Brief summary

The purpose of this study was to demonstrate that different CYD dengue vaccine lots manufactured using the same method and in the same location but at different times produce an equivalent immunological response after 3 doses. Primary Objective * To demonstrate that three different Phase III lots of CYD dengue vaccine induce an equivalent immune response in terms of post-Dose 3 geometric mean titers (GMTs) against the four parental serotypes. Secondary Objectives: * To demonstrate that data from one Phase II lot and pooled data from Phase III lots of CYD dengue vaccine show an equivalent immune response in terms of post-Dose 3 GMTs against the four parental serotypes. * To describe the safety of the CYD dengue vaccine in all participants after each dose.

Detailed description

All participants received 3 doses of their assigned vaccine or placebo and provided blood samples at defined timepoints for flavivirus status and immunogenicity assessment. Safety data were collected in all participants after each dose and throughout the study.

Post-Dose 3 Geometric Mean Titers (GMTs) of Antibodies Against Each of the Four Dengue Virus Serotypes Following Vaccination With Phase III Lots of CYD Dengue Vaccine

GMTs against each of the 4 serotypes (serotype 1, serotype 2, serotype 3 and serotype 4) of dengue virus strains were assessed using the plaque reduction neutralization test (PRNT) assay. The lot-to-lot consistency between 3 Phase III lots was based on the use of the two-sided 95% confidence interval (CI) of the differences of the means of the log10 transformed post-vaccination titers between pairs of lots.

Time frame: 28 days post-injection 3

Population: Analysis was performed on Per-protocol analysis set which included participants who received at least 1 dose of the study vaccine or placebo and had no protocol deviations. Data for this outcome measure was not planned to be collected and analyzed for Phase II Lot and placebo.
