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.
