An AE was any untoward medical occurrence in a participant administered study vaccine and which did not necessarily have a causal relationship. An unsolicited AE was an observed AE that did not fulfill the conditions pre-listed in the protocol and case report form (CRF) in terms of diagnosis and/or onset window post-vaccination.

An AE was any untoward medical occurrence in a participant administered study vaccine and which did not necessarily have a causal relationship. A solicited reaction was an expected adverse reaction (AR) observed and reported under the conditions pre-listed in the protocol and CRF and included pain, erythema, and swelling. Injection site reaction was an AR at and around the injection site. Injection site reactions were commonly inflammatory reactions.

A solicited reaction was an "expected" adverse reaction (sign or symptom) observed and reported under the conditions (nature and onset) pre-listed in the protocol and CRF. Solicited systemic reactions included headache, fever, localized or topical manifestations that were not associated with the vaccination or administration site.

An unsolicited AE was an observed AE that did not fulfill the conditions pre-listed in the protocol and CRF in terms of diagnosis and/or onset window post-vaccination. An AESI was one of scientific and medical concern specific to the study vaccine, for which ongoing monitoring, and rapid communication by the Investigator to the Sponsor was appropriate. The following were considered as serious AESI: serious hypersensitivity/allergic reactions occurring in all participants within 7 days after vaccination; serious viscerotropic disease occurring in all participants within 30 days after vaccination; serious neurotropic disease occurring in all participants within 30 days after vaccination; serious dengue disease requiring hospitalization occurring in all participants at any time during the study. The following were considered as non-serious AESIs, hypersensitivity/allergic reactions occurring in all participants within 7 days after vaccination.

An AE was any untoward medical occurrence in a participant administered study vaccine and which does not necessarily have a causal relationship. SAEs were any untoward medical occurrence that at any dose: resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect, was a medically important event. Hospitalized VCD cases were defined as an acute febrile illness with diagnosis of dengue requiring hospitalization. The confirmatory dengue diagnosis was performed through virological detection.

GMTs of antibodies against each of the 4 dengue virus serotype (parental strains) were assessed using the plaque reduction neutralization test (PRNT).

GMTs of antibodies against each of the 4 dengue virus serotypes (1, 2, 3, or 4) were assessed using plaque reduction neutralization test (PRNT) assay method. Titers were measured in terms of 1/dilution. Dengue seropositive participants at Baseline was defined as participants with titers \>=10 (1/dilution) for at least 1 serotype with parental dengue virus strains. Per-protocol analysis set (PPAS) included all participants who had no protocol violations; and who met any of following study violations were excluded from PPAS (STAGE I/II): had not met all protocol-specified inclusion/exclusion criteria, had not received correct doses or injections, received vaccine other than randomized schedule, did not receive vaccination in proper time window, had not provided post-dose serology sample in proper time window, received protocol-restricted medication, therapy, or vaccine.

GMTs of antibodies against each of the 4 dengue virus serotypes (1, 2, 3 or 4) were assessed using the PRNT assay method. Titers were measured in terms of 1/dilution. Dengue seropositive participants at Baseline were defined as participants with titers \>=10 (1/dilution) for at least one serotype with the parental dengue virus strains. Data of Group 1 (28 days post-dose 3 in STAGE-I) and Group 1a (28 days 12 months Booster dose) were reported and compared in this outcome measure. GMT paired ratio (given in statistical analysis section) was calculated by dividing geometric mean values of Group 1a: 28 days post 12 months booster dose in STAGE-II by Group 1: 28 days post-dose 3 in STAGE-I.
