Many of us in the civilian world can probably sympathize with two Dyess airmen who refused Pentagon orders to take an anthrax vaccine shot.
Anthrax sounds scary.
Like those two airmen, we might balk at being forced to take an anthrax shot. It's called following orders. If you can't, don't sign up. Doubts about the vaccine's safety and necessity, however, deserve a more elaborate response. Concern over safety is entirely reasonable.
