BACKGROUND: High, or increasing, rates of invasive Haemophilus influenzae (Hi) type a disease have been reported from North American native children from circumpolar regions, raising the question of serotype replacement being driven by vaccination against Hi type b (Hib). Indigenous Australians from remote areas had high rates of invasive Hib disease in the past, comparable to those in North American Indigenous populations.
OBJECTIVE: Evaluate incidence rates of invasive Hi (overall and by serotype) in Indigenous Australian children over time.
DESIGN: Descriptive study of Hi incidence rates by serotype, in the Northern Territory (NT) and South Australia (SA) from 2001 to 2011. Comparison of NT data with a study that was conducted in the NT in 1985-1988, before Hib vaccine was introduced.
RESULTS: The average annual rate of invasive Hi type a (Hia) disease in Indigenous children aged
