LMAO!!!Here's the deal. Back when autism rates were around 1 in 100,000 (prior to the proliferation of both childhood vaccinations and the widespread use of acetaminophen, COINCIDENTALLY!) kids never got fevers.
No.
Autism rates have not changed. ASD diagnosis criteria HAVE changed.
In fact, it is fairly likely that vaccines which protect against those viral infections linked to ASD actually provide a protective effect in limiting the severity of the infections.
