The aim of this study is to evaluate the immunogenicity and safety of the CYD dengue vaccine in India adult subjects. Primary Objectives: - To describe the neutralizing antibody response to each dengue virus serotype before the first vaccination and after each vaccination with CYD dengue vaccine in all subjects. - To describe the safety of the CYD dengue vaccine after each dose in all subjects. Secondary Objective: - To detect symptomatic dengue cases occurring at any time in the trial.
