Basically, they don't know what causes autism, but there is a strong genetic link behind it. For example, if one identical twin is autistic the chances of the other twin being autistic is like 90%.

Anyway, autistic symptoms do not start to appear in children until they are about 18 months old, just about the same time as they get the MMR booster.

And, as epidemologists say, "Correlation does not equal causation".
