I have not had the flu shots in well over ten years and I am totally okay with that.
I was a guest at a relatives house this summer and fall, and one day she got a wild hair up her a** and she sent me emails from her work using (us.army.mil) mail servers demanding that I get both both flu shots. I got myself out of her house in less than 3 days.
I dont know if she ever got in trouble for that (she is a civilian paralegal in the legal department at a US Army Depot) but I believe that she should have.
