PRIMARY outcome

Timeframe: One month post second dose (Day 120)

Population: Per-protocol Set (PPS) excludes all participants seropositive for dengue virus at Baseline and includes all participants in the Full Analysis Set (FAS- who received at least 1 dose of trial vaccine with valid pre-dose and post-dose measurement for immunogenicity assessment) who have no major protocol violations, with data available for analysis.

GMTs of neutralizing antibodies for each of the 4 dengue serotypes were measured by microneutralization test 50% \[MNT50\]. The 4 dengue virus serotypes were DENV-1, DENV-2, DENV-3, and DENV-4.

Population: The PPS excludes all participants seropositive for dengue virus at Baseline and includes all participants in the FAS who have no major protocol violations. Number analyzed is the number of participants with data available for analysis at the given time point.

Seropositivity rate was defined as the percentage of participants being seropositive, derived from titers of dengue-neutralizing antibodies. Seropositivity was defined as a reciprocal neutralizing titer ≥10 (for each serotype). Seropositivity rates were assessed for the four dengue serotypes: DENV-1, DENV-2, DENV-3, and DENV-4.

Seropositivity rate was defined as the percentage of participants being seropositive, derived from titers of dengue-neutralizing antibodies. Seropositivity was defined as a reciprocal neutralizing titer ≥10. The dengue virus serotypes are DENV-1, DENV-2, DENV-3 and DENV-4.
