Every study they have done shows no link between links and autism. They've taken out the thimerosal out of the vaccine, but studies in Great Britain where they never had thimerosal showed the same rate of autism. My sister has a son with autism, my son has mild Tourette's Syndrome, my daughter has ADHD, and we know that these things run in families together showing a genetic link. My dad, his mother, and her brothers and sisters had varying degrees of impairment from schizophrenia to just being uncomfortable in social situations because they weren't adept at reading social cues. All of these have to do with brain chemistry that isn't normal. Autism is a social impairment. My husband's son also has ADHD and mild autism. We're convinced there's a genetic link here. My sister's son showed some of the early signs of social impairment before having the mmr vaccine. If your child isn't pointing at objects by one year old its often an indication of autism or something on the autistic spectrum like Aspberger's. I believe the scientific evidence that vaccines don't cause autism.
