  1. The percentage of responders was calculated as described in the Methods section. Serum samples were tested at a dilution of 1:100. The cut-off values for each recombinant protein were: VIR-A4, 0.166; VIR-B10, 0.121; VIR-C1, 0.119; VIR-C2, 0.136; VIR-C16, 0.183; VIR-E5, 0.116; VIR-E8, 0.251; AMA-1, 0.341; MSP119, 0.192 (for IgG). VIR-A4, 0.165; VIR-B10, 0.099; VIR-C1, 0.204; VIR-C2, 0.190; VIR-C16, 0.138; VIR-E5, 0.143; VIR-E8, 0.150 (for IgM)
