- Percentages of Participants With Local Reactions By Severity Within 14 Days of Any Vaccination [ Time Frame: Within 14 days ]Local reactions consisted of any pain at the site of injection, any swelling, and any redness. Participants were issued an electronic diary (e-diary) and were asked to monitor and record (according to corresponding grading scales) any local reactions for 14 days following each vaccination. Grading details are as follows: Mild (Pain: did not interfere with activity; Redness and Swelling: 0.5-5.0 centimeters [cm] or 1-10 caliper units), Moderate (Pain: interfered with activity; Redness and Swelling: more than [>] 5.0 to 10.0 cm or 11-20 caliper units), Severe (Pain: prevented daily activity; Redness and Swelling: >10 cm or 21 caliper units and above).
- Percentages of Participants With Systemic Reactions By Severity Within 14 Days of Any Vaccination [ Time Frame: Within 14 days ]Systemic reactions consisted of fever, vomiting, diarrhea, headache, fatigue, muscle pain (other than at the injection site) and joint pain (other than pain adjacent to injection site). Participants were issued an electronic diary (e-diary) and were asked to monitor and record (according to corresponding grading scales) any systemic reactions for 14 days following each vaccination. Grading details are as follows: Mild (Vomiting: 1-2 times in 24 hours; Diarrhea: 2-3 loose stools in 24 hours; Headache, Fatigue, Muscle Pain, Joint Pain: no interference with activity), Moderate (Vomiting: >2 times in 24 hours; Diarrhea: 4-5 loose stools in 24 hours; Headache, Fatigue, Muscle and Joint Pain: some interference with activity), Severe (Vomiting: required intravenous hydration; Diarrhea: more than or equal to [>=] 6 stool in 24 hours; Headache, Fatigue, Muscle and Joint Pain: Significant, prevented daily activity).
- Number of Participants With Treatment-Emergent Adverse Events (TEAEs), Serious Adverse Events (SAEs), and Discontinuations From Treatment Due to TEAEs [ Time Frame: Baseline up to 336 days post study administration or at Early Termination ]An adverse event (AE) was any untoward medical occurrence attributed to study drug in a participant who received study drug. AEs comprised both SAEs and non-SAEs. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Severe TEAEs were those that interfered significantly with the participant's usual function. Causality assessment was made by the investigator.
- Number of Participants With Laboratory Test Abnormalities [ Time Frame: Baseline up to 336 days post last study drug administration or Early Termination ]Number of participants with laboratory test abnormalities without regard to baseline abnormality. Laboratory test parameters included hematology, coagulation, liver function, renal function, electrolytes, hormones, clinical chemistry, immunology urinalysis, urinalysis (dipstick and microscopy), and other tests such as human immunodeficiency virus antibody and hepatitis C antibody.
- Enzyme-Linked Immunosorbent Assay (ELISA) Measured Anti-IgE Geometric Mean Titers (GMTs) at Baseline, Day 182, and Day 336 [ Time Frame: Baseline (Day 1), Day 182 (2 weeks after last vaccination), and end of study (Day 336) ]Ability of vaccine induced serum anti-immunoglobulin E (IgE) antibodies to interfere with IgE binding to recombinant alpha chain of the high affinity IgE receptor was assessed in an ELISA based assay. GMTs were calculated both as crude means (unadjusted) and by an analysis of covariance (ANCOVA) model with natural log transformed antibody titer as outcome variable, and treatment group as factor and baseline (in log scale) as covariates at each of the post dose measurement.
