Brief Summary
Primary Objectives:
To evaluate safety after each CYD Dengue vaccination in terms of injection site and systemic reactogenicity.
To evaluate the occurrence of Serious Adverse Events (SAEs) throughout the trial period.
To evaluate the humoral immune response to each CYD Dengue serotype after each vaccination in a subset of participants.
Secondary Objectives:
To evaluate the persistence of the humoral immune response during 4 years after the last vaccination in a subset of participants.
Detailed Description
This was a multicenter trial involving three vaccinations one each at 0, 6 and 12 months over a period of 1 year, and a 4-year follow-up following the last vaccination.

Masking Description
An observer-design for the first vaccination and a single-blind design for the second and third vaccination were chosen to minimize the bias of the vaccine evaluation. The Investigator in charge of safety evaluation, the Sponsor, and the participants/parents did not know which vaccine was administrated at the first visit. For the second and third vaccinations, the participants/parents did not know which vaccine was administered.
