Primary Outcome Measures:
  • Incidence of Confirmed Herpes Zoster (HZ) Cases by Vaccination Group [ Time Frame: 2 Years ] [ Designated as safety issue: No ]
    Incidence rate of HZ cases was defined as the number of confirmed HZ cases per 1000 person-years of follow-up following vaccination. Vaccine efficacy for HZ was defined as the relative reduction in incidence rate of HZ in the group that received Zostavax™ compared with the group that received placebo based on the intent-to-treat population.


Secondary Outcome Measures:
  • Varicella-zoster Virus (VZV) Antibody Response at 6 Weeks Post Vaccination by Vaccination Group [ Time Frame: 6 Weeks ] [ Designated as safety issue: No ]
    VZV antibody response as measured by Glycoprotein Enzyme-Linked Immunosorbent Assay (gpELISA) in the group that received Zostavax™ compared with the group that received placebo, based on the random subcohort population.

  • Number of Participants Reporting One or More Serious Adverse Experiences by Vaccination Group During the 42-day Postvaccination Follow-up Period [ Time Frame: Through 42 days post-vaccination ] [ Designated as safety issue: Yes ]
    A serious adverse event is defined as any adverse event that results in death, is life threatening, results in a persistent or significant disability/incapacity, results in hospitalization or prolongs an existing hospitalization, is a congenital anomaly/birth defect, is a cancer, is an overdose, or is considered an "other important medical event" based on medical judgement.
