Invasive <EMPH TYPE="ITAL">Haemophilus influenzae</EMPH> Disease in Alaskan Residents Aged 10 Years and Older Before and After Infant Vaccination Programs

Abstract

The overall statewide incidence of invasive H influenzae infections in unimmunized persons aged 10 years and older decreased after the initiation of an infant Hib vaccine program, perhaps by decreasing Hib carriage in child reservoirs. An increase in non-serotype b strains was observed. This trend justifies the need for continued surveillance of invasive disease caused by H influenzae. JAMA. 2000.
