...this sort of thing is not done without serious consideration, and in the case of COVID-19 with over 750,000 lives already lost, the use of mandates has very credible support...moreover, beyond the death toll, we have seen numerous instances of entire state HC systems being overwhelmed...IMO this is a threat to the "Common Good" and warrants the use of mandates if we have another surge.
As for "Healthy People"...we've seen reports of 40 yr olds in tip-top shape dying of COVID...not a lot, but emblematic of the inability to know who is and who isn't really "Healthy"...plus the Healthy ones can still become spreaders to the vulnerable ones...in short, when dealing with communicable diseases...EVERYONE needs to get vaccinated.
This is a Public Heath issue...not a political one...btw, I'll bet Madison's wife, Dolly, would have supported mandatory vaccinations for Yellow Fever, if they were available.
