- has agreed to continue adequate contraception during the entire treatment period and for 2 months after completion of the vaccination series.
-
Use of any investigational or non-registered product other than the study vaccine within 30 days preceding the first dose of study vaccine, or planned use during the study period.
-
Chronic administration of immunosuppressants or other immune-modifying drugs within six months prior to the first vaccine dose. A prednisone dose of < 20 mg/day is allowed. Inhaled, topical and intra-articular corticosteroids are allowed.
-
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 (E.g. inactivated and subunit vaccines) within 8 days prior to or within 14 days after either dose of study vaccine.
-
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.
-
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 product.
-
Previous vaccination against HZ or varicella.
-
Planned administration during the study of an HZ or varicella vaccine other than the study vaccine.
-
History of HZ.
-
Any confirmed or suspected immunosuppressive or immunodeficient condition resulting from disease or immunosuppressive/cytotoxic therapy.
-
History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccine.
-
Acute disease and/or fever at the time of enrollment.
- Fever is defined as temperature ≥ 37.5°C (99.5°F) on 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 without fever may be enrolled at the discretion of the investigator.
-
Administration of immunoglobulins and/or any blood products within 3 months preceding the first dose of study vaccine or planned administration during the study period.
-
Pregnant or lactating females.
-
Females planning to become pregnant or planning to discontinue contraceptive precautions (if of childbearing potential) before Month 4.
-
Any condition which, in the opinion of the investigator, prevents the subject from participating in the study.
-
Any other condition that, in the opinion of the investigator, might interfere with the evaluations required by the study.
-
Any condition which, in the judgment of the investigator would make intramuscular injection unsafe.

Group Intervention Description HZ/su Lot B Herpes Zoster vaccine (GSK 1437173A) Subjects will receive Lot B of the HZ/su vaccine at 0 and 2 months. The HZ/su vaccine composed of unique randomized combinations of an adjuvant lot and one gE lot. HZ/su Lot A Herpes Zoster vaccine (GSK 1437173A) Subjects will receive Lot A of the HZ/su vaccine at 0 and 2 months. The HZ/su vaccine composed of unique randomized combinations of an adjuvant lot and one gE lot. HZ/su Lot C Herpes Zoster vaccine (GSK 1437173A) Subjects will receive Lot C of the HZ/su vaccine at 0 and 2 months. The HZ/su vaccine composed of unique randomized combinations of an adjuvant lot and one gE lot.
- Primary Outcome Measures
Name Time Method Number of Subjects With Anti-gE Antibody Concentrations Equal to or Above the Cut-off Value At Month 3 Anti-gE antibody concentrations, as determined by Enzyme-linked Immunosorbent Assay (ELISA). The cut-off value was ≥ 97 milli international units per milliliter (mIU/mL).
- Secondary Outcome Measures
Name Time Method Number of Subjects With Any and Grade 3 Solicited Local Symptoms Within 7 days (Days 0-6) after each vaccine dose and across doses Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade. Grade 3 pain = significant pain at rest, that prevented normal every day activities.
Number of Days With Any Solicited General Symptoms During the 7 days (Days 0-6) after each vaccine dose The number of days with any general symptoms reported during the solicited post-vaccination period.
Anti-gE Humoral Immunogenicity At Month 0 and Month 3 Anti-gE antibody concentrations, were determined by ELISA, expressed as Geometric Mean Concentrations (GMCs), in milli international units per milliliter (mIU/mL).
Number of Days With Any Solicited Local Symptoms During the 7 days (Days 0-6) after each vaccine dose The number of days with any local symptoms reported during the solicited post-vaccination period.
Number of Subjects With Any, Grade 3 and Related Unsolicited Adverse Events (AEs) During 30 days (Days 0-29) after each vaccination An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination. Grade 3 AE = an AE which prevented normal, everyday activities. Related = AE assessed by the investigator as related to the vaccination.
Number of Vaccine Responders for Anti-gE Concentrations as Determined by ELISA At Month 3 Vaccine response was defined as: For initially seronegative subjects, antibody concentration at post-vaccination ≥ 4 fold the cut-off for Anti-gE (4x97 mIU/mL); For initially seropositive subjects, antibody concentration at post-vaccination ≥ 4 fold the pre-vaccination antibody concentration.
Number of Subjects With Any Potential Immune-Mediated Diseases (pIMDs) From first vaccination up to 30 days post last vaccination (Month 0-Month 3) and from Month 4 until study end (Month 14) Potential immune-mediated diseases (pIMDs) are a subset of AEs that include autoimmune diseases and other inflammatory and/or neurologic disorders of interest which may or may not have an autoimmune aetiology
Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms Within 7 days (Days 0-6) after each vaccine dose and across doses Assessed solicited general symptoms were fatigue, gastrointestinal (nausea, vomiting, diarrhea and/or abdominal pain), headache, myalgia, shivering and temperature \[defined as oral temperature equal to or above 37.5 degrees Celsius (°C)\]. Any = occurrence of the symptom regardless of intensity grade. Grade 3 symptom = symptom that prevented normal activity. Grade 3 temperature= temperature \> 39.0 °C. Related = symptom assessed by the investigator as related to the vaccination.
Number of Subjects With Any Serious Adverse Events (SAEs) From first vaccination up to 30 days post last vaccination (Month 0-Month 3) and from Month 4 to study end (Month 14) Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity.
