Also, I would still like to know which scientists who conducted the studies referenced in the "regardingcaroline" blog have been discredited.
I'm sure no-one thinks Doctors in the 1980s were incompetent, but the fact remains that Autism was less widely understood/thought about at that time, and so might not have been the first thing a Doctor would think of. It was only really recognised as a condition separate to mental retardation and other developmental disorders in the 1960s (http://en.wikipedia.org/wiki/Autism#History), so a lot of Doctors in the 1980s would have had their training before that, and or could have just not thought of it as a possibility.
Autism has been in the news a lot in the last decade (ironically - in my opinion at least - partially thanks to the controversy over it's possible link to vaccines) so is clearly more in the minds of Doctors today, and they are therefore more likely to consider it as a diagnosis.
As to the studies in the blog - I'd have to follow all the links to get to the authors, and I think there are better uses of my time. I did notice that it only included links to studies possibly linking autism/allergies to immune system disorders and/or vaccination status, while I'm aware of just as many showing no link (for example the one we discussed here: http://www.mothering.com/community/t/1353634/vaxxed-vs-unvaxxed-study/20). Funny they weren't included.... or maybe it's not. My point though is that it's hardly an unbiased literature review.
If you want that, try the Cochrane Review (not for profit reviews of the medical literature and produces "opinion" pieces on it). For example: A Cochrane Systematic review in 2004 (this one: http://www.ncbi.nlm.nih.gov/pubmed/14871632) found no difference in the rates of children with neurological problems between those who had had a DTP vaccine with or without an aluminium adjuvant.
