A flu shot gives yuo a mild case of teh flu (I believe).

I think it is based on the protiens that your body can recognise as being ones that would be on the surface of the virus itself.

Your body reacts, builds antibodies to fight it, and you are now prepared if you get hit with something that "looks" the same.

The reason it does not give you a full case of the flu is because it is only the "shell" or thethingers on the outside of the virus that your antibodies would attach to. It does not invade your cells and replicate, so once your body deals with it, it does not have to keep fighting it.

Unfortunately, some people react to it more than others, getting a mild case of the flu as their body fights off the dummy-virus.


BTW, most of the symptoms for colds and flus come from your body fighting it, not from the bug itself...
