March 10, 2022 updated by: Sanofi Pasteur, a Sanofi Company
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.

Detailed Description
Participants in the Dengue Vaccine Group will receive 3 vaccinations with CYD Dengue vaccine.
Participants in the Control Group will receive placebo vaccinations for the first 2 vaccinations, followed by tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccine adsorbed (ADACEL®) (in Venezuela) or Meningococcal A+C vaccine (in Brazil) as a way of providing therapeutic benefit to the participants in the control group.
