          -  Subject with stable renal function, stability defined as:

                  GFR

               -  or in the opinion of the investigator after investigator review of more than the
                  last two creatinine measurements or calculated GFRs.

             allograft transplantation at the time of the first vaccination.

             access site for haemodialysis) in the event acute or chronic dialysis is needed.

               -  has practiced adequate contraception for 30 days prior to vaccination, and

               -  has a negative pregnancy test on the day of the first vaccination, and

                  and for 2 months after completion of the vaccination series.

        Exclusion Criteria:

          -  Any primary kidney disease with a high incidence of recurrent primary kidney disease.

          -  Evidence of recurrent primary kidney disease within the current allograft.

          -  Previous allograft loss secondary to recurrent primary kidney disease.

               -  Multiple kidney transplants are allowed if the reason for a previous allograft's
                  loss is not recurrent primary kidney disease.

          -  More than one organ transplanted (i.e. kidney-liver, double kidney or kidney-other
             organ(s) transplanted).

          -  History of events that, in the opinion of the investigator, may put subject at
             increased risk for chronic allograft dysfunction (e.g. delayed graft function,
             peri-operative complications).

          -  Histologic reports of chronic allograft injury (e.g. transplant glomerulopathy,
             arteriopathy, C4d deposition).

          -  Evidence of significant proteinuria in the opinion of the investigator.

          -  Panel reactive antibody score (PRA or cPRA) that is unknown at the time of transplant.

          -  Any autoimmune or potential immune-mediated disease including primary kidney disease.

          -  Use of anti-CD20 or other B-cell monoclonal antibody agents (e.g., rituximab) as
             induction, maintenance and/or therapeutic immunosuppressive therapy for the prevention
             of allograft rejection within 9 months (274 days) of first dose of study
             vaccine/placebo.

          -  Use of any investigational or non-registered product other than the study vaccine

             during the study period.

          -  Concurrent or planned participation in another clinical study, at any time during the
             study period, which has exposed or will expose the subject to an investigational or a
             non-registered product

          -  Administration or planned administration of a live vaccine within 30 days prior to the
             first dose of study vaccine and ending 30 days after the last dose of study vaccine,
             or, administration or planned administration of a non-replicating vaccine within 8
             days prior to or within 14 days after either dose of study vaccine.

          -  Planned administration during the study of a varicella or HZ vaccine other than the
             study vaccine.

          -  Previous vaccination against HZ or varicella within the 12 months preceding the first

             Pre-vaccination visit.

          -  Evidence or high suspicion, in the opinion of the investigator, of noncompliance or
             nonadherence to use of induction and/or maintenance immunosuppressive therapies.

             untreated malignancy, or systemic infection.

             of the vaccine or study material and equipment.

          -  Any condition which, in the judgment of the investigator, would make intramuscular
             injection unsafe.

          -  Any other condition that, in the opinion of the investigator, might interfere with the
