I have read many post flu season news stories over the years that substantiate this point. Frequently, the article notes how the season's flu vaccination was not particularly helpful because the experts guessed wrong about the season's particular strain.
Personally, I don't waste my time with flu shots -- even though I could receive them free.
I have only had the Flu one time and that was when I was cajoled into taking a flu shot.
Of course in the Obama-Nation Swine Flu vaccination will be MANDITORY to avoid being sent to a Quarantine camp in Sunset, Montana.
