Prevalence of hepatitis A and B antibodies among enlisted accessions, Joint Base San Antonio-Lackland, 2023.

The Department of the Air Force performs universal antibody serology testing for hepatitis B surface antibody (anti-HBs) and hepatitis A immunoglobulin G (IgG anti-HAV) among enlisted recruits presenting to basic military training (BMT) at Joint Base San Antonio (JBSA)-Lackland. These results, along with previous vaccination records, if available at the time of accession, guide HBV and HAV vaccination during BMT. Data from January 1, 2023, through December 31, 2023, in the electronic health record, MHS-GENESIS, was used for this analysis. This analysis shows a much higher prevalence of HAV antibodies compared to HBV in the trainee population at JBSA-Lackland during 2023.
