• Chronic administration (defined as > 14 consecutive days) of immunosuppressants or other immune-modifying drugs within six months prior to the first vaccine dose. For corticosteroids, a prednisone dose of <20 mg/day, or equivalent, is allowed. Inhaled, topical and intra-articular corticosteroids are allowed.
• Administration of long-acting immune-modifying drugs within six months prior to the first vaccine dose or expected administration at any time during the study period.
• Administration or planned administration of a live vaccine in the period starting 30 days before 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.
• Concurrently participating in another clinical study, at any time during the study period, in which the subject has been or will be exposed to an investigational or a non-investigational vaccine/product.
• Previous vaccination against VZV or HZ and/or planned administration during the study of an HZ vaccine other than the study vaccine.

• History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccine/product.

• Acute disease and/or fever at the time of enrolment.

  • Fever is defined as temperature ≥ 37.5°C /99.5°F for oral, axillary or tympanic route, or ≥ 38.0°C /100.4°F on rectal route. The preferred route for recording temperature in this study will be oral.
  • Subjects with a minor illness (such as mild diarrhoea, mild upper respiratory infection) without fever may, be enrolled at the discretion of the investigator.
• Administration of immunoglobulins and/or any blood products within the 3 months preceding the first dose of study vaccine or planned administration during the study period.
