For corticosteroids, this will mean prednisone ≥20 mg/day, or equivalent. Only topical steroids are allowed.~* Administration of long-acting immune-modifying drugs at any time during the study period.~* 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.~* Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination.~* History of or current autoimmune disease.~* Acute disease and/or fever at the time of enrolment.~  * Fever is defined as temperature \>= 37.5°C for oral or axillary 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.~* Current alcoholism and/or drug abuse.~* History of or current condition preventing intramuscular injection as bleeding or coagulation disorder.~* Malignancies within previous 5 years or lymphoproliferative disorders.~* Pregnant or lactating female.~* Female planning to become pregnant or planning to discontinue contraceptive precautions.~* Any other condition that the investigator judges may interfere with study findings.~only applicable for Step 1~* Planned administration/ administration of a vaccine not foreseen by the study protocol in the period starting 30 days before the first dose and ending 30 days after the last dose of vaccine, with the exception of any influenza vaccine which may be administered ≥ 15 days preceding or following any study vaccine dose.~* Laboratory evidence of clinically significant haematological (complete blood cell count \[RBC, WBC\], WBC differential count \[lymphocytes, neutrophils and eosinophils\], platelets count or haemoglobin level) and biochemical (alanine aminotransferase \[ALT\], aspartate aminotransferase \[AST\] or creatinine) abnormalities as per the opinion of the investigator.~only applicable for Step 2~* Planned administration/ administration of a vaccine not foreseen by the study protocol in the period starting 30 days before the first dose and ending 30 days after the last dose of vaccine, with the exception of any influenza or pneumococcal licensed vaccine which may be admin-istered ≥ 15 days preceding or following any study vaccine dose.~* Post-bronchodilator FEV1 \< 80% of predicted normal value.~* Diagnosed with a respiratory disorder (e.g. asthma, COPD, sarcoidosis, tuberculosis, bronchiectasis, lung fi-brosis, pulmonary embolism, pneumothorax, or physi-cian confirmed lung cancer). Please note that subjects with mild pulmonary obstruction (i.e. FEV1/ FVC ratio \< 0.7 with FEV1 ≥ 80% of normal predicted values \[GOLD grade 1\]) can be enrolled.~* Has contraindication for spirometry testing (such as recent eye surgery, recent thoracic or abdominal surgery procedures, unstable cardiovascular status, recent myo-cardial infection or pulmonary embolism).~* Laboratory evidence of clinically significant haematological (complete blood cell count \[RBC, WBC\], WBC differential count \[lymphocytes, neutrophils and eosinophils\], platelets count or haemoglobin level) and biochemical (ALT, AST or creatinine) abnormalities.~* Has significant disease, in the opinion of the investigator, likely to interfere with the study and/or likely to cause death within the study duration.

Study Arms:
- GSK3277513A F1 Group (Type: EXPERIMENTAL): Subjects, 18 - 40 years, receiving two doses of the non adjuvanted GSK Biologicals' NTHi Mcat investigational vaccine (GSK3277513A ) containing formulation 1 (F1) of PD, PE-PilA and UspA2 during Step 1 of the study. Intramuscular injection should be done in the deltoid of the non-dominant arm. In case it is not possible to inject in the non dominant arm, an injection in the dominant arm may be performed.
- GSK3277513A F2 Group (Type: EXPERIMENTAL): Subjects, 50 - 70 years, receiving two doses of the GSK Biologicals' NTHi-Mcat investigational vaccine(GSK3277513A) containing formulation 2 (F2) (adjuvanted) of PD, PE-PilA and UspA2 during Step 2 of the study. Intramuscular injection should be done in the deltoid of the non-dominant arm. In case it is not possible to inject in the non dominant arm, an injection in the dominant arm may be performed.
- GSK3277513A F3 Group (Type: EXPERIMENTAL): Subjects, 50 - 70 years, receiving two doses of the GSK Biologicals' NTHi-Mcat investigational vaccine(GSK3277513A) containing formulation 3 (F3) (adjuvanted) of PD, PE-PilA and UspA2 during Step 2 of the study. Intramuscular injection should be done in the deltoid of the non-dominant arm. In case it is not possible to inject in the non dominant arm, an injection in the dominant arm may be performed.
- Placebo Group (Type: PLACEBO_COMPARATOR): Subjects, 18 - 40 years, receiving two doses of placebo (saline solution) during Step 1 of the study and subjects, 50 - 70 years, receiving two doses of placebo (saline solution) during Step 2 of the study. Intramuscular injection should be done in the deltoid of the non-dominant arm. In case it is not possible to inject in the non dominant arm, an injection in the dominant arm may be performed.
