Title: Efficacy, Safety, and Immunogenicity Study of GSK Biologicals' Herpes Zoster Vaccine GSK1437173A in Adults Aged 50 Years or Older
Brief Summary: The purpose of this observer-blind study is to evaluate the efficacy, safety and immunogenicity of GSK Biologicals' candidate Herpes Zoster (HZ) vaccine in adults aged ≥ 50 years.

Two studies \[ZOSTER-006 (NCT01165177) and ZOSTER-022 (NCT01165229)\] are being conducted concurrently to evaluate efficacy of GSK1437173A vaccine. A pooled analysis of data from both studies combined will be conducted contingent on each study achieving its objectives. The protocol posting of study ZOSTER-022 also deals with the outcome measures related to the pooled analysis.
