It’s Dr. Paul Thomas - he owned and operated a family medicine clinic for decades.

He had a large subset of child patients at his clinical from rural Oregon who were unvaccinated from birth and used his clinic for all medical visits growing up.

After some time he got a hunch that unvaxxed kids were healthier. So he ran a comparison from his data and found the exact same thing as the Henry Ford study: unvaccinated kids had substantially less chronic disease than their vaxxed counterparts. 2x-6x the chronic health conditions in vaxxed vs unvaxxed baseline and not one category was found where vaxxed kids were better off.
