Vaccination against COVID-19 induces the differentiation of IgG-producing plasma cells and elicits SARS-CoV-2-specific CD4+ and CD8+ effector T cell responses. Both Memory B and T cells become detectable after primovaccination and are further increased by the administration of a booster dose. B cells with increased breadth and potency are selected and mount a diverse memory repertoire able to respond rapidly to subsequent viral challenge.
