A recent policy change by the Pentagon has had significant consequences for military personnel at Lackland. In April, the decision was made to make flu shots voluntary for all personnel.

Further details about the impact of this policy change can be found through the San Antonio Report, which initially posted information on this issue on June 30, 2026.
