HealthDay News — Hepatitis B vaccination should be administered to adults aged 19 to 59 years and to those aged 60 years or older with risk factors for hepatitis B, according to updated recommendations published in the Morbidity and Mortality Weekly Report.

Mark K. Weng, MD, from the Centers for Disease Control and Prevention (CDC) in Atlanta, and colleagues updated recommendations for Hepatitis B vaccination for adults based on a review and discussion of the relevant scientific evidence. The review was informed by 263 studies deemed eligible.

Approximately 50% of acute hepatitis B cases reported in 2019 occurred among adults aged 30 to 49 years and the number of cases of acute hepatitis B increased among adults aged 40 to 49 years and aged 50 to 59 years from 2011 to 2019, according to the researchers. In addition, hepatitis B vaccination coverage is low among adults aged 19 years and older. As a result, the Advisory Committee on Immunization Practices recommends that adults aged 19 to 59 years and those aged 60 years or older with risk factors should receive hepatitis B vaccines, and that those aged 60 years or older without risk factors should be offered vaccination and may receive vaccines. Those who have completed a hepatitis B vaccination series or with a history of hepatitis B infection should not receive additional vaccination, apart from cases where revaccination may be indicated.

“Universal adult HepB vaccination through age 59 years removes the need for risk factor screening and disclosure and could increase vaccination coverage and decrease hepatitis B cases,” the authors wrote.
