I think that's fake news. Gundry is PRO vax. I just watched a youtube where he said there was nothing proven wrong in the vax. I had never heard of him before this thread, but watched his youtube and found he is OFF on some science (chemistry), and he's really more interested in selling supplements.

His big deal is getting bean eaters to wash out the Lectins and ferment them gently before eating them.

He's making a good business out of it.
