We are barely out of the dark-ages of medicine and there are fundamental shifts in perspective every day. (Like the new link between viruses and everything from Alzheimer's to cancer.) Even "folksy"-seeming perspectives like the linking the gut to seemingly unrelated areas like the brain turn out to have been correct. And as for the "anti-vaxers", I had dismissed them out-of-hand until I spend time with several neurologists (both researchers and practitioners) that were staying at my hotel for a conference, and after a few drinks and stealthy nametag removal admitted they are in general not willing to administer most vaccines to themselves or their own children. (I can do into a few more details, but I do not wish to start a anti-vax flamewar...)
