Pentagon Reverses “Medical Autonomy” Policy; Reinstates Mandatory Flu Vaccines

The Department of Defense has reversed course after Secretary of Defense Pete Hegseth rescinded the flu shot mandate in April. The Hegseth Memorandum gave branches an opportunity to submit permissions for exceptions to keep the vaccine mandate for certain populations within the military. That has been granted now for the Army, Navy, Marine Corps, and Air Force to require all recruits in basic training boot camps to receive the influenza injection.

Secretary Hegseth cited medical autonomy, religious freedom, and concerns about broad mandates when he signed the directive in April. The mandates do not apply universally to all active-duty or reserve personnel, but target high-density training environments.

The latest reversal reflects another contradiction between the stated policies of the Trump administration and recent actions regarding vaccine mandates. In May, President Trump signed an executive order calling for a realignment of the childhood vaccination schedule to align with best practices from peer-developed nations. Within that order, President Trump states that his administration is committed to protecting religious liberty.

Informed Consent Action Network (ICAN) Attorney Aaron Siri revealed in May that the Trump administration issued a Supreme Court brief arguing that employers do not have to allow religious vaccination exemptions. Siri explained that the administration shamefully played “word games” and relied on “semantic nonsense” to argue the Supreme Court should not review the Second Circuit’s holding that a policy providing for medical but not religious exemptions is legal.

“Having dealt with scores of religious employees in New York that lost their jobs under this policy, the Trump administration’s position is a sharp betrayal,” Siri wrote. “The DOJ should have simply argued the obvious – that Section 2.61 foreclosed any religious exemption and hence should not stand under federal law. Period. That would have taken one or two pages. Instead, it spends over 20 pages creating a word salad of nonsense to justify New York’s and the DOJ’s unjustifiable position.”

Now the military has reversed course on vaccine mandates to allow for religious freedom and medical autonomy. There is currently a flu outbreak at Joint Base San Antonio-Lackland in Texas, with nearly 300 Air Force basic military trainees having tested positive for influenza since early June. Approximately 40% of trainees at the base opted for the vaccine during the voluntary period. Reports indicate there have been four hospitalizations connected to the camp, but it is unclear if they are connected to the influenza outbreak.

One basic military trainee at the Texas base died on June 16 after experiencing a medical emergency on June 12, but the cause of death has not been revealed, and it has not been connected to the influenza outbreak. Many media reports mention the death alongside the influenza outbreak and vaccine mandate news, but there is zero indication that he tested positive for the flu.

The exception approval letter states that the purpose of the influenza mandate is to “Maximize operational readiness, lethality, and force generation; safeguard immunocompromised or other at-risk populations; and provide stability of the home front allowing service members to remain focused on the mission.”

Based on CDC data, the most recent influenza vaccine has a 36% effectiveness rate. In her 2025 paper, Dr. Irene Mavrakakis questions the effectiveness of annual influenza vaccination. She said that even if it reduces the number of confirmed influenza cases, it may increase susceptibility to other respiratory viruses. Mavrakakis cited a DoD study that found a 36% higher rate of coronavirus infection among vaccinated personnel during the 2017-2018 season. She also cited multiple epidemiological studies inferring no clear mortality benefit from increased vaccination coverage.

Dr. Mavrakakis calls for the suspension of respiratory virus vaccination, including influenza and COVID-19, until further investigation and therapy are developed for potential cytokine storms that may follow vaccination.

CDC data shows that 71% of flu-related deaths are for individuals 65 and older, and 92% of all flu-related deaths are for individuals 50 and older. A study analyzing all-cause mortality following influenza hospitalizations found that 89.3% of all influenza deaths from individuals under 65 were individuals who had at least one underlying condition. The risk of severe outcomes for young adults who are members of the armed forces in basic training is rare.

Furthermore, the underlying conditions that are most commonly associated with poor outcomes following influenza infection and/or hospitalization are conditions that would disqualify somebody from enrolling in the military. These include asthma, obesity, diabetes, and hypertension.

The Vaccine Adverse Effect Reporting System (VAERS) collects passive surveillance reports of side effects from vaccination. From 2020 through 2025, there were 363 deaths, 399 Guillain-Barré syndrome reports, 420 seizures, and over 2,000 serious adverse event reports associated with influenza vaccines. These reports represent over 3% of the 55,476 total reports during this time period.

VAERS data do not prove causality, so some of these reported adverse events could be incidental and not caused by vaccination. A 2010 Harvard Pilgrim study concluded that fewer than 1% of all vaccine adverse events are reported.
