Disabled from a flu shot

[otters]

Its a ridiculously weakened version of the flu, and if I remember right, most of the virus is actually dead, but that is just how vaccines work. They inject a weak version of whatever you're being vaccinated from into your body, hopefully your immune system goes 'woh, thats some bad shit', attacks it, and registers it in its magic 'this shit is bad' database so the next time the virus gets in your body, your immune system kicks its ass before it has a chance to give you the cough/sinus/stomach/whatever crap.

Dude, alco, nobody can explain shit like you.
