研究概览
简要总结
Primary objectives:
- To describe the immune response to each dengue serotype before and after each vaccination with sanofi pasteur's CYD dengue vaccine.
- To evaluate the safety of each vaccination with sanofi pasteur's CYD dengue vaccine.
详细描述
The antibody levels against each serotype will be measured before and after each vaccination. The subjects will be followed for 28 days after each vaccination for solicited and unsolicited safety parameters. Serious adverse events (SAEs) will be collected throughout the study.

时间窗: Day 0 (before each vaccination) and Day 28 post each vaccination
Neutralizing antibody levels against each of the 4 parental dengue virus strains of Sanofi Pasteur's CYD dengue vaccine constructs were measured using the dengue plaque reduction neutralization test (PRNT). Flavivirus-immune subjects at baseline are defined as those participants with ≥ 10 1/dil for at least one serotype with the parental dengue virus strain or for Yellow Fever titer.
