简要总结

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.
