Severe acute respiratory syndrome coronavirus-2 vaccine-induced B cells aspire to long-lived connections: Tracking B-cell memory over time.

It is vitally important that we understand whether mRNA vaccines are capable of generating high-affinity, longlived immune memory cells to SARS-CoV-2. To this end, a recent study by Ellebedy, Kim and colleagues provide much-needed insight into the production and quality of humoral immune cells generated by the BNT162b2 vaccine.
