In recent years, increased emphasis has been placed on immunization of adults. The reintroduction of the pneumococcal vaccine in 1976 seems to have begun a new era in adult medicine that targets certain vaccines toward adults. Prior to this, most of our efforts at immunization in the US were directed toward young children. Although the pneumococcal vaccine has been underutilized, publications from the CDC and the American College of Physicians suggest that this particular public health strategy will be with us for some time to come.
