I am an inorganic chemist by training, have an autistic daughter - and agree aluminum in vaccines is a great candidate for autism's root cause.
It might not be the only root cause - here is a great article about the heat generated from ultrasound medical treatments...
"Just as concerning, as far back as 1982, the World Health Organization (WHO)’s study, “Effects of Ultrasound on Biological Systems,” concluded that “neurological, behavioral, developmental, immunological, hematological changes and reduced fetal weight can result from exposure to ultrasound.” Two years later, the National Institutes of Health (NIH) reported that when birth defects occurred, the acoustic output of sonograms was usually high enough to cause considerable heat."
