Figure 2. Vaccine-induced Ab responses in children who experienced DENV1 breakthrough infections.

Figure 2

Vaccine responses to DENV1 (A) and DENV4 (B) were analyzed in baseline seronegative children who received Dengvaxia and subsequently experienced DENV1 (n = 15) breakthrough infections. (A) DENV1 NAb responses after vaccination were measured without depleting any Ab (Control depleted), after removal of all DENV1-binding Abs (Complete Ab depleted with DENV1 antigen), and after removal of CR Ab (CR Ab depleted using a mix of DENV2 and DENV4 antigens). (B) DENV4 NAb responses after vaccination were measured without depleting any Ab (Control depleted), after removal of all DENV4-binding Ab (Complete Ab depleted with a mix of DENV2 and DENV4 antigens), and after removal of CR Ab (CR Ab depleted using DENV1 antigen). (C) The data were also analyzed to compare the percentages of DENV1 and DENV4 TS NAbs in the children after vaccination. Friedman’s 1-way ANOVA test (A and B) or Wilcoxon’s signed ranks test (C) was used to establish statistical significance.
