VHA HAV Immunization Guidelines

The Veterans Health Administration recommends HAV immunization (unless contraindicated) for previously unvaccinated adults who are at increased risk of contracting HAV infection and for any other adult who is seeking protection from HAV infection. High risk groups include:

  • Persons traveling to or working in countries that have high or intermediate endemicity of infection

  • Men who have sex with men

  • Users of infection or noninjection illicit drugs

  • Persons with chronic liver disease (includes individuals with HBV infection, HCV infection, cirrhosis, liver fibrosis, clinical signs consistent with chronic liver disease, awaiting liver transplantation, or post-liver transplantation)

  • Persons with clotting factor disorders

  • Persons who work with HAV-infected primates or with HAV in a research laboratory setting

  • Unimmunized persons who previously had HAV infectiona

Since these individuals may not be immune to HAV, it is recommended that they be given the first dose in the 2-dose series, tested for HAV antibodies during the same visit, and be given a second dose of HAV vaccine if they are found to be nonimmune.
