Secret's out! Apparently if you vaccinate your kids, you're just asking for them to "catch autism." However, it appears Amish children are in the clear. If by "clear" you include genetic diseases and Amish in the City.
I am not a parent, nor a medical professional, so I'm going to stop right here about the evils of vaccinations. You know, Satan in a needle, all that, etc. Yep. Righhhttttt...... heeeeerrre.
