- Geometric Mean Fold Rise (GMFR) From Day 1 in Varicella Zoster Virus (VZV) Antibody [ Time Frame: Day 1 (Baseline) and Week 4 postvaccination ] [ Designated as safety issue: No ]Blood samples collected prevaccination on Day 1 and Week 4 postvaccination were analyzed using a glycoprotein enzyme-linked immunosorbent assay (gpELISA) to detect Immunoglobulin G antibody to VZV. The GMFR reports the geometric mean of the ratio of individual participant VZV antibody titers at Week 4 postvaccination / Day 1 (Baseline).
- Geometric Mean Titer (GMT) of VZV Antibody [ Time Frame: Day 1 (Baseline) and 4 weeks postvaccination ] [ Designated as safety issue: No ]Blood samples collected prevaccination on Day 1 and Week 4 postvaccination were analyzed using a gpELISA to detect Immunoglobulin G antibody to VZV
- Percentage of Participants With Clinical Adverse Experiences [ Time Frame: Up to 42 days postvaccination ] [ Designated as safety issue: Yes ]An adverse experience was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of study vaccine, whether or not considered related to the use of the product. Any worsening of a preexisting condition which is temporally associated with the use of the study vaccine is also an adverse experience.
- Percentage of Participants Discontinued Due to Clinical Adverse Experiences [ Time Frame: Up to 42 days postvaccination ] [ Designated as safety issue: Yes ]
