The science that the mandates ignore.
From the article you linked:
“…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.’”
“Still, [Charlotte] Thålin [a physician and immunology researcher at Danderyd Hospital and the Karolinska Institute] and other researchers stress that deliberate infection among unvaccinated people would put them at significant risk of severe disease and death, or the lingering, significant symptoms of what has been dubbed Long Covid. The study shows the benefits of natural immunity, but ‘doesn’t take into account what this virus does to the body to get to that point,’ says Marion Pepper, an immunologist at the University of Washington, Seattle.”
“No one in the study who got a new SARS-CoV-2 infection died—which prevented a comparison of death rates but is a clear sign that vaccines still offer a formidable shield against serious disease, even if not as good as natural immunity. Moreover, natural immunity is far from perfect. Although reinfections with SARS-CoV-2 are rare, and often asymptomatic or mild, they can be severe.”
