a–f Progression of antibody response (a–c) and vaccination coverage (d–f) determined by SPCE, LPBE, and VNT. Data for group I (a, d), group II (b, e), and group III (c, f) are shown. The arrow indicates the timing of vaccination. Results of SPCE are expressed as PI, while those of LPBE and VNT are expressed as a logarithmic titer. Criteria for positivity by SPCE, LPBE, and VNT are 50%, 1/64 (1.81 log10), and 1/45 (1.65 log10), respectively. The results of average titer are presented as mean ± SD (n = 60). *P < 0.05, **P < 0.01, ***P < 0.001
