Summary

The primary objective of this study is to compare the dengue virus-neutralizing antibody geometric mean titers (GMTs) for each of the 4 dengue serotypes (DENV1, DENV2, DENV3, and DENV4) at Day 28 post-vaccination for participants administered the V181 Low-Potency Level vaccine versus the V181 Mid-Potency Level vaccine. This study will also evaluate the safety and tolerability of 3 different V181 potency level vaccines. The primary hypothesis of the study is that the V181 Low-Potency Level vaccine is non-inferior to the V181 Mid-Potency Level vaccine for each of the 4 dengue serotypes based on GMTs at Day 28 post-vaccination.
