I lean mildly libertarian (flairs do not allow for a lot of nuance), but I happen to think that tamping down needless suffering from highly contagious diseases is a good thing. The R0 of Delta right now from my understanding is about 7-8, which is about on par with rubella, which all of us have been vaccinated against without so much as a whimper except from the extreme anti-vax crazies. To have a further comparison, the death rate of rubella is comparable to that of COVID in developed countries (about 0.05 percent). The side effects and death rate of having rubella are brutal, especially to children and newborns. We're at the other end of the scale on COVID - it's mostly deadly to the elderly, but can cause severe, long lasting effects in adults - there are Long COVID sufferers, of which I know at least one personally who is my age (mid 30s), who got COVID in April of 2020 and he's had chronic fatigue, shortness of breath, and mental fog with no abatement since. He was in great shape before, and now he can barely go up a flight of stairs without gasping for air.

Anyway, I don't favor a federal government vaccine mandate or a federal vaccine passport, but it's fairly good and settled law that the individual states are permitted to mandate vaccines since a 1905 Supreme Court decision - 10th amendment and all that. This hasn't been controversial for a hundred years, and there's no good evidence that should change now.

I'm sure I'd run afoul of some other folks who might lean or ascribe to being libertarian for being strongly pro-life or favoring strict border security as well. But I also favor getting rid of the death penalty and generally reducing penalties and changing policy on minor drug crimes - there's literally zero good evidence for marijuana being a schedule 1 drug, for instance. I have literally zero interest in trying it. But I don't think it ought to be a felony offense, either.

Hope that makes sense.
