Very likely that’s the one. I know someone who used to believe it had a significant link to Autism when injected to the mother during pregnancy.
They now acknowledge this is not the case, but have implied that they still suspect a link might exist to some medicine that military hospitals were administering to mothers around the year 2000.
I’ve no evidence for or against. But there is undeniably a link to military service of one or both parents. That’s the only definitive I have about ASD. That, and of course that anyone who self-diagnoses themselves with it is mentally unwell in a whole different way.
