From: Humoral immunity for durable control of SARS-CoV-2 and its variants
Evolution of humoral immune responses to SARS-CoV-2. Bmem cells evolve their BCRs over time to acquire the breadth to pre-Omicron variants. The BCR breadth is further expanded to Omicron variants after re-exposures by vaccination or infection. These processes may play a pivotal role in durable and broad protection against SARS-CoV-2 variants that emerge in the future. The figure was created with BioRender.com
