Summary

The aim of the study was to assess the efficacy of Sanofi Pasteur's CYD dengue vaccine in preventing symptomatic virologically-confirmed dengue cases for dengue-endemic areas of Latin America. Primary Objective: To assess the efficacy of CYD dengue vaccine after 3 vaccinations at 0, 6, and 12 months in preventing symptomatic virologically-confirmed dengue (VCD) cases, regardless of the severity, due to any of the four serotypes in children and adolescents aged 9 to 16 years at the time of inclusion. Secondary Objectives: * To describe the efficacy of CYD dengue vaccine in preventing symptomatic VCD cases after the third dose to the end of the Active Phase, after at least 1 dose, and after 2 doses. * To describe the occurrence of hospitalized VCD cases and the occurrence of severe (clinically severe or as per World Health Organization (WHO) criteria) VCD cases, throughout the Surveillance Expansion Period (SEP) and throughout the trial (from Day 0 until the end of the study). * To describe the antibody response to each dengue serotype after Dose 2, after Dose 3, and 1 and 5 years after Dose 3. * To describe the occurrence of serious adverse events (SAEs), including SAEs of special interest in all participants throughout the trial period.
