Bill Maher: Vaccination: A Conversation Worth Havinghttp://therealbillmaher.blogspot.com/2009/11/vaccination-conversation-worth-having.html
Personally, I go without the 'flu shots'. Every time I have ever got one, the shot made me sick, then the very last time ever was for the 'wrong' variant of flu that came out that year, so I caught it anyway, and I got horribly sick.
Maybe I catch it every year, maybe I write it off as a 'cold'. When I get sick, it's usually mild. When I got vaccinated for it, I get sick whether I would have caught it or not, and that one time, I got clobbered.
This is not to say that flu shots aren't good for other people. Possibly they even are good for me
. I'm not going to do it again, for the wholly emotional and selfish reason of not liking the experience.
Of course, some statistics are misleading. It's true that only 11% of people who get tetanus DIE, 100% go through horrifically painful symptoms, including involuntary muscle contractions (aka 'charlie-horses') sometimes strong enough to break their bones. So I'd wager 89% wish they'd died. So gimme the tetanus shot, even if my arm gets sore.
Generally speaking, I agree more with Penn & Teller... if we're going to quote celebrity opinions.
