A study claimed that natural Covid-19 infection produces a stronger secondary immune response than the vaccine. The researchers of the study caution that the benefits of stronger memory B cells after infection do not outweigh the risks that come with Covid but Covid vaccines do induce more antibodies than the immune system does after a Covid infection. Memory B cells continue to evolve and get stronger for at least several months and if the effect is replicated in children who are unlikely to develop Covid symptoms, it raises the prospect that they could be better protected by natural immunity than vaccination producing highly potent antibodies that can neutralise new variants of the virus. Also, their data suggest that clinical characteristics of Covid due to the Delta variant in children are broadly similar to Covid due to other variants.
