We determined the seroprevalence of protective antibodies against Hib in Mexican children under the age of five using a standardized enzyme-linked immunosorbent assay. Hib antibodies (≥ 0.15 μg/ml) were present in 95.34% (±1.14% [seroprevalence ± standard error]) of samples. Fewer children aged 30 to 47 months had protective Hib antibody levels (91.45% ± 2.60%) than children from 12 to 29 and 48 to 59 months (97.3% ± 1.34% and 97.44% ± 1.80%, respectively).
