Back to matters purely COVID...
For those wondering about the protection of prior infection versus vaccination, here's the answer. And one of many reasons why prior infection won't be considered a substitute for full vaccination:
This report describes mRNA COVID-19 vaccine recipients as having greater immunity from COVID-19 infection than previously infected, unvaccinated persons.

In short, vaccination provides 5x the protection of prior infection. We've kind of suspected this would be the case for awhile, because the antibody response to prior infection is far more variable than from vaccination. Here's the data that shows the results.
Like all things, though, we'll learn more as time goes on. It is possible that the protection from vaccination eventually fades below prior infection (a possibility mentioned by the study's authors), but at least as long as we've had the vaccines, they're offering more protection for now.
