Except for H1N1, I don't think I've ever gotten a flu shot. I have no problems with vaccinations (heck, I'm vaccinated against chicken pox) or needles. I just don't like that the flu shot is a yearly thing, and not guaranteed at that (they try to predict the major strain they'll be up against).
If they come up with a one-time (maybe some boosters after a decade), one-size fits all, I'll take that. And if not, I'll get the flu shot when I'm old and vulnerable.
