I doubt that more scientific studies on the "link" between vaccines and autism will be fruitful, either in reducing the incidence of autism, or of convincing parents to have their children vaccinated with the present vaccines, a new protocol, or to stop advocating against scientific evidence because it is all tainted by corruption.
Science has no place in the autism-and-vaccines/immune/diet/whatever world that the advocates inhabit. I am a mother with a Canadian Grade 12 science diploma and these people's science illiteracy is either absent since elementary school, or abrogated for more glowing forms of knowing like "motherhood" or new age inspiration. Perhaps the sociological study of why this view of autism is so popular is the best way for science to be applied to this risk to human health.
