Title: Consistency, Immunogenicity and Safety Study of GSK Biologicals' Herpes Zoster Vaccine GSK1437173A in Adults 50 Years of Age or Older
Brief Summary: The purpose of this study is to demonstrate lot-to-lot consistency in terms of immunogenicity, and evaluate safety of the Herpes Zoster subunit (HZ/su) vaccine. The study is designed as a randomized, double-blind study with three parallel groups.


Options:
A: Inclusion Criteria:

* Subjects who, in the opinion of the investigator, can and will comply with the requirements of the protocol.
* A male or female aged 50 years or older at the time of the first vaccination.
* Written informed consent obtained from the subject.
* Female subjects of non-childbearing potential may be enrolled in the study.

  * Non-childbearing potential is defined as pre-menarche, current tubal ligation, hysterectomy, ovariectomy or post-menopause.
* Female subjects of childbearing potential may be enrolled in the study, if the subject:

  * has practiced adequate contraception for 30 days prior to vaccination, and
  * has a negative pregnancy test on the day of vaccination, and
  * has agreed to continue adequate contraception during the entire treatment period and for 2 months after completion of the vaccination series.

Exclusion Criteria:

* 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.
B: Inclusion Criteria:

* Adults 60 years of age and older.
* History of Chickenpox.
* Have given written informed consent prior to enrollment.
* History of varicella or long-term (greater than or equal to 30 years) residence in the continental USA.

Exclusion Criteria:

* No history of shingles, no current history of immune suppression (e.g. malignancy or neoplastic disease, corticosteroid therapy).
* No immunosuppression resulting from disease (e.g., malignancy; HIV infection), corticosteroids (except intermittent topical or inhaled corticosteroid \[greater than 800 mcg/day beclomethasone dipropionate or equivalent\]), or other immunosuppressive/cytotoxic therapy (cancer chemotherapy or organ transplantation).
* No active neoplastic disease (except local skin cancer or other malignancies \[e.g., prostate cancer\] that are stable in the absence of immunosuppressive/cytotoxic therapy).
* No prior Herpes Zoster.
* No prior receipt of varicella vaccine.
* No allergic sensitivity to neomycin.
* No history of anaphylactoid reaction to gelatin.
* No significant underlying illness that would be expected to prevent completion of the study (e.g., life-threatening disease likely to limit survival to less than 5 years).
* Not ambulatory (must not be bed-ridden or homebound).
* No receipt of immune globulin or any other blood product within 3 months before or planned during the 3-5 year study period.
* No receipt of any other immunizations within one month before study vaccination (2 weeks in the case of inactivated influenza vaccines or other non-replicating immunization products \[e.g., dT, pneumococcal vaccine, hepatitis A vaccine, hepatitis B vaccine\]), or scheduled within 6 weeks after study vaccination.
* Not currently receiving antiviral therapy.
* No other condition (e.g., extensive psoriasis, chronic pain syndrome, cognitive impairment, severe hearing loss) that, in the opinion of the investigator, might interfere with the evaluations required by the study.
* No intercurrent illness (e.g., urinary tract infection, influenza) that might interfere with the interpretation of the study.
* No females who are pre-menopausal.
* No subjects unlikely to adhere to protocol follow-up.
* No subjects involved in a conflicting (vaccine or investigational drug) clinical trial.
C: Inclusion Criteria:

* Subjects who the investigator believes that they can and will comply with the requirements of the protocol should be enrolled in the study;
* Subjects who successfully completed the primary study and who did not receive Varilrix in the primary study;
* Written informed consent obtained from the subject;
* Free of obvious health problems as established by medical history and clinical examination before entering into the study.

Exclusion Criteria:

* Use of any investigational or non-registered product (drug or vaccine) within 1 month preceding the study start, or planned use during the study period;
* Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs within three months prior to the first study procedure, including corticosteroids, except inhaled and topical steroids are allowed;
* Administration or planned administration of a vaccine not foreseen by the study protocol within 2 weeks before the first study procedure, with the exception of the Influenza vaccine, which can be administered 1 week preceding the first study procedure;
* Previous vaccination against HZ, except the study vaccine administered in the primary study;
* History of HZ (shingles);
* Any confirmed or suspected immunosuppressive or immunodeficient condition based on medical history and physical examination;
* Administration of immunoglobulins and/or any blood products within the 3 months preceding the first study procedure or planned administration during the study period.
