New study finds that mRNA vaccination sustained influenza-specific germinal-center activity for up to six months in some participants

SEOUL, South Korea, Sept. 11, 2026 /PRNewswire/ -- Influenza remains a major global health challenge as continual antigenic drift can limit the breadth and durability of vaccine-induced antibody responses, requiring frequent vaccine updates. Researchers are therefore seeking strategies to generate broader, longer-lasting protection. A key focus is the germinal-center (GC), where B cells undergo selection and somatic hypermutation to produce diverse, high-affinity antibodies and long-lived memory B cells.
