A flu shot is a no brainer for me. Do you guys quoting "60% ineffective" realize that not getting one is 100% ineffective?
I've never had a flu shot, and even with my "100% ineffective" status, that has somehow carried me for many years without getting the flu. I must be literally inhuman. I take no pills, get no shots, rarely visit a doctor, and yet, somehow, mind-mindbogglingly, I haven't died; not even once.
