Prevention of Hepatitis A Virus Infection in the United States

The Advisory Committee on Immunization Practices recently published the first full update to hepatitis A vaccination recommendations in 14 years. Two new recommendations are: hepatitis A “catch-up” vaccination for all children and adolescents aged 2-18 years who have not previously received hepatitis A vaccine; and identification of HIV as a risk factor for hepatitis A infection and the recommendation for routine hepatitis A vaccination of all persons age 12 months and older with HIV infection.
