dunno bout vaccination but wether it influences or not autism rate, that is/may only a fraction of the reason
its due to americans junk food diet that its number 1 in autism. and 1 in 67? where u get that number
pretty sure its outdated, i read recently it was around 1 in 40 or something.
by 2030 there will be 1 out of 2 autistic retards in the united states.
its common sense, go read statictics of sugared drinks consumption from 1950 to 2015...
p.s. and there's also the chemtrail factor. poisoning the farms with hard metals (barium, aluminum, arsenic, lead, mercury)
but that is another subject not willing to debate with the retard consensus on this forum.
