From Reuters:

In COVID-19 survivors, important components of the body's immune response called memory B cells continue to evolve and get stronger for at least several months, producing highly potent antibodies that can neutralize new variants of the virus, a new study has found. By comparison, vaccine-induced memory B cells are less robust, evolving for only a few weeks and never "learning" to protect against variants, researchers reported in a paper published on Thursday in Nature. COVID-19 vaccines do induce more antibodies than the immune system does after a coronavirus infection. But the immune system response to infection appears to outshine its response to vaccines when it comes to memory B cells. Regardless of whether antibodies are induced by infection or vaccine, their levels drop within six months in many people. But memory B cells stand ready to produce new antibodies if the body encounters the virus. Prior to this study, there had been little data on how vaccine-induced B cells compare to infection-induced B cells. The researchers caution that the benefits of stronger memory B cells after infection do not outweigh the risks that come with COVID-19. "While a natural infection may induce maturation of antibodies with broader activity than a vaccine does, a natural infection can also kill you," said study leader Michel Nussenzweig of Rockefeller University, in a statement. "A vaccine won't do that and, in fact, protects against the risk of serious illness or death from infection."
