Based on the number of deaths, a very large percentage of people have already had COVID.

Given that there is a non-0% chance of death or harm from taking the vaccine, why should they then get vaccinated? They are already less of a risk to themselves and others than someone who has been vaccinated.

> The researchers also found that people who had SARS-CoV-2 previously and then received one dose of the Pfizer-BioNTech messenger RNA (mRNA) vaccine were more highly protected against reinfection than those who once had the virus and were still unvaccinated.

Which is still a good argument against double-vaccinating them, at least when vaccines were hard to come by (which is still the case in most of the world).

At least that’s how France does it, and that strategy might come in handy again as they plan to give boosters with influenza vaccines to everyone over 65.

Single dose has been the recommendation for a while in the US.

Only for JNJ vaccine which has been 1-shot for everyone.

> why should they then get vaccinated?

I haven't done the sums but I suspect the risk of harm from the vaccine is less than the benefits the vaccine gives (especially when you factor in the duration of protecection depending when you had Covid vs when you had the vaccine).

I know people who've recovered from serious Covid and still got vaccinated. I would.

Serological tests have consistently shown that far fewer people have had COVID than have been vaccinated, for instance.

What's a good source of those numbers?

The CDC estimates that 36% of Americans have been infected.
