Vaccine hater BS
In the 80's and 90's the vaccine haters were trying to sell us either sids
or CP as caused by vaccine use.
Given that their true causes eluded researchers at the tme it was easy to convince some of their followers. They could never explain why we had sids in the bible( solomon's baby division story) or egyptian tombs. They moved on to other issues to hate when this was idea was debunked.
