Comparison of neutralizing antibody titers early and late after vaccination. (A) YFV NT50 values of participants examined 3–4 weeks (N = 20), 4 (N = 20) or 6 years (N = 19) after vaccination. (B) JEV NT50 values of participants tested 3–4 weeks (N = 14) or 0.5–6 years (N = 17) after vaccination. The bars indicate the geometric mean neutralizing antibody titers. The values were compared using the Mann–Whitney U test. p-values indicate the level of significance of differences between groups.
