Abstract
During the SARS CoV-2 primary infection, the neutralizing antibodies focused against the spike (S) glycoproteins are responsible for blockage of virus-host cell interaction. The cellular response mediated by CD4+ and CD8+ T-cells is responsible for control of viremia.Immune memory against SARS-CoV-2 depends on virus type, replication kinetics and route of penetration. The formation and persistence of germinal centers are critical for the generation of affinity-matured plasma cells and memory B cells capable of mediating durable immunity. They can persist up to 30 weeks after vaccination and several months after infection. Heterogeneity in the longevity of the vaccination-induced GC response is significant.
