The Chapman Training Annex is a part of Joint Base San Antonio.
The basic training facility for the Air Force in San Antonio, Texas, is experiencing a flu outbreak following the end of mandatory vaccination for all service members.
As of Wednesday, there are at least 159 known cases among recruits and two hospitalizations among recruits at Lackland Air Force Base at Joint Base San Antonio, two sources familiar with the matter told ABC News.
Previously, the flu vaccine was mandatory, but the new policy is in line with a previous change of making the COVID-19 vaccine optional.
The sources told ABC News that there is 40% flu vaccination rate among recruits at the San Antonio base since the mandate was lifted. »
