Title: Immunogenicity and Safety Study of GSK Biologicals' Herpes Zoster Vaccine GSK1437173A When Co-administered With GSK Biologicals' Seasonal Influenza Vaccine GSK2321138A in Adults Aged 50 Years and Older
Brief Summary: The purpose of this study is to assess immunogenicity, reactogenicity and safety of GSK Biologicals' HZ/su vaccine when its first dose is co-administered with the FLU-D-QIV vaccine in adults aged 50 years or older compared to administration of vaccines separately.


Options:
A: Inclusion Criteria:

* Subjects who, in the opinion of the investigator, can and will comply with the requirements of the protocol (e.g. completion of the diary cards, return for follow-up visits).
* A male or female aged 50 years or older, at the time of the first vaccination with the study vaccine(s).
* 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 (drug or vaccine) other than the study vaccines within 30 days preceding the first dose of study vaccine, or planned use during the study period.
* Chronic administration (defined as more than 14 consecutive days) of immunosuppressants or other immune-modifying drugs within six months prior to the first vaccine dose (for corticosteroids, this will mean prednisone ≥ 20 mg/day, or equivalent). A prednisone dose of \< 20 mg/day is allowed. Inhaled, topical and intra-articular corticosteroids are allowed.
* Administration or planned administration of a vaccine not foreseen by the study protocol within the period starting 30 days before the first dose of study vaccine(s) (HZ/su and/or FLU-D-QIV vaccines) and ending 30 days after the last dose of HZ/su vaccine.
* Administration of an influenza vaccine during the six months preceding entry into the study or planned administration up to the last blood sampling with the exception of the FLU-D-QIV vaccine given during this study.
* Administration of long-acting immune-modifying drugs (e.g. infliximab) 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 vaccine/product (pharmaceutical product or device).
* Previous vaccination against VZV or HZ and/or planned administration during the study of a VZV or HZ vaccine (including an investigational or non-registered vaccine) other than the study vaccine.

* History of any reaction or hypersensitivity likely to be exacerbated by any component of the vaccines.
* History of Guillain Barré syndrome.
* Hypersensitivity to latex.
* 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.
* Pregnant or lactating female.
* Female planning to become pregnant or planning to discontinue contraceptive precautions before 2 months after the last dose of study vaccine.
* Any condition which, in the opinion of the investigator, prevents the subject from participating in the study.

Exclusion Criteria:

* Receipt of immunoglobulins and/or any blood products within the 90 days preceding the first dose of study vaccine or planned administration during the study period.
* Administration or planned administration of any other immunizations within 30 days before the first or second study vaccination or scheduled within 30 days after study vaccination.
