Condition(s) targeted: Dengue; Dengue Hemorrhagic Fever
Intervention: Live, attenuated, recombinant dengue serotype 1 , 2, 3 , and 4 virus (Biological); NaCl 0.9% (Biological); Tetanus toxoid, reduced diphtheria toxoid, acellular pertussis vaccine adsorbed (Biological); Meningococcal A+C vaccine (Biological)
Phase: Phase 2

Summary
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.
Clinical Details
Official title: Immunogenicity and Safety of CYD Dengue Vaccine in Healthy Children and Adolescents Aged 9 to 16 Years in South America
Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Prevention
Primary outcome: Information concerning the immunogenicity of CYD dengue vaccine after primary vaccination.Information concerning the safety in terms of solicited injection site and systemic reactions, unsolicited adverse events and serious adverse events post-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.
