Safety and Immune Response to an Investigational Dengue Type 2 Vaccine
Completed · Phase 1 · Has a placebo group
Conditions studied: Dengue Virus
In brief
Dengue viruses can cause dengue fever and other serious health conditions, primarily affecting people living in tropical regions of the world. This study will test whether a vaccine developed to prevent infection with dengue virus type 2 causes a response in people's immune system and is safe.
