No, more like human history really.
You should probably go find some old people. Ask them about polio.
If they're old enough they will also tell me how there used to be no autists like you back in the old days before mass vaxx. Now that people are more vaxxed than ever it's commonplace and you can't go one week without meeting someone on the spectrum or hearing about it. I wonder why?
Autism existed. Facinsting read: the term was coined in 1911 (over 100 years after the first vaccine) to mean an excess of infentile fantasy in children. But this was challenged and rewritten in 1972 to mean a deficiency of fantasy.
1918 had the military made influeza vaccine to combat the spanish flu. It was inconclusive.
1937 had the yellow fever vaccine, which worked. Got the man a nobel prize.
1939 had the whooping cough vaccine which apparently wasn't 100% effective but went from 15.1 children/100 children to 2.3/100 children infection rate. Not bad.
1954 had the polio vaccine.
1960 had a second type of polio vaccine.
So yeah, vaccines have been around longer than the definition of Autism. And this wasn't because Autism didn't exist but rather it wasn't diagnosed properly.
Probably just called em Retard, slow, touched, posessed by satan, etc...
Well, considering that autism and all those terms are synonymous with brain damage - yes, I believe brain-damaged people existed before maxx vaccination. Duh.
But there's A LOT more since the mass vaxx, and steadily on the rise year after year.
Well.. no. Autism isn't brain damage. There's certainly something not wired properly, but its not actual damage. Damage implies it was fine beforehand.
As for why the rise:
Increase diagnosises, better access to such care, wider education on what autism is, and a rising population. Y'all always forget the population rise.
If 1% of people are autistic, more people will be diagnosed every year simply because the total population keeps growing. Simple math.
But its mostly better diagnostics. Plus some people are high functioning so they wouldn't have been diagnosed 20 years ago but now they would.
In any case, your entire belief on that comes from one debunked study that was never repeated. Much like believing in bigfoot because someone took a blurry picture of a tall, hairy humanoid. Probably.
