From what I understand, his original paper was along the lines of having measles, mumps and rubella vaccines all in one injection was too much for the body to handle. This then caused a knock on effect which would cause issues in a child’s gut bacteria, and factored into a theory Wakefield and some other “doctors” were working on at the time which was that gut bacteria were a driver for autism.
I know. It’s crazy already.
But the craziest thing is that the paper doesn’t even advocate for vaccines to not be delivered, only for them to be delivered separately, one for each disease. The original grift was going to be that Wakefield and his company were going to sell the separate vaccines and make money that way.
There’s absolutely no substance at all to the original paper. It doesn’t even say what people think it says. It’s like a semi-grift trying to parade itself as reasonable, but it ended up getting away from them all and turning into a movement they couldn’t control.
