N1 - 21 N2 - The global spread of SARS-CoV-2 in the spring of 2020 was responsible for significant morbidity and mortality, particularly in elderly, comorbid, or immunocompromised patients, such as hematopoietic stem cell (HSC) allograft recipients. COVID-19 also had a major organizational impact on the French healthcare system. This article first summarizes the impact of COVID-19 on HSC allograft activity (particularly from unrelated donors) in Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM-TC) centers in 2020. We then report on the characteristics of SARS-CoV-2 infections in patients receiving allogeneic HSC transplants, the risk factors for severity and mortality, and the humoral and cellular immune response of these patients to the SARS-CoV-2 vaccine UR - https://shs.cairn.info/journal-hematologie-2023-4-page-247?lang=en ER -
