Not sure about this. I know some people who got out instead of getting the anthrax vaccine.
That said, I think I got like 16 vaccines my first week of bootcamp whether I needed them or not!
Lost my Shot records once... before they went digital. That was a toejamty ordeal. Got 3 of the Anthrax ones, didn't think it was a big deal as a Vet(erinarian) in the family told me they'd been getting it for decades. That one DID do some weird toejam to me for a couple days.
Balked at the idea of getting a shot to combat COVIDIOCY. Wore a mask 3 times, all of which were required to walk in the VA to get HBP meds, would have told them where to stick their Jab had I needed to.
