We studied the epidemiology of Haemophilus influenzae type b (Hib) infections among children with cancer admitted to Canadian pediatric hospitals. From 1991-2014, 13 cases among children with cancer were identified through active surveillance. Average age was 6.7 years. Six of 7 cases eligible for infant immunization were age-appropriately immunized (vaccine failures). Children with cancer may benefit from booster Hib immunization.
