The natural immune protection that develops after a SARS-CoV-2 infection offers considerably more of a shield against the Delta variant of the pandemic coronavirus than two doses of the Pfizer-BioNTech vaccine, according to a large Israeli study that some scientists wish came with a “Don’t try this at home” label. The newly released data show people who once had a SARS-CoV-2 infection were much less likely than never-infected, vaccinated people to get Delta, develop symptoms from it, or become hospitalized with serious COVID-19.
So, there you have it. This isn’t some out there on the edge publication. This is the AAAS—

They’re reiterating what many, including me, have been saying for months. My wife, son, and I had the first COVID19 strain and we have antibodies. Moreover, we will likely have lifelong immunity.

The presence in the bone marrow of long-lived, antibody-secreting memory plasma cells is probably the best available predictor of long-lasting immunity. For SARS-CoV-2, most studies so far have analysed the acute phase of the immune response, which spans a few months after infection, and have monitored T cells, B cells and secreted antibodies7. It has remained unclear whether the response generates long-lived memory plasma cells that secrete antibodies against SARS-CoV-2.
