrivalent vaccine alone.

“You can put any superlatives you want in here, but these are stunningly positive results,” Dr. Markman said in an interview. As an oncologist who has been treating cervical cancer for 40 years – particularly advanced cervical cancer – “I can tell you this is one of the most devastating diseases to women, and the ability to eliminate this cancer with something as simple as a vaccine is the goal of cancer therapy, and it’s been remarkably successful,” he stressed.
 

Editorial commentary

Commenting on the findings, editorialists Maggie Cruickshank, MD, University of Aberdeen (Scotland), and Mihaela Grigore, MD, University of Medicine and Pharmacy, Lasi, Romania, point out that published reports evaluating the effect of HPV vaccination on cervical cancer rates have been scarce until now.

“The most important issue, besides the availability of the vaccine ... is the education of the population to accept vaccination because a high rate of immunization is a key element of success,” they emphasize. “Even in a wealthy country such as England with free access to HPV immunization, uptake has not reached the 90% vaccination target of girls aged 15 years set by the WHO [World Health Organization],” the editorialists add.

Dr. Cruickshank and Dr. Grigore also suggest that the effect HPV vaccination is having on cervical cancer rates as shown in this study should also stimulate vaccination programs in low- and middle-income countries where cervical cancer is a far greater public health issue than it is in countries with established systems of vaccination and screening.
 

HPV vaccination in the United States

The HPV vaccination program is similarly reducing the incidence of and mortality from cervical cancer among younger women in the United States who are most likely to have received the vaccine. As reported by lead author, Justin Barnes, MD, Washington University, St. Louis, the incidence of cervical cancer dropped by 37.7% from 2001 through 2005 to 2010 through 2017 in girls and young women between 15 and 24 years of age.

The U.S. study was published online in JAMA Pediatrics.

“HPV vaccine coverage in the U.S. has improved over the last few years although it was quite poor for many years,” senior author of the U.K. study, Peter Sasieni, MD, King’s College London, said in an interview. “Thus, one would anticipate a lower impact on the population in the U.S., because vaccine uptake, particularly in those aged 11-14 years was so much lower than it was in the U.K.,” he noted.
 

SEER databases

National age-adjusted cervical cancer incidence and mortality data from January 2001 through December 2017 for women and girls between 15 and 39 years of age were obtained from the combined Surveillance, Epidemiology, and End Results as well as the National Program of Cancer Registries databases. Mortality data was obtained from the National Center for Health Statistics.

Investigators then compared percentage changes in the incidence of and mortality from cervical cancer from January 2001 through December 2005 during the prevaccination years to that observed between January 2010 through December 2017 during the postvaccination years. They also compared incidence and mortality rates in three different cohorts: females between 15 and 24 years of age, those between 25 and 29 years of age, and those between 30 and 39 years of age.

“The older two groups were included as comparison, given their low vaccination rates,” the authors explained. Results showed that, during the same study interval from 2001 through 2005 to 2010 through 2017, the incidence of cervical cancer dropped by only 16.1% in women between 25 and 29 years of age and by only 8% for women between 30 and 39 years of age, the investigators report.

Reductions in mortality from cervical cancer were only strikingly so in the youngest age group of females between 15 and 24 years of age, among whom there was a 43.3% reduction in mortality from 2001-2005 to 2010-2017, as Dr. Barnes and colleagues note.

This pattern changed substantially in women between the ages of 25 and 29, among whom there was a 4.3% increase in mortality from cervical cancer during the same study interval and a small, 4.7% reduction among women between 30 and 39 years of age, investigators add. In actual numbers, mortality rates from cervical cancer were very low at only 0.6 per 100,000 in females between 15 and 24 years of age.

This compared to a mortality rate of 0.57 per 100,000 in women between 25 and 29 years of age and 1.89 per 100,000 in the oldest age group. “These nationwide data showed decreased cervical cancer incidence and mortality among women and girls aged 15-24 years after HPV vaccine introduction,” Dr. Barnes notes.

“Thus, the current study adds to knowledge by quantitatively comparing changes in cervical cancer incidence by age-based vaccine eligibility and providing suggestive evidence for vaccine-associated decreases in cervical cancer mortality,” investigators add.

However, as the authors also point out, while the reduction in mortality from cervical cancer associated with HPV vaccination may translate to older age groups as HPV-vaccinated cohorts age, “the number of deaths and hence the number of potentially averted deaths in young women and girls was small,” they caution, “and efforts to further improve vaccination uptake remain important.”

None of the authors or the editorialists had any conflicts of interest to declare.

Two different studies have found that, provided young females are immunized with the human papilloma virus (HPV) vaccine at a young enough age, both the incidence of and mortality from cervical cancer can be dramatically curtailed, data from the United Kingdom and to a lesser extent, the United States indicate.

In the U.K. study, published online in The Lancet, researchers showed that the national vaccination program against HPV, initiated in England in 2008, has all but eradicated cervical cancer and cervical intraepithelial neoplasia (CIN3) in young girls who received the vaccine at the age of 12 and 13 years (school year 8) prior to their sexual debut.

In this age group, cervical cancer rates were 87% lower than rates among previously nonvaccinated generations, while CIN3 rates were reduced by 97%, as researchers report. “It’s been incredible to see the impact of HPV vaccination, and now we can prove it prevented hundreds of women from developing cancer in England,” senior author Peter Sasieni, MD, King’s College London, said in a statement. “To see the real-life impact of the vaccine has been truly rewarding,” he added.

“This study provides the first direct evidence of the impact of the UK HPV vaccination campaign on cervical cancer incidence, showing a large reduction in cervical cancer rates in vaccinated cohorts,” Kate Soldan, MD, UK Health Security Agency, London, said in the same statement.

“This represents an important step forward in cervical cancer prevention, and we hope that these new results encourage uptake as the success of the vaccination programme relies not only on the efficacy of the vaccine but also the proportion of the population vaccinated,” she added.

Vanessa Saliba, MD, a consultant epidemiologist for the UK Health Security Agency, agreed, adding that “these remarkable findings confirm that the HPV vaccine saves lives by dramatically reducing cervical cancer rates among women.”

“This reminds us that vaccines are one of the most important tools we have to help us live longer, healthier lives,” she reemphasized.
 

British HPV program

When initiated in 2008, the national HPV vaccination program used the bivalent, Cervarix vaccine against HPV 16 and 18. As researchers noted, these two HPV types are responsible for 70%-80% of all cervical cancers in England.

However, in 2012, the program switched to the quadrivalent HPV vaccine (Gardasil) which is also effective against two additional HPV types, 6 and 11, both of which cause genital warts. The program also originally recommended the three-dose regimen for both HPV vaccines.

Now, only two doses of the vaccine are given to girls under the age of 15 even though it has been shown that a single dose of the HPV vaccine provides good protection against persistent infection, with efficacy rates that are similar to that of three doses, as the authors point out.

Among the cohort eligible for vaccination at 12 or 13 years of age, 89% received at least one dose of the HPV vaccine while 85% of the same age group received all three shots.
 

Cancer registry

Data from a population-based cancer registry was used to estimate the early effect of the bivalent HPV program on the incidence of cervical cancer and CIN3 in England between January 2006 and June 2019. During the study interval, there were 27,946 diagnoses of cervical cancer and 318,058 diagnoses of CIN3, lead author Milena Falcaro, MD, King’s College London, and colleagues report. Participants were then analyzed separately according to their age at the time of vaccination and the incidence rates calculated for both cervical cancer and CIN3 in the three separate groups.

For slightly older girls who received the vaccine between 14 and 16 years of age (school year 10-11), cervical cancer was reduced by 62% while CIN3 rates were reduced by 75%. For those who received the vaccine between 16 and 18 years of age (school year 12-13), cervical cancer rates were reduced by 34% while CIN3 rates were reduced by 39%, study authors add.

Indeed, the authors estimate that by June 2019 there were approximately 450 fewer cases of cervical cancer and 17,200 fewer cases of CIN3 than would otherwise have been expected in the vaccinated population in England.

The authors acknowledge that cervical cancer is rare in young women and vaccinated populations are still young. For example, the youngest recipients would have been immunized at the age of 12 in 2008 and would still be only 23 years old in 2019 when the study ended.

Thus, the authors emphasize that, because the vaccinated populations are still young, it’s too early to assess the full effect of HPV vaccination on cervical cancer rates.

Asked to comment on the study, Maurice Markman, MD, president, Medicine and Science Cancer Treatment Centers of America, pointed out that results from the British study are very similar to those from a Swedish study assessing the effect of the quadrivalent vaccine alone.

“You can put any superlatives you want in here, but these are stunningly positive results,” Dr. Markman said in an interview. As an oncologist who has been treating cervical cancer for 40 years – particularly advanced cervical cancer – “I can tell you this is one of the most devastating diseases to women, and the ability to eliminate this cancer with something as simple as a vaccine is the goal of cancer therapy, and it’s been remarkably successful,” he stressed.
 

Editorial commentary

Commenting on the findings, editorialists Maggie Cruickshank, MD, University of Aberdeen (Scotland), and Mihaela Grigore, MD, University of Medicine and Pharmacy, Lasi, Romania, point out that published reports evaluating the effect of HPV vaccination on cervical cancer rates have been scarce until now.

“The most important issue, besides the availability of the vaccine ... is the education of the population to accept vaccination because a high rate of immunization is a key element of success,” they emphasize. “Even in a wealthy country such as England with free access to HPV immunization, uptake has not reached the 90% vaccination target of girls aged 15 years set by the WHO [World Health Organization],” the editorialists add.

Dr. Cruickshank and Dr. Grigore also suggest that the effect HPV vaccination is having on cervical cancer rates as shown in this study should also stimulate vaccination programs in low- and middle-income countries where cervical cancer is a far greater public health issue than it is in countries with established systems of vaccination and screening.
 

HPV vaccination in the United States

The HPV vaccination program is similarly reducing the incidence of and mortality from cervical cancer among younger women in the United States who are most likely to have received the vaccine. As reported by lead author, Justin Barnes, MD, Washington University, St. Louis, the incidence of cervical cancer dropped by 37.7% from 2001 through 2005 to 2010 through 2017 in girls and young women between 15 and 24 years of age.

The Moderna CEO says existing COVID-19 vaccines will likely be less effective against the new Omicron variant.

“There is no world, I think, where [the effectiveness] is the same level … we had with Delta,” Stephane Bancel told the Financial Times .

“I think it’s going to be a material drop,” he said. “I just don’t know how much, because we need to wait for the data. But all the scientists I’ve talked to … are like, ‘This is not going to be good.’”

Vaccine companies are now studying whether the new Omicron variant could evade the current shots. Some data is expected in about 2 weeks.

Mr. Bancel said that if a new vaccine is needed, it could take several months to produce at scale. He estimated that Moderna could make billions of vaccine doses in 2022.

“[Moderna] and Pfizer cannot get a billion doses next week. The math doesn’t work,” he said. “But could we get the billion doses out by the summer? Sure.”

The news caused some panic on Nov. 30, prompting financial markets to fall sharply, according to Reuters. But the markets recovered after European officials gave a more reassuring outlook.

“Even if the new variant becomes more widespread, the vaccines we have will continue to provide protection,” Emer Cooke, executive director of the European Medicines Agency, told the European Parliament.

Mr. Cooke said the agency could approve new vaccines that target the Omicron variant within 3 to 4 months, if needed. Moderna and Pfizer have announced they are beginning to tailor a shot to address the Omicron variant in case the data shows they are necessary.

Also on Nov. 30, the European Centre for Disease Prevention and Control announced that 42 Omicron cases had been identified in 10 European Union countries, according to Reuters.

The cases were mild or had no symptoms, although they were found in younger people who may have mild or no symptoms anyway.

“For the assessment of whether [Omicron] escapes immunity, we still have to wait until investigations in the laboratories with [blood samples] from people who have recovered have been carried out,” Andrea Ammon, MD, chair of the agency, said during an online conference.

The University of Oxford, which developed a COVID-19 vaccine with AstraZeneca, said Nov. 30 that there’s no evidence that vaccines won’t prevent severe disease from the Omicron variant, according to Reuters.

“Despite the appearance of new variants over the past year, vaccines have continued to provide very high levels of protection against severe disease and there is no evidence so far that Omicron is any different,” the university said in a statement. “However, we have the necessary tools and processes in place for rapid development of an updated COVID-19 vaccine if it should be necessary.”

Human papillomavirus (HPV) vaccination helps prevent cervical cancer and saves lives, new nationwide data suggest.

The analysis adds to a growing body of evidence demonstrating vaccine-associated changes in cervical cancer incidence and mortality.

Previous data from the United Kingdom, published earlier in November, showed that cervical cancer rates were 87% lower among girls who received the HPV vaccine compared to previously unvaccinated generations. Based on the analysis, the authors concluded that the UK’s HPV immunization program “almost eliminated cervical cancer” in women born since September 1995.

The latest study, published Nov. 29 in JAMA Pediatrics , reports a 38% drop in cervical cancer incidence and a 43% decline in mortality among young women and girls after HPV vaccination was introduced in the United States.

“These results are encouraging,” Peter Sasieni, MD, of King’s College London, and senior author on the U.K. study, told this news organization in an email.

The difference in incidence rates between the U.K. and U.S. studies, Dr. Sasieni explained, is likely due to HPV vaccine coverage not expanding as significantly in the United States as it has in the United Kingdom, and “thus one would anticipate a lower impact on the population in the U.S.”

In the U.S. analysis, Justin Barnes, MD, a radiation oncology resident at Washington University, St. Louis, and colleagues examined cervical cancer incidence between January 2001 and December 2017 using Surveillance, Epidemiology, and End Results and National Program of Cancer Registries data as well as mortality data from the National Center for Health Statistics.

Dr. Barnes and colleagues then compared changes in cervical cancer incidence and mortality between prevaccination years (January 2001 to December 2005) and postvaccination years (January 2010 to December 2017) among three age cohorts – 15-24 years, 25-29 years, and 30-39 years.

“The older 2 groups were included as comparison, given their low vaccination rates,” Dr. Barnes and colleagues explained.

Results show that between the prevaccination and postvaccination periods, the incidence of cervical cancer dropped by 38% in the youngest cohort and by only 16% in the middle-aged group and 8% in the oldest cohort.

Women and girls in the youngest group saw a striking drop in mortality: a 43% decline, which translated to a mortality rate of 0.6 per 100,000.

On the other hand, the authors report a 4.7% decline in mortality in the oldest group and a 4.3% increase in mortality in the middle-aged group – translating to a mortality rate of 1.89 per 100,000 and 0.57 per 100,000, respectively.

Overall, “these nationwide data showed decreased cervical cancer incidence and mortality among women and girls aged 15-24 years after HPV vaccine introduction,” Dr. Barnes and colleagues wrote. The changes in cervical cancer incidence and mortality observed in the youngest age group “were greater than changes in those aged 25 to 29 years and 30 to 39 years, suggesting possible associations with HPV vaccination.”

This analysis lines up with previous evidence from U.S. epidemiologic data, which “have shown decreased cervical cancer incidence after vaccine implementation in women and girls aged 15 to 24 years but not older women.”

Although “the number of deaths and hence the number of potentially averted deaths in young women and girls was small,” the study adds to the current literature by “providing suggestive evidence for vaccine-associated decreases in cervical cancer mortality,” investigators concluded.

The authors have disclosed no relevant financial relationships.

Human papillomavirus (HPV) vaccination helps prevent cervical cancer and saves lives, new nationwide data suggest.

The analysis adds to a growing body of evidence demonstrating vaccine-associated changes in cervical cancer incidence and mortality.

Previous data from the United Kingdom, published earlier in November, showed that cervical cancer rates were 87% lower among girls who received the HPV vaccine compared to previously unvaccinated generations. Based on the analysis, the authors concluded that the UK’s HPV immunization program “almost eliminated cervical cancer” in women born since September 1995.

The latest study, published Nov. 29 in JAMA Pediatrics , reports a 38% drop in cervical cancer incidence and a 43% decline in mortality among young women and girls after HPV vaccination was introduced in the United States.

“These results are encouraging,” Peter Sasieni, MD, of King’s College London, and senior author on the U.K. study, told this news organization in an email.

The difference in incidence rates between the U.K. and U.S. studies, Dr. Sasieni explained, is likely due to HPV vaccine coverage not expanding as significantly in the United States as it has in the United Kingdom, and “thus one would anticipate a lower impact on the population in the U.S.”

In the U.S. analysis, Justin Barnes, MD, a radiation oncology resident at Washington University, St. Louis, and colleagues examined cervical cancer incidence between January 2001 and December 2017 using Surveillance, Epidemiology, and End Results and National Program of Cancer Registries data as well as mortality data from the National Center for Health Statistics.

Dr. Barnes and colleagues then compared changes in cervical cancer incidence and mortality between prevaccination years (January 2001 to December 2005) and postvaccination years (January 2010 to December 2017) among three age cohorts – 15-24 years, 25-29 years, and 30-39 years.

“The older 2 groups were included as comparison, given their low vaccination rates,” Dr. Barnes and colleagues explained.

Pfizer announced on Nov. 22 that its COVID-19 vaccine provided long-term protection against the virus in a late-stage clinical trial among adolescents ages 12-15.

A two-dose series was 100% effective against COVID-19, which was measured between 7 days and 4 months after the second dose.

“As the global health community works to increase the number of vaccinated people around the world, these additional data provide further confidence in our vaccine safety and effectiveness profile in adolescents,” Albert Bourla, PhD, chairman and CEO of Pfizer, said in a statement.

The clinical trial researchers found no serious safety concerns while following patients for 6 months. The adverse events were consistent with other clinical safety data for the vaccine, the company said.

Pfizer will incorporate the data into its submissions for full regulatory approval of the vaccine for ages 12-15 in the United States and worldwide.

The company will request clearance for a 30-mcg dose of the vaccines for ages 12 and older. The shot received FDA emergency use authorization for ages 12-15 in May and full approval for ages 16 and older in August.

The study included 2,228 clinical trial participants who were monitored between November 2020 and September 2021. There were 30 confirmed symptomatic cases of COVID-19 in the placebo group that didn’t receive the vaccine and 0 COVID-19 cases among the vaccinated group.

The efficacy was consistently high across gender, race, ethnicity, and health conditions, the company said.

“This is especially important as we see rates of COVID-19 climbing in this age group in some regions, while vaccine uptake has slowed,” Mr. Bourla said. “We look forward to sharing these data with the FDA and other regulators.”

Although the estimated annual number of measles deaths decreased 94% from 2000 to 2020, the COVID-19 pandemic took a toll on both measles vaccination and surveillance, according to a recent report in Morbidity and Mortality Weekly Report.

The number of World Health Organization member states that achieved more than 90% coverage with the first dose of the measles vaccine (MCV1) declined 37% from 2019 to 2020. In 2020, 23 million infants did not receive MCV1 through routine immunization services, and another 93 million were affected by the postponement of mass immunizations or supplementary immunization activities because of the pandemic. Also, endemic transmission was reestablished in nine countries that had previously eliminated measles.

But perhaps the most overlooked aspect of COVID-19 is its effect on surveillance.

“The entire COVID pandemic really put a lot of strain on the surveillance systems, not only for measles but for all vaccine-preventable disease, because there’s a lot of overlap in the staff who work for surveillance,” said Katrina Kretsinger, MD, a medical epidemiologist at the Centers for Disease Control and Prevention, who contributed to the MMWR report.

Because of the stress on the systems, a lot fewer specimens were tested, she said in an interview. And it’s not just measles that is at risk. This has had an impact on the Global Polio Eradication Initiative, which lost staff.

In addition, many vaccination campaigns “were postponed and curtailed throughout 2020,” Dr. Kretsinger said. The strengthening of surveillance systems – and immunization systems, more broadly – needs to be a priority.

“It’s not clear that the children who were missed during that year were subsequently caught up,” she explained. Having a “cohort of children who have missed measles vaccine creates the reservoir of susceptibility that will provide the nidus for the next big outbreak.”

Measles is the indicator disease. That could mean a resurgence of other vaccine-preventable diseases as well.

This report “was written by some of the world’s experts in measles, and it raises concerns about potential resurgence of measles,” said Walter Orenstein, MD, professor of medicine, epidemiology, global health, and pediatrics at Emory University, Atlanta. “Measles is sort of a canary in the coal mine. If you look at vaccine-preventable diseases, measles is probably the most contagious, so the herd-immunity threshold is highest. Usually on the order of 92%-94% immunity is needed to stop transmission.”

“Measles is the indicator disease,” he said in an interview. “That could mean a resurgence of other vaccine-preventable diseases as well.” Outbreaks don’t just affect the countries where infections are occurring, they “also affect our own domestic health security.”

“Some sort of periodic intensified routine immunization” would be helpful, said Dr. Kretsinger, who recommends “going through and selectively doing some sort of intensified efforts to catch children up early for the entire range of vaccines that they may have missed.”

“Some of these capture campaigns in areas that are thought to have the major problem would be very, very important,” agreed Dr. Orenstein. “A school entry check is one way of trying to look at kids, let’s say at 4-6 years of age, in schools around the world,” offering doses if they’re unvaccinated or inadequately vaccinated. “Another is to try to improve surveillance and try to understand if the cases are vaccine failure or failure to vaccinate.”

“Where the health systems are the most fragile is where those gaps will be the last to be filled, if they are at all, and where we have the basic concerns,” Dr. Kretsinger explained.

“Years ago, WHO recognized that vaccine hesitancy is a top global health threat,” said Dr. Orenstein. “People may not see these diseases so they don’t mean much to them. Since vaccines, we’re victims of our own success.” There’s also a lot of incorrect information circulating.

“We need to realize – and it’s been shown with COVID – that a decision not to vaccinate is not just a decision for your own child. It’s a community decision,” he pointed out. “It’s not my freedom to drive drunk, because not only do I put myself at risk, but others can’t control the car. We have speed limits and other examples where we restrict personal choice because it can adversely affect individuals.”

“My favorite line is vaccines don’t save lives, vaccinations save lives,” Dr. Orenstein said. “The vaccine dose that remains in the vial is 0% effective, no matter what the clinical trials show. And the issue, I think, is that we need to determine how to convince the hesitant to get confident enough to accept vaccination. For that, there is behavioral research; there’s a whole bunch of things that need to be supported. Just purchasing the vaccine doesn’t get it into the bodies.”

Dr. Kretsinger and Dr. Orenstein disclosed no relevant financial relationships .

A Medscape poll on clinicians’ confidence surrounding the COVID-19 vaccine for kids ages 5-11 showed significant hesitancy.

Among physician respondents who have children in that age group, 30% said they would not want their children to be vaccinated; 9% were unsure. For nurses/advanced practice registered nurses (APRNs), more (45%) said they did not want their kids to get the COVID-19 vaccine; 13% were unsure. Among pharmacists, 31% said they would not get them vaccinated and 9% were unsure.

Clinicians were more likely to want vaccinations for their kids 5-11 than were 510 consumers polled by WebMD at the same time. Overall, 49% of the consumers who had kids that age did not want them to get the COVID-19 vaccine.

On November 2, Centers for Disease Control and Prevention (CDC) Director Rochelle P. Walensky, MD, MPH, endorsed the CDC Advisory Committee on Immunization Practices’ recommendation that children 5-11 be vaccinated with the Pfizer-BioNTech pediatric vaccine. That decision expanded vaccine recommendations to about 28 million children in the United States.

The CDC states that, in clinical trials, the Pfizer vaccine had more than 90% efficacy in preventing laboratory-confirmed COVID-19 infection in children 5 to 15 years old, and that the immune response in children ages 5-15 equaled the immune response in people 16 to 25 years old.

The Medscape poll, fielded from November 3 to November 11, included 325 physicians, 793 nurses/APRNs, and 151 pharmacists.
 

How safe is the vaccine?

Clinicians were asked how confident they were that the vaccine is safe for that age group, and 66% of physicians, 52% of nurses/APRNs, and 66% of pharmacists said they were somewhat or very confident.

Among consumers overall in the WebMD poll, 56% said they were confident or somewhat confident that the vaccine is safe in that age group.

Among adolescents and young adults, rare cases of myocarditis and pericarditis in adolescents and young adults have been reported. According to the CDC, “[I]n one study, the risk of myocarditis after the second dose of Pfizer-BioNTech in the week following vaccination was around 54 cases per million doses administered to males ages 12-17 years.”

Known and potential benefits of COVID-19 vaccination outweigh the risks, including the possible risk for myocarditis or pericarditis, the CDC states.

Across clinician types, women edged out their male counterparts on confidence in the vaccine’ s safety: 71% vs 65% among physicians, 55% vs 45% among nurses/APRNs, and 68% vs 60% among pharmacists.

Among both physicians and nurses, younger physicians (under 45) tended to have greater confidence in the vaccine’ s safety: 72% vs 64% (physicians), 54% vs 51% (nurses/APRNs), and 71% vs 59% (pharmacists).

The difference in confidence was clear between vaccinated and unvaccinated physicians. All of the unvaccinated physicians who responded to the poll said they had no confidence in the vaccine for kids. Among unvaccinated nurses/APRNs, 2% were somewhat confident in the vaccine for kids under 12.
 

Knowledge about smaller dosage

The clinicians were asked about whether they were aware, before reading the poll question, that the Pfizer vaccine for children and the proposed Moderna vaccine for children in this age group (5-11) would have a different dosage.

The dose for kids 5-11 is 10 micrograms rather than 30 micrograms for people at least 12 years old. Children 5-11 receive a second dose 21 days or more after their first shot. The formulation comes with an orange cap, and a smaller needle is used.

Knowledge on the lower dose was highest among pharmacists (91% said they knew), followed by physicians (84%) and nurses (79%).

The poll also asked whether the COVID-19 vaccine should be added to the list of childhood immunizations. Responses varied widely and uncertainty was evident.

Notably, female physicians were more likely to say it should be added to the list of immunizations than were their male counterparts: 46% vs 35% (physicians), 26% vs 22% (nurses/APRNs), and 33% vs 30% (pharmacists).

The Medscape poll, fielded from November 3 to November 11, included 325 physicians, 793 nurses/APRNs, and 151 pharmacists.
 

How safe is the vaccine?

Clinicians were asked how confident they were that the vaccine is safe for that age group, and 66% of physicians, 52% of nurses/APRNs, and 66% of pharmacists said they were somewhat or very confident.

Among consumers overall in the WebMD poll, 56% said they were confident or somewhat confident that the vaccine is safe in that age group.

Among adolescents and young adults, rare cases of myocarditis and pericarditis in adolescents and young adults have been reported. According to the CDC, “[I]n one study, the risk of myocarditis after the second dose of Pfizer-BioNTech in the week following vaccination was around 54 cases per million doses administered to males ages 12-17 years.”

Known and potential benefits of COVID-19 vaccination outweigh the risks, including the possible risk for myocarditis or pericarditis, the CDC states.

Across clinician types, women edged out their male counterparts on confidence in the vaccine’ s safety: 71% vs 65% among physicians, 55% vs 45% among nurses/APRNs, and 68% vs 60% among pharmacists.

Among both physicians and nurses, younger physicians (under 45) tended to have greater confidence in the vaccine’ s safety: 72% vs 64% (physicians), 54% vs 51% (nurses/APRNs), and 71% vs 59% (pharmacists).

The difference in confidence was clear between vaccinated and unvaccinated physicians. All of the unvaccinated physicians who responded to the poll said they had no confidence in the vaccine for kids. Among unvaccinated nurses/APRNs, 2% were somewhat confident in the vaccine for kids under 12.
 

Knowledge about smaller dosage

The clinicians were asked about whether they were aware, before reading the poll question, that the Pfizer vaccine for children and the proposed Moderna vaccine for children in this age group (5-11) would have a different dosage.

The dose for kids 5-11 is 10 micrograms rather than 30 micrograms for people at least 12 years old. Children 5-11 receive a second dose 21 days or more after their first shot. The formulation comes with an orange cap, and a smaller needle is used.

Knowledge on the lower dose was highest among pharmacists (91% said they knew), followed by physicians (84%) and nurses (79%).

The poll also asked whether the COVID-19 vaccine should be added to the list of childhood immunizations. Responses varied widely and uncertainty was evident.

Notably, female physicians were more likely to say it should be added to the list of immunizations than were their male counterparts: 46% vs 35% (physicians), 26% vs 22% (nurses/APRNs), and 33% vs 30% (pharmacists).

A Medscape poll on clinicians’ confidence surrounding the COVID-19 vaccine for kids ages 5-11 showed significant hesitancy.

Among physician respondents who have children in that age group, 30% said they would not want their children to be vaccinated; 9% were unsure. For nurses/advanced practice registered nurses (APRNs), more (45%) said they did not want their kids to get the COVID-19 vaccine; 13% were unsure. Among pharmacists, 31% said they would not get them vaccinated and 9% were unsure.

Clinicians were more likely to want vaccinations for their kids 5-11 than were 510 consumers polled by WebMD at the same time. Overall, 49% of the consumers who had kids that age did not want them to get the COVID-19 vaccine.

On November 2, Centers for Disease Control and Prevention (CDC) Director Rochelle P. Walensky, MD, MPH, endorsed the CDC Advisory Committee on Immunization Practices’ recommendation that children 5-11 be vaccinated with the Pfizer-BioNTech pediatric vaccine. That decision expanded vaccine recommendations to about 28 million children in the United States.

The CDC states that, in clinical trials, the Pfizer vaccine had more than 90% efficacy in preventing laboratory-confirmed COVID-19 infection in children 5 to 15 years old, and that the immune response in children ages 5-15 equaled the immune response in people 16 to 25 years old.
