Epidemiology of Invasive Pneumococcal Disease Among High-Risk Adults Since the Introduction of Pneumococcal Conjugate Vaccine for Children

Abstract

Although IPD rates have declined among adults, adults with underlying conditions remain at increased risk of IPD and comprise a larger proportion of adult IPD cases in 2009 compared with 2000. A continued increase in the prevalence of diabetes among US adults could lead to increased burden of pneumococcal disease.
