A significant influenza outbreak has infected at least 159 military recruits at Lackland Air Force Base in Texas. The surge in cases comes just weeks after U.S. Secretary of Defense Pete Hegseth terminated compulsory flu vaccinations for service members.

Hegseth announced the policy change in late April to restore medical autonomy and religious freedom. He characterized universal mandates as overly broad, stating that personal convictions regarding medical treatment are non-negotiable. Under the new directive, services had fifteen days to request exemptions if operational necessities required continued vaccination protocols.

The outbreak at Joint Base San Antonio highlights vulnerabilities in communal training environments where thousands of personnel share dormitories and dining facilities. While the death of trainee Keon McDaniel on June 16 remains under investigation, the cluster of illnesses prompted immediate administrative action.

The Pentagon has since granted an Exception to Policy allowing Lackland to reinstate mitigation measures. Medical teams from the 37th Training Wing and 59th Medical Wing are currently isolating symptomatic recruits and administering antiviral medications. This incident occurs against a backdrop of shifting federal health guidance, as the administration moves to make vaccine recommendations voluntary rather than mandatory across civilian and military sectors.
