Immunity conferred by influenza virus vaccine is short-lived. After immunization with inactivated influenza virus vaccine, serum antibody levels peak within a few months and then decline rapidly. This decline was recently shown to be caused by loss of bone marrow plasma cells, a major source of serum antibodies. Results of a recent study partially address …
