That's precisely the point - early "radiation therapy" or homeopathy didn't have any solid scientific base either then or today, it was all snake oil from the beginning.

At the same time vaccinations, even the early ones, had a very strong and visible positive health on both individual chances of survival and herd immunity.

It's a bit like equating modern antibiotics with Jerzy Zięba dried beetroot pills and saying "in general, we should distrust them all"...
