Rainman introduces autism ie brain damage

What if the movie Rainman was a predictive programming psychological operation to introduce the word autism into public consciousness and normalize it into widespread acceptance?

The movie came out in 1988, and the National Childhood Vaccine Injury Act was signed in 1986.

Do you think that is a coincidence? Or was it an intentional preparation for the tsunami of autism and other neurological disorders that they knew were coming because they were adding dozens and dozens of mercury/aluminum filled shots to the schedule that would cause brain damage?
