I swear to GOD, if I hear anyone talk about vaccines and autism link being a thing I'll blow a gasket. There are people who claim vaccines are useless and that the rate of death and disease were already going down and would have naturally been gone in a decade without vaccines.  Yes, sure, that's why 3rd world countries still have diseases that have been pretty much taken off the map in countries that have vaccines. Maybe when there is a vaccine for AIDs and they see that African rates of AIDs drop to almost zero it might make an impression.
