Cross-neutralizing reactivity of different viral strains of various genotypes to sera taken from 160 individuals. Serum samples from 160 individuals (40 individuals in each age group; 20 individuals in the vaccine group and 20 in the placebo group), from among the 350 subjects who provided a full series of blood samples within the 2-year study period, were collected at 0, 56, and 360 days post-immunization for a cross-neutralization assay with different genotypes of enterovirus 71: A, B (B3–B5), and C (C1–C5). The geometric mean titres are shown above the bar. The bar indicates the 95 % confidence interval
