Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The purpose of this study is to evaluate the ability of a single dose of TetraVax-DV-TV003 (TV003) vaccine to protect against infection with rDEN2∆30, an attenuated candidate DENV-2 vaccine.
This study will enroll healthy adults with no history of previous infection with a flavivirus (any of a group of viruses that includes the dengue virus). Participants will be randomly assigned to receive either the TV003 vaccine or placebo vaccine on Day 0 (study entry). At Day 180, all participants will receive an injection of the "challenge" virus, rDEN2∆30, an attenuated (weakened) DENV-2 vaccine. For at least 30 minutes after each vaccination, participants will remain in the study clinic to be monitored for any adverse effects of the vaccines. Participants will record their temperature at least 3 times a day for 16 days after the first and second vaccinations.
In addition to vaccination visits at Day 0 and Day 180, participants will attend study visits at Day 2, 4, 6, 8, 10, 12, 14, 16, 21, 28, 56, 90, 150, 182, 184, 186, 188, 190, 192, 194, 196, 201, 208, 236, 270, and 360. At all study visits, participants will give a medical history and undergo a blood collection; at most study visits, participants will undergo a physical examination. Female participants will have a pregnancy test at select study visits.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
TetraVax-DV-TV003 vaccine
Participants in this arm will receive a single injection of the TetraVax-DV-TV003 vaccine on Day 0 (study entry). On Day 180, participants will receive a single injection of the attenuated rDEN2∆30-7169 virus.
TetraVax-DV-TV003
TetraVax-DV-TV003 is a live attenuated recombinant tetravalent dengue virus vaccine, which will be administered as a 0.5 mL dose containing 10\^3.0 plaque forming units (PFUs) each of DENV-1, DENV-2, DENV-3, and DENV-4. It will be delivered by subcutaneous injection in the deltoid region of the upper arm.
rDEN2∆30-7169
The challenge virus, rDEN2∆30-7169, is a live recombinant attenuated DENV-2 candidate vaccine virus and will be administered as a 0.5 mL dose containing 10\^3 PFUs of rDEN2∆30-7169. It will be delivered by subcutaneous injection in the deltoid region of the upper arm.
Placebo
Participants in this arm will receive a single injection of placebo on Day 0 (study entry). On Day 180, participants will receive a single injection of the attenuated rDEN2∆30-7169 virus.
rDEN2∆30-7169
The challenge virus, rDEN2∆30-7169, is a live recombinant attenuated DENV-2 candidate vaccine virus and will be administered as a 0.5 mL dose containing 10\^3 PFUs of rDEN2∆30-7169. It will be delivered by subcutaneous injection in the deltoid region of the upper arm.
Placebo
The placebo vaccine is the vaccine diluent 1X L-15, which will be administered as a 0.5 mL dose delivered by subcutaneous injection in the deltoid region of the upper arm.

* Available for the duration of the study, approximately 26 weeks after the second dose
* Willingness to participate in the study as evidenced by signing the informed consent document
* Females Only: Female participants of childbearing potential willing to use effective contraception for the duration of the trial.
