This is part rant part genuine curiosity. I was recently surprised to find out that there are still people who think vaccines - including the new swine flu one - cause autism, despite huge scientific evidence disproving it. Urr, why? There are even people capaigning to have vaccines banned because of it, and I can get you linkage on that if you don't believe me. I seriously think some people must just be stupid. Or is there something else here I'm missing?
