Given that the flu is a virus & will only last ~6-10 days, unless you are in one of the higher risk groups I don't see what all the fuss over getting vaccinated for it is. I can understand getting one for something that it will protect me for multiple years or longer or has long term consequences (i.e. polio, mumps, etc.) but not one that changes from year to year. Given my track record, I'll risk getting it at most three times in my life.
