ADVP005; Dengue CVD 12000 - Dengue-1-Virus Live Virus Human Challenge (DENV-1-LVHC)

The purpose of this research study is to test the protection of volunteers previously vaccinated with Tetravalent Dengue Virus (TDEN) Purified Inactivated Vaccine (PIV) with alum and boosted with TDEN live attenuated vaccine (LAV) formulation against a weakened form of an experimental dengue virus challenge. The Investigators will also include people that have not received the study vaccine. The Investigators are collecting information about how the vaccine protects against a dengue virus challenge as well as adding to knowledge about the safety of the challenge. The information will help Investigators develop vaccines to protect people from dengue. Participation is voluntary. The duration of participation will last for 180 days (six months). After participants are exposed to the weakened dengue virus, the Investigators will follow them closely to measure their symptoms. Like the flu, participants might expect to have a headache, rash, body aches, fever and chills or they may experience no symptoms whatsoever. If a participant does develops symptoms, the Investigators will monitor him/her closely in a local hotel or a wing of our hospital to ensure safety and to treat symptoms if they occur. Participants will be compensated for their time.
