Brief Summary
The purpose of this study is to compare the safety, tolerability and immunogenicity of Takeda's Tetravalent Dengue Vaccine Candidate (TDV) \[previously DENVax\] when administered intradermally in varied dosing schedules and via different methods of administration (conventional needle/syringe versus needle-free PharmaJet® injector).

Outcome Measures
Primary Outcomes (9)
Percentage of Participants With Local (Injection Site) Adverse Events (AEs) After Either Vaccine Dose by Maximum Severity as Assessed by the Clinical Staff
An AE is defined as any untoward medical occurrence in a patient or clinical trial participant administered a pharmaceutical product regardless of its causal relationship to the study treatment. Local injection site reactions were evaluated by the blinded clinical staff and include: erythema (redness), edema/induration (swelling), pain and pruritus (itching). Severity grades for erythema and edema are derived based on the Division of Microbiology and Infectious Diseases (DMID) toxicity grading longest diameters using the scale 0=none, 1=\<15 millimeters (mm), 2=15 to 30 mm and 3=\>30 mm (severe). Pain and itching were graded using the scale: 0=none to 4=requires ER visit or hospitalization. Local injection site reactions are presented as the percentage of participants experiencing a reaction, by reaction type, overall and by severity, using the participant's worst reported severity grade. Only categories for which there was at least 1 participant are reported.
28 Days after each dose
Percentage of Participants With Unsolicited Adverse Events (AE) by Maximum Severity
An AE is defined as any untoward medical occurrence in a patient or clinical trial participant administered a pharmaceutical product regardless of its causal relationship to the study treatment. AEs are graded from Grade 0=None to Grade 4=Life threatening. AEs are presented as the percentage of participants experiencing an AE, overall and by severity, using the participant's worst reported severity grade.
28 Days after each dose
Percentage of Participants With Solicited Systemic AEs as Reported by the Participant Using a Memory Aid 14 Days After Either Vaccine Dose by Maximum Severity
An AE is defined as any untoward medical occurrence in a patient or clinical trial participant administered a pharmaceutical product regardless of its causal relationship to the study treatment. Systemic AEs solicited from the participant using a memory aid included: body temperature, headache, myalgia (muscle pain), arthralgia (joint pain), photophobia (sensitivity to light), fatigue (tiredness), body rash, nausea and vomiting. Systemic AEs were graded using the scale: Grade 0= none to Grade 4=Life threatening. Systemic reactions are presented as percentage of participants experiencing a reaction, by reaction type, overall and by severity, using the participant's worst reported severity grade. Only categories for which there was at least 1 participant are reported.
14 days after each dose
Percentage of Participants With Solicited Local AEs as Reported by the Participant Using a Memory Aid 14 Days After Either Vaccine Dose by Maximum Severity
An AE is defined as any untoward medical occurrence in a patient or clinical trial participant administered a pharmaceutical product regardless of its causal relationship to the study treatment. Local injection site AEs solicited from the participant using a memory aid included: erythema (redness), edema/induration (swelling), pain and pruritus (itching). Local injection site reactions are presented as the percentage of participants experiencing a reaction, by reaction type, overall and by severity, using the participant's worst reported severity grade.
14 days after each dose
Percentage of Participants With Unsolicited Vaccine-Related AEs Within 28 Days After Either Vaccine Dose by Maximum Severity
An AE is defined as any untoward medical occurrence in a patient or clinical trial participant administered a pharmaceutical product regardless of its causal relationship to the study treatment. AEs are graded from Grade 0=None to Grade 4=Life threatening. AEs are presented as the percentage of participants experiencing an AE causally related to the study treatment as assessed by the investigator, overall and by severity, using the participant's worst reported severity grade. Only categories for which there was at least 1 participant are reported.
28 Days after each dose
Percentage of Participants With Abnormal Laboratory Values Reported as Adverse Events (AEs)
The percentage of participants with any clinically relevant abnormal safety laboratory values (chemistry, hematology and urinalysis) collected from vaccine dose 1 (Day 0) through 28 days after dose 2 (Day 90) that were reported as AEs. Abnormal laboratory values were reported as AEs based on the following criteria: Grade 3 (Severe) or Grade 4 (Life threatening) laboratory abnormalities based on DMID toxicity tables or laboratory abnormalities which resulted in a medical intervention.
118 Days
Seroconversion Rates (SCR) for Each of the Four Dengue Serotypes After First Injection
Seroconversion rate is defined as the percentage of participants with PRNT50 titer ≥ 10 or, if the titer on Day 0 is greater than 10, a four-fold rise in antibody titer.
Day 28
Seroconversion Rates (SCR) for Each of the Four Dengue Serotypes After Second Injection
Seroconversion rate is defined as the percentage of participants with PRNT50 titer ≥ 10 or, if the titer on Day 0 is greater than 10, a four-fold rise in antibody titer.
Day 118
Percentage of Participants With Unsolicited Vaccine-Related SAEs
A serious adverse event (SAE) is any AE in the view of the investigator that results in any of the following outcomes: death, life threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that may require medical or surgical intervention to prevent one of the other serious outcomes.
Dose 1 until 28 days after Dose 2 (Up to Day 118)
