The Pentagon will no longer require troops to get annual flu vaccines, Defense Secretary Pete Hegseth said on Tuesday, calling the policy an “absurd, overreaching” mandate.

The vaccine will remain available to service members who want it, he said. “But we will not force you, because your body, your faith and your convictions are not negotiable,” Mr. Hegseth added.

Members of the Trump administration have been critical of vaccinations. While he has changed his tone in recent weeks, Health Secretary Robert F. Kennedy Jr. has a history of loudly questioning the safety and effectiveness of many standard vaccines.

Last year, the administration offered to reinstate troops who had been discharged for not taking the Covid-19 vaccine. Roughly 8,700 active duty and reserve troops voluntarily or involuntarily left the military after refusing to get vaccinated before the mandate was rescinded in 2023. As of last summer, 13 had been reinstated.

In March, Mr. Hegseth extended the deadline to apply for reinstatement. The new deadline is April 1, 2027.

U.S. military personnel are still required to get vaccinations for diseases including measles, mumps and polio. Others, such as the anthrax vaccine, may be required depending on risk and military occupation.

The flu vaccine requirement was put in place because medical professionals said it would reduce illness and improve the overall readiness of the force.

Mr. Hegseth was dismissive of that perspective in a video posted on Tuesday. He said the new policy would pose “no threat” to the military’s preparedness.
