Gedetailleerde beschrijving
The vaccine tested in this study was tetravalent dengue vaccine (TDV). TDV was tested to assess the safety and immunogenicity in healthy adolescents in non-endemic area(s) for dengue.
The study enrolled 400 healthy participants. Participants were randomized in 3:1 ratio to receive:
- TDV 0.5 mL subcutaneous injection
- Placebo normal saline solution (0.9% NaCl) for injection.
In each trial group, participants received 2-dose schedule of TDV or placebo by subcutaneous injection on Days 1 (Month 0) and 90 (Month 3), but not all participants received both doses (8 subjects discontinued the trial before receiving the second dose).
This multi-center trial was conducted in Mexico. The overall time to participate in this study was 270 days. Participants had multiple visits to the clinic including a final visit at Day 270.
