| A doctor friend of which I have referred earlier indicated that in medical school, this was absolutely drilled into every student. To give a patient a drug without consent, even if it may be life-saving in nature, is considered to be “inflicting harm” and shall never be done.

I suppose we could debate if a vaccine is a "drug", but the overall population is not protected if too many patients refuse to be vaccinated. Certainly, those who will almost certainly have a significant adverse reaction to the vaccine should not receive it, but these cases will be sufficiently sparse for a well researched vaccine. We could debate about the COVID vaccines being "well researched" because they were developed on a faster track compared to the legacy vaccines.

Once we have a proven effective vaccine, is failure to administer it to the masses "inflicting harm"?
