My condemnation extends to nurses; no one is beyond criticism. Infact, a surprising number of nurses have insane ideas - more than you'd think. To wit, at my local hospital, a doctor found an abrasion on a patient's back which was later attributed to a "healing crystal" supplied - and installed - a few days before, by an attending nurse.

These people were putting their neck out almost a full year before the first shot was administeres. Chances are, many of them already acquired immunity via this route.
