Brief Summary
The purpose of this study is to assess the safety of Takeda's Tetravalent Dengue Vaccine Candidate (TDV) (previously DENVax) in healthy adults when given as either a subcutaneous (SC) or intradermal (ID) injection at two dose levels (low and high). The vaccine will be given as two doses 90 days apart. Safety assessments include injection site evaluation and adverse events. The immune response generated after vaccination will be assessed up to 9 months after the first vaccination.

Outcome Measures
Primary Outcomes (4)
Number of Participants With Local Injection Site Reaction by Severity
Solicited local reactions were reported using a participant diary. Pain was categorized as Mild (aware of pain but it does not interfere with daily activity and no pain medication is taken); Moderate (aware of pain; there is interference with daily activity or it requires use of pain medication); Severe (aware of pain and it prevents daily activity), redness was categorized as Mild (greater than \[\>\] 15 millimeter \[mm\]); Moderate as (15-30 mm); Severe (\>30 mm), swelling was categorized as Mild (\<15 mm); Moderate (15-30 mm); Severe (\>30 mm), and itching was categorized as Mild (slight itching at injection site); Moderate (moderate itching at injection extremity); Severe (itching over entire body).
Within 14 days after either of the vaccination given on Day 1 or 90 (Day 14 for first vaccination, Day 104 for second vaccination)
Number of Participants With Systemic Adverse Events (AEs) by Severity
Solicited systemic AEs were reported using a participant diary. Solicited systemic AEs included fever (\>= 37.8°C), headache, muscle pain, joint pain, eye pain, photophobia, fatigue, body rash, nausea, vomiting and other (any other symptom not listed in the diary) and were categorized as Mild: transient symptoms, discomfort noticed but easily tolerated, no interference to normal daily activities; Moderate: marked symptoms, moderate interference with daily activities; Severe: considerable interference with daily activities.
Within 14 days after either of the vaccination given on Day 1 or 90 (Day 14 for first vaccination, Day 104 for second vaccination)
Number of Participants With Solicited Local and Systemic AEs
Within 14 days after either of the vaccination given on Day 1 or 90 (Day 14 for first vaccination, Day 104 for second vaccination)
Number of Participants With Unsolicited Local and Systemic AEs
Baseline up to 30 days after second vaccination (Day 120)
Secondary Outcomes (8)
