Dödligt virus från Kina orsakar panik (SARS-CoV-2, COVID-19)

We argue that natural immunity provides for the type of durable, robust, full, comprehensive protection needed, and is much more robust than immunity induced by vaccination alone. Researchers have shown that the components of immune memory (memory B cells, CD8+ T cells, and CD4+ T cells) in persons who had been exposed to SARS-CoV-2 persist for some time post-infection. Some have argued immunity may last for months, years, decades, or even a lifetime. This important immunity research has emerged by Shane Crotty’s lab in La Jolla California, Lauren Rodda’s group, as well as evidence in Iceland and the US. For example, researchers found antibodies even in milder cases, and that there were antibodies with the capacity to neutralize the virus and antibodies specific to the spike protein. They also reported that the production of antibodies was greater in more severe disease. The NIH reports that “This long-term immune protection involves several components. Antibodies—proteins that circulate in the blood—recognize foreign substances like viruses and neutralize them. Different types of T cells help recognize and kill pathogens. B cells make new antibodies when the body needs them. All of these immune-system components have been found in people who recover from SARS-CoV-2, the virus that causes COVID-19.” This is indeed very good news and helps make our argument, our prognostication, on why persons recovered from infection are vaccine exempt.
