Immunity goes away after a while, just like the flu. I had Covid in March of last year and donated antibody-rich plasma but was limited in time to how long I could donate for this very reason. And variants pop up that you don't have immunity to even if you still had antibodies. I'll be 2 weeks post my second dose of Pfizer for this very reason. The most common variant in the US is now B117 (the UK variant), which I did not have, but which the vaccine is effective against. You do NOT want to get Covid-19. Get the vaccine. I still have to use an electronic natural gas detector in our kitchen to check for gas leaks since my sense of smell is still broken. My friend's aunt just died. Her asymptomatic daughter brought Covid-19 to Passover dinner and killed her.
