Study Arms:
- High-dose Tetravalent Dengue Vaccine (HD-TDV) (Type: EXPERIMENTAL): High-dose Tetravalent Dengue Vaccine \[HD-TDV\], 0.5 mL, subcutaneous injection on Day 1. TDV comprised one molecularly-characterized and cloned TDV-2 live attenuated dengue virus strain and three recombinant live attenuated dengue virus strains: TDV-1, TDV-3 and TDV-4. TDV contained 2\*10\^4 plaque forming units (PFU), 5\*10\^4 PFU, 1\*10\^5 PFU, and 3\*10\^5 PFU of TDV-1, TDV-2, TDV-3 and TDV-4 respectively.
