Dozens of studies have failed to find evidence of a link. The decision to re-examine the question comes as a measles outbreak, driven by low vaccination rates, widens in Texas.
If they end up citing the famous Lancet paper, then you know they didn’t even try to make up new bullshit.
For anyone unaware, Lancet published a paper in 1998 that claimed there were links between the MMR vaccine and environmental triggers that lead to loss of acquired skills including language. The study being conducted turned out to be fraudulent, with parents of many of the children involved in lawsuits against the vaccine manufacturers, as well as unethical treatment of children. 12 years later in 2010, Lancet retracted the paper. This paper is a very well known source anti-vaccination proponents have frequently cited. https://pmc.ncbi.nlm.nih.gov/articles/PMC2831678/
In pursuing the study, the C.D.C. is defying the wishes of the chairman of the Senate Health Committee, Senator Bill Cassidy, who said this week that further research into any supposed link between vaccines and autism would be a waste of money and a distraction from research that might shed light on the “true reason” for a rise in autism rates.
If you want a real summary. In order for anything to cause autism it would need to permanently change the way your brain works and the two systems(vaccines and mutations) are separate. Vaccines introduce the equivalence of an antigen for you to make antibodies which is not genetic manipulation just hijacking/abusing signalling pathways.
A distant family member wasn't vaccinated (can't remember why his parents chose not to). But when he was around 20, he got tested and was diagnosed with autism. I remember him posting about it in his socials and was like, "well, I'm gonna go get vaccinated now!"
