Clinical Trial: TDENV PIV and LAV Dengue Prime-boost Strategy
Study Status: Completed
Recruit Status: Completed
Study Type: Interventional
Official Title: A Phase 1, Randomized, Open-label, Single-center, Study of TDENV-PIV and LAV Dengue Vaccine Platforms as Part of a Heterologous Prime-boost Strategy in Healthy Adults in a
Brief Summary: The potential synergistic effect of administering 2 dengue vaccine candidates that were previously shown to be safe and immunogenic in humans will be evaluated in this study. A prime-boost study of tetravalent dengue virus purified inactivated vaccine (TDENV-PIV) with alum and tetravalent dengue live attenuated virus (TDENV-LAV) vaccine Formulation 17 (F17) will gather data to help better understand the human immune response to dengue vaccination and infection.
