Study of CYD Dengue Vaccine in Healthy Children and Adolescents in South America
Immunogenicity and Safety of CYD Dengue Vaccine in Healthy Children and Adolescents Aged 9 to 16 Years in South America
The purpose of this study is to generate immunogenicity and safety data in preparation for efficacy studies in Latin America.
Primary Objectives:
- To describe the immune response to dengue viruses before and after each vaccination with CYD dengue vaccine.
- To evaluate the safety of each vaccination with CYD dengue vaccine.

- Known or suspected congenital or acquired immunodeficiency, immunosuppressive therapy such as anti-cancer chemotherapy or radiation therapy within the preceding 6 months, or long-term systemic corticosteroids therapy
- Known systemic hypersensitivity to any of the components of any of the trial vaccines or history of a life-threatening reaction to any of the trial vaccines or to a vaccine containing any of the same substances
- Chronic illness at a stage that could interfere with trial conduct or completion, in the opinion of the Investigator
- Current alcohol abuse or drug addiction that may interfere with the participant's ability to comply with trial procedures
