Efficacy and Safety of Dengue Vaccine in Healthy Children

Summary

The primary objective of the study was to assess the efficacy of CYD dengue vaccine after three injections in preventing symptomatic virologically-confirmed dengue (VCD) cases, regardless of the severity, due to any of the four serotypes in children aged 4 to 11 years at the time of inclusion. Secondary objectives included to assess: * Vaccine efficacy against severe VCD cases * Vaccine efficacy against VCD cases following at least two injections with CYD dengue vaccine * Immune response to CYD dengue vaccine * Safety profile of CYD dengue vaccine. Safety assessments include solicited reactions within 7 or 14 days after each injection, unsolicited adverse events within 28 days after each injection, and serious adverse events during the study period. Other objectives included: * Vaccine efficacy against VCD cases following at least one injection with CYD dengue vaccine * Vaccine efficacy against VCD cases due to each serotype * Participants with clinical signs and symptoms for VCD
