Germinal centres (gc) are lymphoid structures where B cells acquire affinity-enhancing somatic hypermutations (SHM), with surviving clones differentiating into memory B cells (mbcs) and long-lived bone marrow plasma cells (BMPCs). SARS-CoV-2 mRNA vaccination induces a persistent gc response that lasts for at least six months in humans. The fate of responding GC B cells as well as the functional consequences of such persistence have not been elucidated. we detected SARS-CoV-2 spike (S)-specific MBCS in 42 individuals who had received two doses of BNT162b2, a SARS-CoV-2 mRNA vaccine six months earlier. S-specific IgG-secreting BMPCs were detected in 9 out of 11 participants. Using a combined approach of sequencing the B cell receptors of responding blood plasmablasts and MBCs, lymph node GC and plasma cells and BMPCs from eight individuals and expression of the corresponding monoclonal antibodies (mAbs), we tracked the evolution of 1540 S-specific B cell clones. We show that early blood S-specific plasmablasts – on average – exhibited the lowest SHM frequencies. In comparison, SHM frequencies of S-specific GC B cells increased by 3.5-fold within six months after vaccination. S-specific MBCs and BMPCs accumulated high levels of SHM, which corresponded with enhanced anti-S antibody avidity in blood and affinity as well as neutralization capacity of BMPC-derived mAbs. This study documents how the striking persistence of SARS-CoV-2 vaccination-induced GC reaction in humans culminates in affinity-matured long-term antibody responses that potently neutralize the virus.
