Regressive autism

[Major indication autism is mostly vaccine caused.]

I would also be particularly interested to learn of any documented cases of completely unvaccinated children who have later dramatically and inexplicably regressed into autism after a normal infancy. To date, no such case has ever been identified to me.

"They claim that autism naturally occurs at about 18 months, when the MMR is routinely given, so the association is merely coincidental and not causal.  But the onset of autism at 18 months is a recent  development.  Autism starting at 18 months rose very sharply in the mid-1980s, when the MMR vaccine came into wide use.  A coincidence?  Hardly!"--Dr Rimland

And this is regressive autism; it's not from birth. It happens sometimes within two days or a week. When the parents come in, the histories are so similar. We try not to suggest anything when we're taking a history. We just say, "What happened? What did you find? Did the child develop normally?" And the mother will say, "Yes, until..." and we know what she is going to say next: "...until some vaccine was given around 15 to 18 months." Doctors used to give the MMR on the same day as the DTP and the Hib, and that was usually the time the regression started. They've now shifted the schedule--the MMR is being given at 12 months.
