More than 160 service members at Joint Base San Antonio–Lackland in Texas have contracted influenza in recent weeks, according to The Hill, following Defense Secretary Pete Hegseth’s decision earlier this year to end the Pentagon’s mandatory flu vaccination policy.
- Cases reported: More than 160 troops at Lackland have reportedly been diagnosed with influenza in recent weeks, The Hill reported.
- Location: Joint Base San Antonio–Lackland (Lackland Air Force Base), Texas.
- Policy change: Defense Secretary Pete Hegseth ended mandatory flu vaccinations earlier this year, according to The Hill.
- Operational concern: The outbreak is raising questions about force health protection and medical readiness as the Air Force responds, The Hill reported.
- Service impact: The affected population is described as service members; The Hill did not specify how many were trainees versus permanent-party personnel in its report.
Brief context
Seasonal influenza can spread quickly in close-contact settings common to military environments—particularly training pipelines, dormitory-style housing, and high-throughput medical and administrative processing centers. Lackland is a major Air Force training hub, which can increase exposure risk when respiratory illness circulates.
The reported outbreak arrives after the Pentagon’s shift away from a universal flu shot requirement, a change that may alter unit-level prevention strategies and increase reliance on other measures such as screening, isolation protocols, and targeted vaccination campaigns. The Hill reported that the Air Force is responding to the situation, but details on specific mitigation steps, hospitalization rates, or duty restrictions were not provided in the report.
What it means for you
- If you’re stationed at or traveling through JBSA–Lackland: Expect possible health-protection measures such as increased symptom screening, guidance to stay home when ill, or limits on group activities if commanders and medical leaders tighten controls.
- If you’re in a training environment: Respiratory outbreaks can affect class schedules, appointments, and in-processing timelines if isolation or cohorting is implemented.
- If you rely on TRICARE: Influenza testing and treatment are generally covered subject to plan rules; follow local medical guidance and seek care promptly if symptoms worsen.
