Hepatitis B Virus Prevalence and Vaccination in Men Who Have Sex With Men in West Africa (CohMSM ANRS 12324-Expertise France).

ABSTRACT:

Background

Although men who have sex with men (MSM) are at high risk of hepatitis B virus (HBV) infection, they do not have access to vaccination in West Africa, which is a highly endemic region. We investigated HBV prevalence and associated factors, as well as acceptability and difficulties of vaccination in MSM enrolled in an operational research program in Burkina Faso, Côte d'Ivoire, Mali, and Togo.

Methods

We followed up 779 MSM in 2015-2018. Participants who were negative for both hepatitis B surface antigen (HBsAg) and antibodies (anti-HBs) at enrollment were offered HBV vaccination. Factors associated with HBV infection were identified using logistic regression models.

Results

Overall, HBV prevalence was 11.2% (95% confidence interval [CI], 9.0%-13.6%). It was
