Natural immunity doesn’t only last 6 months. Where did you get that? I’m coming out of my second COVID infection now. Long story short, I was in the local hospital and the fact that this was my second infection caused a really big hubbub in the COVID ward and a nurse told me I was the first reinfection she has seen.

You got 180 days before natural immunity wanes and Delta poses a risk of reinfection.

  That's looking at relative risk not overall. It's not saying you lose immunity after 180 days.

    Natural immunity wanes enough to cause a "2nd surge" in cities that were 75%ish infected, such as Araraquara city, Brazil, and Manaus, Brazil. I can agree with you that the 180-days thing is just an estimate from one study. Further studies are needed to narrow down the exact time when natural immunity wanes. But its a good "first guess" at the phenomenon, and should be within a magnitude of the truth. From what we've seen around the world, COVID19 (or at least its variants, like Gamma/P.1 or Delta/B.1.617) is more than willing to reinfect populations in less than a year.

      The Manaus study used a convenience sample, meaning that you cannot infer population rates from it. Who would have thought that reading the abstract of a paper could be a super power?
