s no way to tell for sure, but more and more proof is coming out that autism is NOT linked to vaccines,
and because
depo provera is an active hormone shot
and not a vaccine, I highly doubt that it is the cause. Are your other children girls by any chance? Very often a family that has an autistic child only has 1 (almost always a boy), and the rest of the children are "normal". They are thinking more and more that it's a genetic mutation.
