Firstly, I was in ASHB (Aust Society for Human Biol) for over 15 years (ex 1 was founding member). I also attended virtually all their annual conferences with her (would still be doing so if the other ASHB members could not cope with our continuing friendship after the split). The Conferences have virtually all the HB research papers for the Asia Pacific region, although often the spread was worldwide.
The reason I went to the original research on vaccines is because my 21 month old son had a 400 word vocab and was normal in every metric until one day at 11am he had his "18 month ish" vaccine. From 11am to 2pm that day his lights went out. Three months later: diagnosed as severely autistic. Despite reporting it to the medical establishment in Colorado at the time, literally no one wanted to know. Neither ex 2 or myself have had even the smallest contact about it, and the group she is involved in over there has dozens of parents with similar stories.
AFAIAC, something to do with that injection caused it, whether the injection, the carrier or some contamination. FWIW, I doubt it was the vaccine itself. How much research did I find in the HB / med areas that actually even attempted to make that link? You probably know the answer to that: Zip.
As a result I take exception to vaccine / loony comment until someone (probably another private citizen) bites the bullet and has a good hard look at the cases and backtracks to causal links. The chances of big pharma doing that one in the US would be exactly zero in my view. FWIW, I could not even find a decent study which made the faintest attempt to run any type of autism / vaccine / control linkage study, even though a lot of the former eastern block countries would provide a good large sample.
If you know of some research I don't, I would love to see it. Until that is available, I express serious concern about the recent trend we in Oz are importing from the US of forcing vaccinations on parents. In my case, hell would have to freeze over for three weeks first...
