This should be something we already know. It used to be common knowledge that if infected and recovered you have natural immunity. This is why we don’t walk around in plastic bubbles worried about every damn virus and bacteria in the world. If anyone really looked into it they would be shocked at the viruses and bacteria they come in contact with every moment of their lives.
The study did promote the bogus bullshit of topping off your natural immunity with a vaccine. Adding that bullshit makes me take the entire thing with a grain of salt. Doctors should not be advising you get vaccinated after you’ve recovered from a viral infection. It will only cause your immune system to go into overdrive. Maybe it’s not so dangerous 6 months or a year later but getting vaccinated post-recovery just sounds dangerous to me.
Oh… researchers recommend against having infection parties because the virus can kill you. That was the CYA quote of the story.
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 vaccinated people to get Delta, develop symptoms from it, or become hospitalized with serious COVID-19.
The study demonstrates the power of the human immune system, but infectious disease experts emphasized that this vaccine and others for COVID-19 nonetheless remain highly protective against severe disease and death. And they caution that intentional infection among unvaccinated people would be extremely risky. “What we don’t want people to say is: ‘All right, I should go out and get infected, I should have an infection party.’” says Michel Nussenzweig, an immunologist at Rockefeller University who researches the immune response to SARS-CoV-2 and was not involved in the study. “Because somebody could die.”
Having SARS-CoV-2 once confers much greater immunity than a vaccine—but no infection parties, please | Science | AAAS (sciencemag.org)
