Serological response following BNT162b2 anti‐SARS‐CoV‐2 mRNA vaccination in haematopoietic stem cell transplantation patients.

In G1, all patients, allogeneic recipients and autologous recipients had significantly lower antibody levels than HC, whereas no differences were found in G2. Among the patients vaccinated >5 years after HSCT, allogeneic recipients had antibody titres comparable to HC; in contrast, autologous recipients had significantly lower titres than HC.
