Its kind of funny, but people who’ve been in the military are more naturally suspicious of shots. I remember getting those appointment cards to go get the next flu shot. Seems we were the test cases for new flu vaccines. It was an Article 15 for not getting them.
Its also a fact that the cocktail of shots they gave soldiers on their way to Iraq is what caused many of the MS cases they are seeing in Iraq war vets. One of them is in my family. So the suspicion has merit, Jim!

And for the record, its not just religious reasons people object to vaccinations. Jim Carrey and his ilk have awhole following of antivaxxers based on nothing but conspiracy theories.

And on edit, when I went to the PI while working for Verizon I had to go get a series of shots, but I can’tremember if it was mandatory or not.
