Background: The incidence of Hepatitis A (HAV) among the general population in the United States has decreased by over 95% since the introduction of HAV vaccination in 1995. However, 10% of all new HAV infections occur among me who have sex with men (MSM). However routine HAV is not part of standard of care for provision of PrEP services. Methods: Retrospective cohort analysis of MSM assessed for HIV prevention services between 1/1/2016 – 6/30/2017 to evaluate the rates of screening for anti-HAV seroprevalence and subsequent vaccination Results: HAV IgG was drawn on 96% (96/100) of the patients with 58% (56/96) of patients demonstrating serologic immunity. Of the 40 patients without evidence of immunity, 77% (29/40) returned for a subsequent visit, 48% (14/29) were provided HAV vaccination, and 29% (4/14) received at least two doses. Only 35% (14/40) patients without documented immunity received HAV vaccination. Conclusions: Visits for PrEP initiation and monitoring in MSM patients are potential opportunities for ensuring HAV vaccination among this high-risk patient population. Public health agencies could optimize HAV vaccination of the high risk MSM by incorporating HAV screening into national PrEP guidelines.
