The guy who spawned the whole vaccine's causes autism wasn't actually claiming _all_ vaccines cause autism. It was a commercial endeavor for people to buy his vaccine [1].

Granted, if you notice something is bad (say lead in gasoline) it's pretty worthwhile for you to profit from improving it. But the thing actually needs to be demonstrable bad.

There is a correlation about mothers taking acetaminophen leading to Autism. There is also a correlation about mothers drinking water and it leading to Autism.

Doesn't mean its the right connection. Effectively every first world mother in the past few decades has taken acetaminophen whilst pregnant, given its one of the only possible pain medications allowed, yet we don't see 99% Autism rates.
