"he said that MMR caused autism - no evidence." No, he didn't. He said that he believed that for a subset of children there were increased risks from combined vaccines, and recommended that single vaccines be available to children from certain groups. There are people who are far more knowledgeable on this subject than I am and who can write more elequantly about it, but the general belief here was that for some children, there was a predisposition to autism, and that for those children there may be certain triggers which, if avoided, may prevent regression. There is a difference between that and saying that mmr "causes" autism. The only people who made the claims that mmr caused autism were the tabloid press.
"he said that MMR caused stomach problems - no evidence." again you are wrong. The study conducted found evidence of measles in the gut of children with autism - I have even less knowledge on the exact science of this but it is now a proven and recognized fact that there is corallation between autism and gut problems.
