The scientific literature collected here establishes unequivocally that protective immunity following natural infection with SARS-CoV-2 is robust, durable and long-lasting. The underlying immunology is clear with repeated examples of recovered persons producing durable antibodies, memory B cells, and durable polyfunctional CD4+ and CD8+ T cells, as well as bone-marrow plasma cells that produce antibodies as needed with re-exposure, targeting multiple targets on the COVID-19 virus. In total, the evidence is clear that immunity persists in persons who have cleared the virus and recovered.
