Hot take (at least among my Libertarian and Republican friends):
The idea of medical professionals going door to door and asking people if they'd like a vaccine doesn't sound all that bad to me, at least from what I've read so far.*
My only objection to covid regulations was that they were mandatory. I object to curfews, arbitrarily shutting down businesses, and, of course, mandatory vaccines because I see such invasive legal practices as a greater threat than covid itself.
That said, I do believe people should voluntarily do their civic duty and take certain responsibilities upon themselves. Additionally, I'm vaccinated (not saying that as a virtue-signalling thing but as a statement of fact) and I don't think getting a vaccine, even a not-fully-tested one, is the tumultuous risk naysayers make it out to be. It's honestly no big deal and we shouldn't attach so much political meaning to it. Furthermore, and, perhaps, most controversially, I don't object to the government taking a proactive approach to curbing the pandemic's spread. In fact, it should do everything short of severely curtailing individual rights to fight the virus.
With that in mind, I just don't see medical professionals going door to door offering vaccines as a big deal and certainly not some kind of a Nazi dog-whistle.
As long as they're not forcing the vaccine on people or forcing people to relay whether or not they already had the vaccine, I don't see it as problematic at all and, in fact, think it might be exactly the sort of non-authoritarian government activism we should welcome, particularly if it's done in coordination with local medical professionals at minimal taxpayer expense.
I don't even mind if the door-knockers ask if the household has been vaccinated and take note of the answer.
Mormons and Seventh Day Adventists do this sort of thing all the time. Are you afraid of them? Do they force anything on you? No. You can invite them in for tea and theological discussion if you'd like, or flip them the bird and tell them to go die because this is America. Of course, you could also ignore them entirely.
Thus, as long as the vaccine door-knockers operate in much the same way as Mormon or Seventh Day Adventists, I'm more or less inclined to say that I'm all for it. Census workers also come to mind. It's just not scary to me.
It's a proactive government approach that still leaves the power in the hands of the citizen. And that's exactly the kind of government I don't hate (again, assuming taxpayer expense is minimal. I won't support the creation of another bloated federal alphabet bureaucracy).
*As always, I reserve the right to change my mind.
