        Exclusion Criteria:

        Medical conditions

             unsafe.

          -  Any confirmed or suspected immunosuppressive or immunodeficient condition, based on
             medical history and physical examination (no laboratory testing required).

          -  History of any reaction or hypersensitivity likely to be exacerbated by any component
             of the vaccine.

          -  Hypersensitivity to latex.

          -  Serious or unstable chronic illness. Patients with chronic stable conditions with or
             without specific treatment, such as diabetes, hypertension or cardiac disease, are
             allowed to participate in this study.

          -  Any other condition that, in the opinion of the investigator, might interfere with the
             evaluations required by the study.

          -  History of any neurological disorders or seizures.

          -  Acute or chronic, clinically significant pulmonary, cardiovascular, hepatic or renal
             functional abnormality, as determined by the investigator based on medical history,
             physical examination or laboratory screening tests.

          -  Hepatomegaly, right upper quadrant abdominal pain or tenderness.

          -  Significant underlying illness that in the opinion of the investigator would be
             expected to prevent completion of the study.

          -  Lymphoproliferative disorder and malignancy within 5 years.

          -  At screening: Hematology parameters (complete blood cell count [red blood cells, WBC],

             platelets count or hemoglobin level) and/or biochemistry parameters (creatinine, blood
             urea nitrogen or liver enzymes [ALT or AST]) outside the normal laboratory ranges,
             unless the laboratory abnormalities are considered not clinically significant by the

             influenza vaccines which can be administered up to 14 days before or from 30 days
             after each study vaccination.

          -  Previous vaccination with an RSV vaccine.

          -  Known previous administration of a vaccine containing MPL, QS-21 and/or MF59.

          -  Planned administration of GSK's Herpes Zoster vaccine marketed as Shingrix or an

             immunosuppressants or other immune-modifying drugs during the period starting 6 months
             prior to the first vaccine dose. For corticosteroids, this will mean prednisone (≥ 20
             mg/day, or equivalent). Inhaled and topical steroids are allowed.

             time during the study period.

        Other exclusions

          -  History of chronic alcohol consumption and/or drug abuse as deemed by the investigator
