In Bamako, Mali, where surveillance revealed a high incidence of Haemophilus influenzae type b (Hib) invasive disease, Hib conjugate vaccine was introduced into the Expanded Program on Immunization and the impact assessed. Annual confirmed Hib hospitalizations for infants 0–11 months of age fell from 175/105 to 44/105 (P < 0.001); among infants 6–7 months of age Hib hospitalizations fell from 377/105 to 69/105, (82% decrease, P < 0.001). Invasive Streptococcus pneumoniae hospitalizations remained unchanged. In a baseline serosurvey, only 3/200 infants 6–7 months of age (1.5%) had protective anti-polyribosylribitol phosphate (PRP) titers ≥ 0.15 μg/mL and 1(0.5%) had ≥ 1.0 μg/mL. In serosurveys 18 and 30 months after vaccine introduction, 168/201 (84%) and 184/200 (92%) infants, respectively, had titers ≥ 0.15 μg/mL and 141/201 (70%) and 163/200 (82%) had titers ≥ 1.0 μg/mL. Introduction of Hib vaccine led to rises in anti-PRP seroprevalence, significant reductions in Hib disease, and all-cause hospitalizations, whereas S. pneumoniae disease remained unchanged.
