- Subjects who the investigator believes will comply with the requirements of the protocol should be enrolled in the study.
- A male or female between, and including, 18 and 40 years of age at the time of the first vaccination.
- Pneumonia within 3 years prior to 1st vaccination.
- Invasive Pneumococcal Disease within 3 years prior to 1st vaccination.
- Subjects who the investigator believes will comply with the requirements of the protocol should be enrolled in the study.
- A male or female between, and including, 18 and 40 years of age at the time of the first vaccination.
- Written informed consent obtained from the subject.
- Subject without medical history, clinical finding or laboratory finding, which, in the opinion of the investigator, could pose a safety concern or interfere with the protocol.
- If the subject is female, and of childbearing potential, she agrees to use adequate contraception and not become pregnant for the duration of the study.
- Pneumonia within 3 years prior to 1st vaccination.
- Invasive Pneumococcal Disease within 3 years prior to 1st vaccination.
- Use of any investigational or non-registered product other than the study vaccine(s) within 30 days preceding the first dose of study vaccine, or planned use during the study period or participation to another pharmaceutical/vaccine study.
- Chronic administration of immunosuppressants or other immune-modifying drugs within six months prior to the first vaccine dose.
- Planned administration/administration of a vaccine not foreseen by the study protocol within 30 days of the first dose of vaccines, with the exception of the influenza vaccine which can be administered >14 days prior to or >14 days following vaccine doses 1 and 2.
- 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, including human immunodeficiency virus infection.
- History of reaction or hypersensitivity to any component of the vaccine.
- Any serious, uncontrolled disease likely to interfere with the study as determined by history, physical examination or laboratory screening, as per the judgment of the Investigator.
- Inflammatory processes such as known chronic infections.
- All past or current malignancies and lymphoproliferative disorders.
- Laboratory evidence of haematological and biochemical abnormalities.
- Acute disease at the time of enrolment/vaccination.
- Pregnant or lactating female.
- Female planning to become pregnant or planning to discontinue contraceptive precautions.
- History of chronic alcohol consumption and/or drug abuse.
- Other conditions that the principal investigator judges may interfere with study findings.
