摘要:In Canada the introduction of the Haemophilus influenzae type b (Hib) capsular polysaccharide- protein conjugate vaccines in 1988 led to a reduction in the annual incidence of Hib meningitis in children less than 5 years of age from approximately 44/100,000 in 1985 to <1/100,000 by 1994 (1). This reduction in morbidity and mortality was particularly dramatic among the Canadian Inuit, who had suffered the highest reported incidence of Hib meningitis (530/100,000 children less than 5 years) among indigenous populations worldwide (2).International Journal of Circumpolar Health 66:5 2007
