If anyone's interested, here's a very simple pro-vax argument that relies on the real figures and not the lies.

The main fear that anti-vax people have, is brain injury caused by encephalitis. Encephalitis IS a possible vaccine side effect, at a rate of roughly 1 in 130000.

Encephalitis is also a possible side effect of measles, at a rate of around 1 in 600.

In other words, a child is 200x more likely to get "the scariest side effect" from measles than they are from the MMR.

People don't bother to explain that though, they're happier just saying "reeeeeee if your child gets measles their head will fall off, so you must hate them and be pro-death, get out of our schools reee"
