COVID-19 antibodies persist at least nine months after infection. 98.8 percent of people infected in February/March showed detectable levels of antibodies in November, and there was no difference between people who had suffered symptoms of COVID-19 and those that had been symptom-free

Even if antibodies go down, you still have memory cells capable of becoming plasma cells to make more antibodies rather rapidly. You also have memory T cells that would wipe out infected cells rather quickly. Immunity isn’t just antibody titers. It’s the easiest thing to measure and the thing that produces the most straightforward kind of immunity, but it’s not the be-all end-all. You could have a very low titer and still be immune.

Honest question: If you got the virus, your body created antibodies – what value does the vaccine have to you at that point? What evidence suggests the antibodies created via one avenue are “better”, or longer lasting than the other?

Finally!! The whole, only vaccinated folks have immunity narrative was really bad for science since nearly everything else we get we have an immunity for after, for at least a while. Don’t get me wrong i’m pro vax, had the J&J shot, and had Covid as well. what was interesting and infuriating was that literally weeks after I had covid people were telling me to get the shot and that I don’t have immunity. I waited 6 months before getting the shot. I was a long hauler with taste issues, hoping the shot helps somehow. Otherwise I would have waited longer.

It’s good news of course, the problem from what I read is someone who got the variant X might not have a good natural immunity against variant Y or Z and might end up getting covid again and/or be contagious.

I’ve heard that some individuals who caught the original SARS virus have immunity to COVID-19. That’s ten years later. Would be interesting to find a study on that.
