The syringes are single use, mass produced disposable syringes. They are not individually serialized, nor do they come in a serialized bag. After use, they are tossed in a sharps receptacle.
On the other hand, after my shot a guy in a suit with dark sunglasses and a wire in his ear walked in and told the nurse “don’t worry about this one, we got his DNA when he was in the military”, so maybe my experience was different. /nutcase
This is what I am asking, do you know for sure? I hope my curiosity can be put to rest by someone who administers them and has hands on knowledge of the protocols...
Maybe different than the experience of the original poster, but I work it this way for all military folks.
By the way, that was just a hearing aid you saw in my ear, not a radio receiver.
LOL!
