Graft-versus-host disease (GVHD) is a major risk factor for prolonged humoral immunodeficiency and vaccine unresponsiveness after allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, the underlying mechanisms for this immunodeficiency are poorly understood. In this article, we describe previously overlooked impacts
