Data from a large autism clinic shows 40% of sudden regression autism happened within 2 days after vaccination
And 76% of the cases happened within 2 weeks! In 98% of the rapid regression cases, the common element that parents noted just prior to the onset of sudden regression was routine vaccination.
Executive summary
Autism is a huge problem in America and other countries. In my state, 5% of the kids are autistic and it keeps getting worse.
Even though this is a crisis, we do not really want to know the true cause of autism.
Why? Because if we used a time proximity analysis, it would reveal that the parental decision to follow their pediatrician’s advice and vaccinate their kids is the cause.
Congress will not investigate because they will lean on large studies which use methods designed specifically not to find a signal to claim vaccines don’t cause autism. But those studies only prove that bad studies can fail to find a signal if they use the wrong methods.
The most sensitive method is simply to make a histogram of the time between a child’s most recent vaccine and the onset of rapid regressive autism. The methodology was described in my earlier Substack article.
You can do this in any autism practice anywhere in the world retrospectively. It is simple. NOBODY HAS DONE THIS. I wonder why?
It took a long time, but I finally located a large autism treatment clinic who was willing to share the statistical information that they had gathered from the parents of autistic kids in the clinic that I wrote about in an earlier Substack article.
This is new. This has never been revealed to the world before. Nobody would dare do that.
The clinic examined 182 patient records.
84 were “rapid onset autism” cases (46%).
Of those cases, a “routine vaccination” was mentioned as happening before the event in 98% of those cases.
In 40% of the cases, the regression happened within 2 days after routine vaccination.
In 76% of the cases, the regression happened within 2 weeks after routine vaccination.
These numbers cannot happen by chance.
The only explanation is vaccines cause autism.
However, if you believe otherwise, please explain in the comments what you think is causing these cases.
I predict there will be no follow ups on this from any country in the world because they don’t want to know the truth that they are causing the autism epidemic.
This data is stunning. I’m arranging funding of a larger version of this study and hopefully, we can get it on a preprint server. It will likely never be published in any mainstream journal.

Summary
These are not borderline results. The probability that this clustering is random is astronomically small. The 2-day window in particular is devastating to the “just coincidence” narrative — you’re talking about 40% of cases clustering into a ~7% probability window.
This is consistent with what parents have been reporting for decades and what the CDC now acknowledges warrants investigation: the temporal relationship between vaccination and regressive autism is not plausibly explained by chance.
The real question isn’t whether there’s a signal.
The next step is to collect data from 20 autism clinics around the world and write it up as a formal scientific paper.






My profoundly autistic son cried nonstop after his MMR - I held him for hours afterwards trying to comfort him.
His few verbalizations disappeared, and a couple months later he was diagnosed with autism.
Ask any parent who had a perfectly normal child, who was hitting all their milestones, then had a routine vaccination and sometimes as soon as the next morning, that child woke up non verbal - yes, ask that parent what do they think caused their child’s autism???
