My dad was disabled from a childhood bout w/polio (feet were different sizes).

In my early 30s, I had to get a polio booster shot before I traveled overseas, among other shots.

I get the flu shot because they give it to us at work---convenient, free, etc. I decided not to get the H1N1, if they have any left for the rest of us (not pregnant, no little kids/babies in the house, etc.) I figure that by the time it's available, I'll likely have already been exposed to the virus.

This definitely is one of those personal choices, so everyone has to do what's right for them.
