Study Description
Brief Summary:

Primary objective:

To demonstrate whether or not ZOSTAVAX® at minimum release specification approaching expiry potency elicits an acceptable Varicella-Zoster Virus (VZV) antibody fold rise (measured by glycoprotein Enzyme Linked ImmunoSorbent Assay [gpELISA]) from pre-vaccination to 4 weeks post-vaccination.

Secondary objectives:

To describe the safety profile of ZOSTAVAX® at minimum release specification approaching expiry potency.

Condition or disease Intervention/treatment Phase
Herpes Zoster Biological: ZOSTAVAX® Phase 4

Arms and Interventions

Arm Intervention/treatment
Experimental: All Enrolled
Participants received a single dose (0.65 mL) of shingles (herpes zoster) vaccine (live) ZOSTAVAX® by subcutaneous injection at Visit 1 (Day 0)
Biological: ZOSTAVAX®
One dose (0.65 mL) contains: Varicella-zoster virus, Oka/Merck strain, (live attenuated) not less than 19400 PFU

Outcome Measures

Primary Outcome Measures :
  1. Geometric Mean Titre (GMT) of Varicella Antibodies [ Time Frame: Predose (Day 0) and Day 28-35 Post Dose ]
    Blood samples to determine the GMT of varicella antibodies taken pre-vaccination and again 28 to 35 days post vaccination. Titres determined by glycoprotein enzyme-linked immunosorbent assay (gpELISA).
