Edit: goddamnit, I see this is being downvoted despite being 100% correct. Yes, infections generate strong immunity. Here is a study: https://www.medrxiv.org/content/10.1101/2021.08.24.21262415v...

It is pretty useful though. Studies have found it compares well with vaccines or better.

However like vaccines it also fades. And prior immunity + infection is way better than prior immunity, so being infected no reason not to get vaccinated.



>It is pretty useful though. Studies have found it compares well with vaccines or better.

My understanding was that there were many more studies of vaccine protection than immunity after infection.

Some links to those studies of immunity after infection would be greatly appreciated.


There are more RCTs about vaccination – because of the taboo against human challenge trials, even among the vaccinated.

But there's more evidence for natural immunity, from the 1B+ people worldwide who've had COVID & recovered.
