Outcome Measures

Primary Outcomes (1)

  • Incidence of Confirmed Herpes Zoster (HZ) Cases by Vaccination Group

    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.

    2 Years

Secondary Outcomes (2)

  • Varicella-zoster Virus (VZV) Antibody Response at 6 Weeks Post Vaccination by Vaccination Group

    6 Weeks

  • Number of Participants Reporting One or More Serious Adverse Experiences by Vaccination Group During the 42-day Postvaccination Follow-up Period

    Through 42 days post-vaccination

Study Arms (2)

Zostavax™

EXPERIMENTAL

Participants randomized to receive Zoster Vaccine, Live (Zostavax™).

Biological: Zoster Vaccine, Live (Zostavax™)

Placebo

PLACEBO COMPARATOR

Participants randomized to receive Placebo.

Biological: Comparator: Placebo

Interventions

A single dose 0.65 ml Zostavax™ (Live, attenuated Zoster Vaccine) was administered by subcutaneous injection on Day 1.

Also known as: V211, Zostavax™
Zostavax™

A single dose of 0.65 ml Placebo (A vaccine stabilizer of Zostavax™ with no live virus) was administered by subcutaneous injection on Day 1.
