The aim of the trial was to evaluate the use of a tetravalent vaccine, CYD dengue vaccine, against dengue disease. Primary Objectives: * To describe the humoral immune response to dengue before and after each vaccination with dengue vaccine in two age cohorts of children (6 to 11 years and 2 to 5 years) previously vaccinated with yellow fever (YF) vaccine. * To evaluate the safety of each vaccination with dengue vaccine in two age cohorts of children (6 to 11 years and 2 to 5 years). * To describe viremia after the first and second vaccinations with dengue vaccine in a subgroup of 130 randomized participants (100 participants in Dengue Vaccine Group and 30 participants in Control Group) in two age cohorts of children (6 to 11 years and 2 to 5 years).
