I haven't gotten a flu shot since the Wu Flu came out, because they started talking about putting them in the same shot after a bit.
I rarely got the flu shot before that, to be fair, because I understood medical quality control/effectiveness was often exaggerated and doubted the shot did anything for me for a long time.
I won't shit on TDAP or malaria or anthrax shots, those are proven and effective products, but flu shots are crap in terms of effectiveness, 60% at best, and 60% would get you a low D on any grade school or college test, why should I trust it from a medical group?
That's not even touching the Wu Flu vax itself, which is at best a placebo, at worst an effective human genophage, and we don't have the same number of kids the krogan do.
