- Maximum Age: 15 Months
- Healthy Volunteers: t

Study Arms:
- Cohort A: Dengue Vaccine- Full Dose (T-DEN F17 ) (Type: EXPERIMENTAL): Dengue vaccine at Months 0 and 6 and booster follow-up at 3 years;~DEN candidate vaccine: One dose of the tetravalent, live attenuated DEN vaccine candidate, F17, contains dengue serotype 1, 2, 3 and 4 vaccines. This formulation contains 50 mcg/mL neomycin base, 5.5% lactose, and 1.9 g/dL human serum albumin; for subcutaneous injection. All infants subsequently received an inactivated JE vaccine approximately one and 1.5 months following dengue vaccine dose 2. The licensed JE vaccine in liquid form, was dosed at 0.25 ml for subcutaneous injection.
- Cohort B: Control vaccines (Type: ACTIVE_COMPARATOR): Control vaccines: Hemophilus influenza type b (Hib) vaccine and varicella vaccine
- Cohort C: Dengue Vaccine - 1/10 Dose (T-DEN F17 ) (Type: EXPERIMENTAL): Dengue vaccine at Months 0 and 6 and booster follow-up at 3 years
