I never used to get the flu shot, and I've never had the flu - just very occasional horrific colds. Now I have a germ factory though (ie. a child), the whole family gets flu shots. I wouldn't be too bothered if it was just me who got it, but given that the real flu (I hear so many people say they have the flu when it's just a cold) is supposed to really knock you around, I wouldn't want to risk being sick while looking after a child, or her getting sick.
