Well I'm the mother of a vaccine damaged autistic child and don't have the energy to look for something to blame- I tend to be too busy getting on with it. I'm interested in what happened to my son as I didn't/don't want the same thing to happen to ds2 and ds3 (being non-verbal at 6 is not fun- least of all for the child).
The theory (even Wakefield's) has moved on now. A lot of evidence points to MERCURY in vaccines (ie thimerosal) being the biggest culprit. Autistic children don't get rid of mercury very well, that much is known, mercury is a toxin, that is also known. Where does the MMR come in (as it doesn't contain mercury)? Well the same proteins that remove mercury from the body, are involved in response to viruses- so you get a double trigger. The children who regress after the MMR are different (whoops they're pointing, oh no now they're not, and oh they've just screamed for 3 days non stop- must have missed that behaviour before). Walsh who is the big mercury guy in the States says that MMR could be a problem in combination with mercury- he thinks the 2 factors may go together.
BTW only 7% of cases of autism are believed to be triggered by the MMR- too small to pick up via epidemiology.
Of COURSE genetics is involved. But heredity is more than genetics.- the environment plays a part as well. If you are born with a difficulty in getting rid of mercury from the body and you don't meet any you're fine, if you do come into contact with it then you are stuffed.
Probably zebra- I didn't follow OJ Simpson's case- my point was you could say that about any PCR study- which is why these studies need to be conducted very carefully- an OJ SImpson contamination woujld be more likely though- lots of humans around- where's all the mealses virus contamination coming from- it's not just floating around at high concentrations in the air. If they're keeping measles virus in the same lab then I would hope they used proceudres to prevent cross- contamination.
I really find it offensive when people say that we're just looking for something to blame, like we're fragile eggshell like personalities, who must be sitting at home wringing our hands and sobbing into our handkerchiefs whilst raging agains the world at the unfairness of having our little autistics. Bah! Bollards!
