Study Details

Study Description

Brief Summary

The aim of the trial was to evaluate the use of a tetravalent vaccine, CYD dengue vaccine, against dengue disease.

Primary Objectives:
  • To describe the humoral immune response to dengue before and after each vaccination with dengue vaccine in two age cohorts of children (6 to 11 years and 2 to 5 years) previously vaccinated with yellow fever (YF) vaccine.

  • To evaluate the safety of each vaccination with dengue vaccine in two age cohorts of children (6 to 11 years and 2 to 5 years).

  • To describe viremia after the first and second vaccinations with dengue vaccine in a subgroup of 130 randomized participants (100 participants in Dengue Vaccine Group and 30 participants in Control Group) in two age cohorts of children (6 to 11 years and 2 to 5 years).

Condition or Disease Intervention/Treatment Phase
  • Biological: CYD Dengue Vaccine Serotypes 1, 2, 3, and 4
  • Biological: Pneumococcal polysaccharide vaccine
Phase 2

Detailed Description

Participants were randomized to receive either three injections of CYD dengue vaccine or two injections of placebo, and one injection of a pneumococcal polysaccharide vaccine (Pneumo23®) at 0, 6, and 12 months, respectively.

Study Design

Study Type:
Interventional
Actual Enrollment :
300 participants
Allocation:
Randomized
Intervention Model:
Parallel Assignment
Masking:
Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Masking Description:
The observer-blind design was implemented. The person who performed vaccinations knew which product was administered while neither the participant nor the Investigator in charge of safety evaluation knew which product was injected. To maintain the blind and minimize any potential bias, the control group used the same route and schedule as the study vaccine.
Primary Purpose:
Prevention

    Adverse Events

    Time Frame Adverse event (AE) data was collected from Day 0 (post-vaccination) up to 28 days post-injection 3. Solicited Reaction (SR) data were collected within 7 and 14 days after vaccination. Serious adverse event (SAE) data were collected throughout the study.
    Adverse Event Reporting Description Analysis was performed on Safety Analysis Set. A solicited reaction is an AE that is prelisted in the electronic case report form (eCRF) and considered to be related to vaccination. A solicited reaction is therefore an adverse drug reaction (ADR) observed and reported under the conditions (nature and time to onset) prelisted in the eCRF. An unsolicited AE is an observed AE that does not fulfill the conditions prelisted in the eCRF in terms of symptom and/or time to onset post-vaccination.
