Haemophilus influenzae type B epiglottitis after immunization with HbOC conjugate vaccine.
US Food and Drug Administration (USFDA) has licensed four Haemophilus influenzae type B (Hib) vaccines for use in children. Haemophilus influenzae type B is by far the most common pathogen in childhood epiglottitis and it is hoped that with the introduction of the Hib vaccine that a corresponding decrease in epiglottitis cases will be appreciated. ⋯ The incidence of Haemophilus influenzae type B epiglottitis at our regional Children's hospital has decreased since the introduction of the Hib vaccine. Reasons for vaccine failure are postulated.
