Psychiatric patients who use drugs, alcohol, or tobacco and those who engage in high-risk sexual behaviors can be protected from acquiring viral infections such as hepatitis A and B, influenza, and human papillomavirus (HPV). The recently updated adult immunization schedule (Table)^1,2 from the Centers for Disease Control and Prevention’s Advisory Committee on Immunization Practices (ACIP) gives mental health professionals the opportunity to recognize risk and refer patients for vaccinations as part of preventive care. (see Related Resources) for a link to the complete CDC vaccination recommendations.

Hepatitis A and B. Substance abuse and high-risk sexual behaviors contribute to the high prevalence of comorbid alcohol-related liver disease and viral hepatitis among psychiatric patients. Individuals with chronic liver disease—regardless of its cause—should be screened for hepatitis A and B infection and, if negative, offered the appropriate vaccination series. Acute viral hepatitis in patients with pre-existing chronic hepatitis from any cause, such as alcohol abuse or hepatitis C, is associated with severe hepatic dysfunction and liver failure.³

Hepatitis B screening and vaccination is recommended for psychiatric populations that include clients of substance abuse treatment centers and institutions and daycare facilities for developmental disabilities, as well as IV drug users. Anyone who uses illegal drugs—injectable or noninjectable—should be vaccinated for hepatitis A.

Only individuals susceptible to hepatitis A and B should be vaccinated.³ To determine immune status for hepatitis B, serum tests for hepatitis B surface antigen (HepBsAg), hepatitis B surface antibody IgG (HepBsAb), and hepatitis B core antibody IgG (HepBcAb) are necessary to differentiate among patients who:

• are susceptible to infection
• had an infection that cleared
• have chronic active infection
• already have been vaccinated.

The hepatitis A IgG serum test determines a patient’s hepatitis A immune status. A negative result shows no previous infection, and the patient is eligible for vaccination. A positive result indicates previous infection meaning vaccination has no benefit.³

Influenza. Tobacco use and subsequent chronic pulmonary disease is an indication for annual influenza vaccination.⁴ Most individuals will receive the injectable, inactivated vaccine. The intranasal, live attenuated vaccine is reserved for nonpregnant adults age ≤49 without high-risk medical conditions and who are not in close contact with immunocompromised persons.¹

Pneumococcal and influenza vaccinations also are recommended for persons with chronic liver disease.¹ Consider recommending influenza, pneumococcal, varicella, and hepatitis B vaccinations for psychiatric patients in long-term care facilities.¹

HPV. Cervical cancer is highly associated with HPV, a sexually transmitted organism, and the HPV vaccine can effectively prevent infection and subsequent neoplasia. All women age ≤26 are eligible for the vaccine. Women with evidence of HPV infection—such as abnormal Pap smear, genital warts, or a positive HPV DNA test—are still eligible to receive the HPV vaccine because several viral strains cause disease.¹ Because mental health providers may treat otherwise medically healthy young people, including those who engage in high-risk behaviors, psychiatrists have an opportunity to refer for vaccinations individuals who may not consistently utilize primary care.

Immunity screening considerations. Vaccines for HPV, influenza, and pneumonia are recommended regardless of evidence of immunity or prior infection. Hepatitis A and B vaccines require a history of never having had the illness or laboratory evidence of a lack of immunity.
