Dozens of service members at Lackland Air Force Base in Texas have contracted the flu following the rescinding of the military’s long-standing vaccine mandate. The 37th Training Wing, which manages basic military training, is currently coordinating with the 59th Medical Wing to isolate and treat symptomatic recruits using antivirals like Tamiflu, according to an Air Force spokesperson.
Current Outbreak and Mitigation Efforts
The Air Force has implemented localized mitigation measures to curb the spread of the virus among trainees. While the service is monitoring those who may have been exposed, officials confirmed that only approximately 40% of trainees have opted to receive the flu vaccine since Defense Secretary Pete Hegseth removed the mandate in April. The current outbreak remains contained within the training environment at the Texas base.
Policy Changes and Operational Readiness
In April, Defense Secretary Pete Hegseth issued a memo ending the decades-long mandate, characterizing it as an “absurd, overreaching” requirement. Pentagon spokesman Sean Parnell stated on Thursday that the Department of Defense has since allowed the Army, Navy, Air Force, and other agencies to grant exceptions to policy (ETPs) if specific needs arise to make the vaccine mandatory. These decisions are reportedly guided by risk assessments intended to maintain “operational readiness, lethality, and force generation.”
Ongoing Investigations
The influenza outbreak coincides with an active investigation into the death of Keon McDaniel, a trainee in his sixth week of basic military training. McDaniel experienced a medical emergency on June 12 and was transported to Brooke Army Medical Center, where he died on June 16. The Air Force has not linked the medical emergency to the current influenza outbreak, and the investigation into the cause of death is ongoing.

What Happens Next
As the 37th Training Wing continues to manage the localized outbreak, medical teams are likely to maintain strict isolation protocols for symptomatic recruits to prevent further spread. If infection rates do not stabilize, the Under Secretary of Defense for Personnel and Readiness may face pressure to revisit the use of exceptions to policy for mandatory vaccinations within training environments to ensure force generation remains uninterrupted.
