| Number of positive sera (%) | ||
| Recombinant protein | IgG | IgM |
| VIR-A4 | 22 (11.0) | 36 (18.1) |
| VIR-B10 | 22 (11.0) | 18 (9.0) |
| VIR-C1 | 23 (11.5) | 12 (6.0) |
| VIR-C2 | 35 (17.5) | 22 (11.0) |
| VIR-C16 | 4 (2.0) | 30 (15.1) |
| VIR-E5 | 20 (10.0) | 26 (13.1) |
| VIR-E8 | 5 (2.5) | 30 (15.1) |

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)
