Primary Outcome Measures:
  • The Geometric Mean Titer (GMT) of Varicella-zoster Virus (VZV) Antibody at 6 Weeks Postvaccination [ Time Frame: Prevaccination up to 6 weeks postvaccination ]
    Antibody titers were measured by VZV-specific glycoprotein enzyme-linked immunosorbent assay (gpELISA).

  • Geometric Mean Fold Rise (GMFR) in VZV Antibody Titers at 6 Weeks Postvaccination [ Time Frame: Prevaccination up to 6 weeks postvaccination ]
    GMFR was analyzed as the geometric mean of the ratio of VZV antibody titer (gpELISA units/mL) at postvaccination week 6 over VZV antibody titer (gpELISA units/mL) at prevaccination day 1.

  • Number of Participants With Serious Adverse Events [ Time Frame: Up to 42 days postvaccination ]
    A serious adverse event is one that results in death, is life-threatening, results in a persistent or significant disability, results in or prolongs hospitalization, results in a congenital anomaly/birth defect, is a cancer, is an overdose, or is considered an "other important medical event" based on medical judgment.
