Never had the flu shot, only had the flu once in my life and that was thanks to a very sick clients coming in when she should have stayed home...and coughing all over the place... Even then I only got a mild case...24 hour eddition.
My neibour on the other hand has gotten the flu shot every year since ive known her...(11 years) and always spends 2 weeks down with the flu... This year she decided not to get the flu shot and hasent gotten the flu for the first time....
The way I look at it, id rather work on being healthy and boosting my immune system to naturaly fight off nastys. In the event that I were to get the flu,mmy immune sytem is better able to handle things on its own and the flu is a known component that i know what to exspect and what can be done to minamize down time.
The flu shot is a wild card. Nobody really knows what the long time risk are. There are things in it that I know I do not want in my body. To many variables, to many unknowns to risk pumping it into my body on the assumption that it "might" help me avoid a couple out of hundreds of flu strains. I dont think "avoid poisens" should be limited to my food.
Avoid Sick people that insist on coughing all over you, is also good policy
