Really the paper is another effort to tie autism to getting childhood vaccinations
Some years ago I ran a call on a early to mid twenties non-verbal autistic patient living at home with mom and dad.
Dad came up to us and stated that patient had been a totally age appropriate kid about 10 years old when they were taken to a doctors office for childhood vaccines. The child reacted right there in the office and was transported to the ER and had been non-verbal autistic since that moment.
What he said was not really relevant to the call or treatment and I have always felt was a warning to us of potential consequences.
