•Written informed consent obtained from the subject.
•Free of obvious health problems as established by medical history, clinical examination and clinical laboratory assessment before entering into the study.
•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

Exclusion Criteria

•Use of any investigational or non-registered product (drug or vaccine) other than the study vaccines within 30 days preceding the vaccination, or planned use during the study period.
•Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs within six months prior to vaccination. (For corticosteroids, this will mean prednisone = 10 mg/day, or equivalent. Inhaled and topical steroids are allowed.)
•Planned administration/administration of a vaccine not foreseen by the study protocol during the period starting 30 days prior to the vaccination and ending one month (minimum 30 days) after vaccination.
•Administration of any pneumococcal vaccine other than the study vaccine during the period between end of study SPNG-001 and study vaccination.
•Bacterial pneumonia within the period between end of study SPNG-001 and study vaccination.
•Invasive pneumococcal disease (IPD) within the period between end of study SPNG-001 and study vaccination.
•Any confirmed or suspected immunosuppressive or immunodeficient condition, including human immunodeficiency virus (HIV) infection (no laboratory testing required).
•History of thrombocytopenia or bleeding disorder.
•Anaphylactic reaction following the previous administration of the vaccine or history of reactions or allergic disease likely to be exacerbated by any component of the vaccine.
•Current serious neurologic or mental disorders.
•Inflammatory processes such as known chronic active infections (e.g. Hepatitis B, C).
•All past or current malignancies (excluding non-melanic skin cancer) and lymphoproliferative disorders.
•Acute disease at the time of enrolment/vaccination.
Acute disease is defined as the presence of a moderate or severe illness with or without fever). All vaccines can be administered to persons with a minor illness such as diarrhea, mild upper respiratory infection without fever.

•Fever at the time of vaccination.
Fever is defined as temperature = 37.5°C on oral setting.

- Type 2 diabetes
- Uncontrolled hypertension
- Current or history of coronary artery disease or cardiac insufficiency
- Current or history of rheumatoid arthritis or temporal arthritis
