The best lead for me is an expert who used to testify for the govt in the Vaccine courts and even he refused to say that vaccines dont cause autism as a blanket statement. So they cancelled his testimony during a certain case and used his previous statement in another case fraudulently as if it applied to all cases.

He then became a whistleblower. And eventually it was established that kids with a specific mitochondrial condition are more prone to get autism when vaccinated.

Sorry, dont remember names but you should be able to search based on these.
