Whether it's one in 100,000 or one in 1,000,000, NEITHER of those are significant enough to be an anti-vax moron. I REALLY WISH i could give my cousin 5 minutes alone with each of those people concurrently. I know he would SURE love it.

Our sample size of 3 indicates that people over 30 are the prime target for these side symptoms, and that it doesn't matter if you're literally in fighting shape. Not very useful but it's an anecdote.
