GMTs were assessed for the four dengue serotypes: DENV-1, DENV-2, DENV-3, and DENV-4, by microneutralization test \[MNT\].

Seropositivity rate was defined as the percentage of participants being seropositive, derived from titers of dengue-neutralizing antibodies. Seropositivity was defined as a reciprocal neutralizing titer ≥10 (for each serotype). Seropositivity rates were assessed for the four dengue serotypes: DENV-1, DENV-2, DENV-3, and DENV-4.

GMTs of neutralizing antibodies were measured by microneutralization test 50% \[MNT50\] for each of the 4 Dengue Serotypes. The 4 dengue virus serotypes were DENV-1, DENV-2, DENV-3 and DENV-4. Data reported for up to Month 48 was collected at Months 1, 3, 6, 12, 13, 18, 24, 36 and 48.
Erythema and Edema Were Graded Per The FDA Guidance for Industry: Toxicity Grading Scale for Healthy Adult and Adolescent Volunteers Enrolled in Preventive Vaccine Clinical Trials. Where Grade 0=none to Grade 4=Severe. Pain and Itching were graded using Common Terminology Criteria for Adverse Events (CTCAE) 4.03 where Grade 0=no pain or itching to Grade 4= Life-threatening/severe. Only those score categories for which there was at least 1 participant are reported.
An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (eg, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug.

An AE can therefore be any unfavorable and unintended sign (eg, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. Some AEs are automatically considered related because of temporal relationship to vaccination.
Rate of seroconversion was defined as the percentage of participants with Plaque Reduction Neutralization Test titer resulting in 50 % reduction in Plagues (PRNT50) titer ≥ 10 for participants seronegative at Baseline or a greater than four-fold increase in PRNT50 for participants seropositive at Baseline.
