Men Who Have Sex with Men and Viral Hepatitis
Men who have sex with men should be tested for hepatitis B and vaccinated against hepatitis A and hepatitis B.
Because men who have sex with men (MSM) have a high prevalence of hepatitis B, CDC recommends hepatitis B testing for MSM. However, hepatitis B testing is not a requirement for vaccination.
CDC and the Advisory Committee on Immunization Practices (ACIP) recommend hepatitis A and hepatitis B vaccination for men who have sex with men (MSM). The hepatitis A and hepatitis B vaccines can be given separately or as a combination vaccine using a recommended schedule. Adult vaccination rates are low and many men remain at risk for hepatitis A and hepatitis B.
MSM and Hepatitis A
Despite the availability of a safe and effective vaccine, Hepatitis A outbreaks among MSM have been reported frequently. Widespread outbreaks of hepatitis A are occurring across the U.S. and many are affecting gay and bisexual men. Since 1996, ACIP has recommended hepatitis A vaccination of MSM. Despite this longstanding recommendation, hepatitis A vaccination coverage among this population remains low, with vaccination coverage estimated at 25%–45% overall.
MSM and Hepatitis B
The hepatitis B vaccine is safe and effective, and both ACIP and CDC recommend routine hepatitis B vaccination for MSM. CDC also recommends hepatitis B testing for MSM because of the high prevalence of hepatitis B in this population and the population’s ongoing risk for infection. Hepatitis B testing for MSM is recommended as a component of prevaccination testing for these adults and consists of testing for HBsAg, anti-HBs, and anti-HBc. However, serologic testing should not be a barrier to vaccination of susceptible persons, especially in populations that are difficult to access. The first dose of hepatitis B vaccine should be administered during the same medical visit immediately after blood is collected for serologic testing. Hepatitis B testing of MSM is not a requirement for vaccination, and in settings where testing is not feasible, vaccination should continue without testing.
