  It's important to understand why reinfection might not be such a big problem. First, the virus can only spread broadly with an R0 above 1. Even if some portion of the population is susceptible to reinfection (vaccinated or natural immunity), so far there's been little evidence that it's widespread. In a fully vaccinated population, the R0 will only reach above 1 if the virus is able to break through vaccines wholesale. Second, the vaccines seem to be highly effective at preventing serious cases, hospitalizations, and deaths, even in reinfected individuals.

  No matter what you'd see greatly reduced spread. Ideally everyone would be vaccinated, but it would be unwise to ignore the substantial overlap between antivax people and antimask people. Everything pushing R beneath 1 is a good thing that should be counted.

  There has been 70 cases and 3 deaths of reinfection worldwide [0]. If this source is not false, reinfection is negligible, and I am yet unconvinced herd immunity will not materialise [0] https://bnonews.com/index.php/2020/08/covid-19-reinfection-tracker/ https://bnonews.com/index.php/2020/08/covid-19-reinfection-t...
