Outcome Measures

Primary Outcomes (1)

  • Vaccine-related Serious Adverse Experiences (SAEs) for 28 Days Postvaccination

    SAEs are AEs at any dose that: Results in death or persistent/significant disability/incapacity; or prolongs an existing inpatient hospitalization or Is life threatening; or Is a congenital anomaly/birth defect; or Is a cancer; or Is an overdose or Is an other important medical event

    To Day 28 postvaccination

Secondary Outcomes (2)

  • Geometric Mean Titer (GMT) of Varicella-zoster Virus (VZV) Antibody Responses at 4 Weeks Postvaccination

    4 weeks postvaccination

  • Geometric Mean Fold Rise (GMFR) in VZV Antibody Titers From Prevaccination to 4 Weeks Postvaccination

    From prevaccination (baseline) to 4 weeks postvaccination
