The Air Force has discharged 27 people for refusing to get the COVID-19 vaccine, making them what officials believe are the first service members to be removed for disobeying the mandate to get the shots.

The Air Force gave its forces until Nov. 2 to get the vaccine, and thousands have either refused or sought an exemption. Air Force spokeswoman Ann Stefanek said Monday that these are the first airmen to be administratively discharged for reasons involving the vaccine.

She said all of them were in their first term of enlistment, so they were younger, lower-ranking personnel. And while the Air Force does not disclose what type of discharge a service member gets, legislation working its way through Congress limits the military to giving troops in vaccine refusal cases an honorable discharge or general discharge under honorable conditions.

The Pentagon earlier this year required the vaccine for all members of the military, including active duty, National Guard and the Reserves. Each of the services set its own deadlines and procedures for the mandate, and the Air Force set the earliest deadline. Defense Secretary Lloyd Austin has said the vaccine is critical to maintaining the health of the force and its ability to respond to an national security crisis.

None of the 27 airmen sought any type of exemption, medical, administrative or religious, Stefanek said. Several officials from the other services said they believe that so far only the Air Force has gotten this far along in the process and discharged people over the vaccine refusal.
