How common is that? I know there have been a few cases where it's believed to happen, but similarly there are some cases of people getting chicken pox more than once. With chickenpox, that's rare enough that chicken pox is generally considered something that you only get once, but it does happen.
That doesn't answer my question though. What does the data actually say about the covid reinfection rate? I've heard of anecdotes, but haven't seen any numbers.
