Ok, here is a possible answer. Autism is likely caused by an autoimmune issue. Most people with autism have leaky gut syndrome, celiac or some other autoimmune issue. I would suspect that one has to have a preexisting susceptibility that "could" be triggered by a vaccine. Other immune altering triggers could also cause autism to express itself.

For myself, my autism symptoms DID begin after I had a very severe reaction to an MMR vaccination (have scars on my arm). That said, I would probably have been on the autism spectrum anyway ... once exposed to any severe viral infection. I've improved over the years but I've had setbacks after severe flu episodes and so forth. I also have several autoimmune issues.

As with with most medical problems, autism has a mix of causes, triggers and unique genetics of the individuals affected.

When I was very young, I was starting to become autistic, according to my Dad (R.I.P.), but I was ultimately brought out of it, thank goodness. But I always seem to have had some strangeness from time to time. Maybe I was sensitive to vaxxes as a kid, but more likely, something else might have been involved.
