Flu Vaccine: Do it or not?

[freedomfromforum]

I understand exactly how immunizations work. I alluded to the fact that my immune system already has it's defenses built up by having learned how to ward off the virus over decades of structuring. The immune system responds like a bum on welfare. If you give it what it should work for, it learns to not work for itself, and awaits next years welfare check via 'flu shot'. My body has thus-far performed per its building-up, and I see no need to communicate to my immune system that I don't trust it by introducing it to an unnecessary battle.

ETA: As a human in a world filled with viruses, I am constantly being exposed to countless 'immunizations' via exposure. My immune system remains 'kick-started' at all times.
