“And how much of this can be blamed on those morons who claimed that vaccines will cause autism?”
I would say all of it. I recall teaching in a private school a few years back. There were at least three families or more who refused to immunize their children in a school that did not require the kids to be vaccinated. I explained to them that childhood disease was the cause of a lot of deaths before immunizations, and their answer was always this nonsense about autism. Now, the inevitable is beginning to occur, and there will be serious consequences.
