Immunogenicity and safety of ZOSTAVAX(®) approaching expiry potency in individuals aged ≥50 years.
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.
