Invasive<i>Haemophilus influenzae</i>Disease in Utah Children: An 11‐Year Population‐Based Study in the Era of Conjugate Vaccine

Abstract

H. influenzae continues to cause invasive disease in Utah children. Hia is the primary cause of the overall increased incidence of invasive H. influenzae disease and leads to disease similar to Hib. Isolated cases of Hib disease demonstrate a continued reservoir. The success of the Hib conjugate vaccine may therefore be vulnerable to vaccine shortages and refusal of vaccination.
