Summary

This Phase 3 trial tested Takeda's dengue vaccine (TDV) in 480 healthy people aged 4 to 60 in India. Participants received two doses of either the vaccine or a placebo, three months apart. The main goals were to check for side effects and measure the body's immune response against all four types of dengue virus.
