Dengue infection ranging from mild illness to life-threatening disease is widespread in most tropical and subtropical regions of the world. Infection with any of the four serotypes of dengue virus (DENV-1, DENV-2, DENV-3, and DENV-4) can cause dengue illness. TetraVax-DV-TV005 (referred to as TV005) is a live attenuated recombinant tetravalent dengue virus vaccine developed to protect against all four dengue virus serotypes. This study will evaluate the ability of a single dose of TV005 to protect against infection with rDEN3Δ30, a naturally attenuated DENV-3, given 6 months following vaccination with TV005.~This study will enroll healthy adults with no history of previous flavivirus infection. At Day 0 (study entry), participants will be randomly assigned to receive either the TV005 vaccine or placebo. On Day 180, all participants will receive the rDEN3Δ30 virus. All participants will record their temperature 3 times a day for 16 days after each vaccination. Additional study visits will occur on Days 4, 6, 8, 10, 12, 14, 16, 21, 28, 56, 90, 150, 184, 186, 188, 190, 192, 194, 196, 201, 208, 236, 270, and 360. Study visits will include physical examinations and blood collection.
