Refuted by comparative studies. Cheapest thing to do really but health authorities wont fund them. Theres a few docs out there doing it now and its stark. Unvaxxed kids very rarely autistic and also autoimmune diseases pretty much non existent. Everyone should be demanding a proper retroactive comparative study with multiple age cohorts and just put this discussion to bed finally with some good science. Going to need massive transparency effort cause this scam dwarfs smoking and stuff in terms of coverup and misinformation
