Brief Summary: The purpose of this study is to evaluate the safety and effectiveness of two different formulations of an investigational dengue vaccine (T-DEN) against a placebo vaccine when two doses are given six months apart to adults and children.
Detailed Description: In this study, children and adults at multiple sites in Puerto Rico will be randomly allocated to receive one of two T-DEN formulations or placebo. Subjects will be stratified by age group (a specific number of subjects in each of 4 age groups \[12 months to 50 years of age\] will be enrolled). The study includes 6 scheduled visits and 4 scheduled venipunctures. Safety follow-up for dengue may require unscheduled visits and venipunctures.\> Multiple DEN virus serotypes are endemic in Puerto Rico and all residents are considered to be at risk for dengue. The results of this phase II study will provide a basis for identifying the vaccine formulations which elicit neutralizing antibodies to all four dengue virus serotypes in a high proportion of vaccine recipients. The most immunogenic and well tolerated candidate formulation identified in this study will be considered for advancement to phase III development.\>
