Summary
The purpose of this trial is to assess the safety, reactogenicity and immunogenicity of GSK
Biologicals' pneumococcal conjugate vaccine GSK1024850A when administered either as a
booster dose or as a two dose catch-up vaccination in the second year of life to the

Eligibility
Minimum age: 15 Months.
Maximum age: 21 Months.

Representative(s) (LAR(s)) can and will comply with the requirements of the protocol.
- A male or female, between and including 15-21 months of age at the time of visit 1.
- For the Pn-Pn group, subjects who completed the full vaccination course in study
NCT00678301. For the Zil-Pn group, subjects who were previously enrolled in the
control group of study NCT00678301.
- Written informed consent, signed or thumb printed, obtained from the parent(s)/LAR(s)
of the subject. Where parent(s)/LAR(s) are illiterate, the consent form will be
countersigned by a witness.
- Healthy subjects as established by medical history and clinical examination before
entering into the study.
Exclusion Criteria:
- Use of any investigational or non-registered product other than the study
vaccine(s)/product(s) within 30 days preceding the first dose of vaccine, or planned
use during the study period.
- Chronic administration of immunosuppressants or other immune-modifying drugs within
six months prior to vaccination.
- Planned administration/administration of a vaccine not foreseen by the study protocol
during the period starting from 30 days before each dose of study vaccine and ending
30 days after. Locally recommended vaccines for example Oral Polio Vaccine or
influenza vaccine are always allowed, even if concomitantly administered with the
study vaccines, but should be documented in the CRF.
- 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 product.
- Administration of any pneumococcal vaccine since the end of study NCT00678301.
- Any confirmed or suspected immunosuppressive or immunodeficient condition, since the
end of study NCT00678301, based on medical history and physical examination.
- Major congenital defects or serious chronic illness.
- History of any progressive neurological disorders or seizures.
- Acute disease and/or fever at the time of enrolment.
- History of any reaction or hypersensitivity likely to be exacerbated by any component
of the vaccines.
- Administration of immunoglobulins and/or any blood products less than 3 months prior
to visit 1 or planned use during the study.
- Child in care.
