Optimizing boosters: How COVID mRNA vaccines reshape immune memory after each dose
mRNA vaccines developed against the spike glycoprotein of severe acute respiratory syndrome type 2 coronavirus (SARS-CoV-2), displayed remarkable efficiency in combating coronavirus 19 (COVID-19). These vaccines work by triggering both cellular and humoral immune responses against the spike protein of the virus. Cellular immunity may play a more protective role than humoral immunity to variants of concerns (VOC) against SARS-CoV-2, as it targets the conserved regions of spike protein and possibly cross-reacts with other variants.
Since a single spike epitope is recognized by multiple T-cell clones, the ...
