I would not put 100% faith in that. It might be true or might not be that he was wrong. There have been doctors in both Australia and South Africa suffer medical wrath from their peers for bucking the trend on nutrition. Look up Dr Tim Noakes and Dr Gary Fetke. Noakes took it all the way to trial and eventually won, at a great cost of time and money.

Nearly anything that bucks conventional wisdom is first ridiculed and discredited. If there is big money involved (as in drug companies that produce vaccines) double that.

Not saying the vaccine thing is one way or the other. Just that "proof" is not always proof. Sometimes it is easier to discredit someone instead of proving them wrong. Caveat emptor. As far as his claim of causing gut inflammation, there have been cases of a fecal transplant improving autistic children symptoms. So there is a lot we still don't know about such things.

Edit: here is a good example of how conventional wisdom is kept going by the powers that be. This is not about autism or vaccines, but is another subject that is controversial and shows how sometimes what we have been taught for years and is still conventional wisdom within the medical community yet if a person actually follows the science and published evidence is false. It has been around for 50 years, has much science proving it is wrong for the last 20 years, yet still persists as conventional wisdom for the majority of people. Once something is ingrained, it can take years and years to convince people what they have been taught has been wrong. Sometimes a new generation has to come along to get the change implemented. Maybe we will learn things about vaccines that only a few pioneers were bold enough to buck the trend? Don't know. https://www.youtube.com/watch?v=Q2UnOryQiIY&t=1412s
