We run into the same problem at my office. I work in a hospital. It is mandated that every employee get a flu vaccine every year. To me it's a no brainer. However, every year I hear the same bullshit: "I never get sick, so why do I need the vaccine"; "Last year I got the vaccine and then I got the flu right away"; "I just don't think it's fair that they can tell me what to put in my body"; etc, etc, etc. I used to try to reason with people. Now I just get pissed and remind them that the for cancer patients that they pass by in the hallway without even knowing it, or never pass by at all but leave their germs for on each door handle and hanging in the air, a flu isn't an inconvenience, it's a death sentence, so shame on them for being so goddam selfish. It usually works.
