Brief summary
This is part of an ongoing effort to develop a satisfactory dengue vaccine: Primary objective: To describe the safety after each vaccination with bivalent and tetravalent formulations of dengue vaccine candidates. To describe the immune response after each vaccination of dengue vaccine.
Detailed description
Subjects will be randomized to five groups to receive assigned vaccines and followed up for 12 months.
