All military branches began requiring recruits to get flu vaccines earlier this month, an exception to Pete Hegseth's decision to lift the military's vaccine mandate, a Pentagon official said.

A flu outbreak at a basic training facility for the Air Force in San Antonio, Texas, is growing to at least 222 cases and four hospitalizations.

As of June 19, around 222 flu cases were reported on Lackland Air Force Base in San Antonio, Texas

Hegseth had announced a vaccine rollback in April and described the mandate as an issue of "medical autonomy" and religious freedom.
