I would agree.
Autism has been around before vaccines and the definition charges nearly daily to include all kinds of “stuff” not previously included.
Just because autism was around before vaccines, doesn’t mean that vaccines aren’t one of several environment triggers for autism (in people who are genetically predisposed to it).
Not that I’m a vaccine-autism believer (we selectively vaccinate and delay some vaccinations for several reasons).
There was another thread on this earlier today that dealt with several good explanations for the increase in autism (including better diagnostic skills and expanding definition). I’m just not going to rule out the link.
