From: Safety and immunogenicity of a freeze-dried, Vero cell culture-derived, inactivated Japanese encephalitis vaccine (KD-287, ENCEVAC®) versus a mouse brain-derived inactivated Japanese encephalitis vaccine in children: a phase III, multicenter, double-blinded, randomized trial

Figure 2

Changes of mean neutralizing antibody titers before and after vaccination. Satisfactory geometric mean titers (GMTs) were obtained after the second vaccination and before and after the third vaccinations in both vaccine groups, in both homologous and heterologous analyses. The GMTs before the third vaccination in the KD-287 group were higher than those after the second vaccination for both tested strains. After the third vaccination, the neutralizing antibody titer increased in all children, and the GMTs in both groups were higher than the respective GMTs after the second vaccination.
