Flu vaccine mandate returns as military battles outbreak at Lackland

After a flu outbreak at Lackland Air Force Base sickened about 222 recruits (four hospitalizations; one death, cause unclear), the Army, Navy, and Air Force reinstated mandatory influenza vaccination for basic trainees, reversing Defense Secretary Hegseth’s earlier stance that shots were optional. The Pentagon says exemptions were reviewed to protect readiness; the Air Force plans to vaccinate all recruits at the base, and the Army may extend the policy to other groups. Only about 40% of new Air Force trainees at Lackland were vaccinated, highlighting ongoing vaccination debates in the military.
