Something is causing Autism – I don’t know what. THAT is a risk for everyone. I labeled it “Regular Autism”. What would you like to call it?
Autism. Whether the subject had an MMR vaccine or not.
By labeling some as “regular autism” and some as “MMR autism” you are making an assumption that there’s either a difference in the condition in MMR vaccinated subjects and those without MMR, or that MMR is a cause. Neither are proven, and that’s precisely what the study is trying to determine.
