Title: An Extension Study to Evaluate the Persistence of the Immune Responses Induced by GSK Biologicals Zoster Vaccine, GSK324332A, Administered in Healthy Adult Subjects Aged 18-30 Years and 50-70 Years
Brief Summary: The safety and immunogenicity of the GSK324332A vaccine has been evaluated up to Month 12 post-vaccination in the primary study. In the extension studies presented here, the persistence of the cellular and humoral immune responses will be evaluated 30 and 42 months after the first vaccination in young and elderly adults who received the GSK324332A vaccine. This protocol posting deals only with objectives \& outcome measures of the extension phase at Months 30 and 42. No new recruitment will be done in these extension phases of the primary study. No vaccines are administered in this phase of the study.
