I also think there is a misconception as to what the 'flu' really is - it is not a stomach virus, it is not when you have cold like symptoms...a real flu, which the shot prevents, is a debilitating illness that keeps you in bed for days and days, and which (as when I had it) can actually land you in the hospital, which is why it is important for the elderly, for children and for pregnant women to get the shot. I think a lot of people (and I am not saying the prior two posters, just people in general) say they have the flu and really what they have is a horrible cold or stomach virus, but not the true flu.
