Polio spreading thanks to anti-vaccination crowd
Not in the article, but my recollection is that these are not the normal "anti-vaccination due to autism" crowd, but the "anti-vaccination due to secret evil Western sterilization plans" crowd.
So there's three things going on here.
1) Thinking that the kids would have autism due to vaccinations.
2) Thinking that the kids would be sterilized due to vaccinations.
3) In Africa, guaranteeing the kids would be crippled or killed due to no vaccinations.
