title: Failure to respond to influenza vaccine in the aged: correlation with B-cell number and function.
abstract: Failure to respond to influenza vaccination correlated with a decreased number and percentage of IgD-bearing PBL and a dampened lymphocyte response to PWM in a subset of healthy aged volunteers. These subjects had normal levels of serum immunoglobulins, intact T cell function, and normal numbers of E-rosetting cells.
