Persistence of Varicella-Zoster Virus-Specific Plasma Cells in Adult Human Bone Marrow following Childhood Vaccination Journal Article

Overview

Childhood varicella-zoster virus (VZV) immunization induces immune memory responses that protect against primary VZV infection, chicken pox. In the United States, routine childhood VZV vaccination was introduced only 2 decades ago. Hence, there is limited information on the longevity of B and CD4 T cell memory, which are both important for protection. Here, we showed in 15 healthy young adults that VZV-specific B and CD4 T cell responses are detectable in bone marrow (BM) and blood up to 20 years after vaccination. Specifically, we measured antibody-secreting plasma cells in the BM and VZV-specific CD4 T cells in BM and blood. These findings suggest that childhood VZV vaccination induces long-lived immunity.
