Adult Immunization: What Can We Learn from the Childhood Immunization Program?

Abstract
Over the past year, the Infectious Diseases Society of America has been developing principles on strengthening adolescent and adult immunization coverage. A summary of those principles is published in this issue of Clinical Infectious Diseases [1], and the complete document is available in the online edition of the journal [2]. We wish to provide personal perspectives on the issue of adult immunization that are based on our collective 26 years of experience directing the immunization program at the Centers for Disease Control and Prevention (CDC; 1977–1987 for A.R.H. and 1988–2004 for W.A.O.).
