Brief 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 Malian subjects previously enrolled in the primary vaccination study NCT00678301. This protocol posting deals with objectives & outcome measures of the booster phase. The objectives & outcome measures of the primary phase are presented in a separate protocol posting (NCT number = NCT00678301).

Inclusion criteria

* Subjects who the investigator believes that their parent(s)/Legally Acceptable 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 (drug or vaccine) 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 (pharmaceutical product or device). * 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.

Number of Subjects With Any, Grade 3 and Related Solicited General SymptomsWithin 4 days (Day 0-Day 3) after the booster doseAssessed solicited general symptoms were drowsiness, fatigue, fever \[defined as axillary temperature equal to or above 37.5 degrees Celsius (°C)\], irritability and loss of appetite. Any = occurrence of the symptom regardless of intensity grade. Grade 3 Drowsiness and Irritability = symptom that prevented normal activity. Grade 3 Loss of appetite = not eating at all. Grade 3 fever = fever \> 39.5 °C. Related = symptom assessed by the investigator as related to the vaccination.

Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade. Grade 3 pain = pain that prevented normal activity. Grade 3 redness/swelling = redness/swelling spreading beyond 30 millimeters (mm) of injection site.

Time frame: Within 4 days (Day 0-Day 3) after the booster dose

Population: The analysis was performed on the Total Vaccinated cohort, which included all subjects with at least one vaccine dose administration documented.

Number of Subjects With Any, Grade 3 and Related Solicited General Symptoms

Assessed solicited general symptoms were drowsiness, fatigue, fever \[defined as axillary temperature equal to or above 37.5 degrees Celsius (°C)\], irritability and loss of appetite. Any = occurrence of the symptom regardless of intensity grade. Grade 3 Drowsiness and Irritability = symptom that prevented normal activity. Grade 3 Loss of appetite = not eating at all. Grade 3 fever = fever \> 39.5 °C. Related = symptom assessed by the investigator as related to the vaccination.

Time frame: Within 4 days (Day 0-Day 3) after each vaccine dose

Population: The analysis was performed on the Total Vaccinated cohort, which included all subjects with at least one vaccine dose administration documented.

Number of Subjects With Any Unsolicited Adverse Events (AEs)

An unsolicited AE covers any untoward medical occurrence in a clinical investigation subject temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product and reported in addition to those solicited during the clinical study and any solicited symptom with onset outside the specified period of follow-up for solicited symptoms. Any was defined as the occurrence of any unsolicited AE regardless of intensity grade or relation to vaccination.

Time frame: Within 31 days (Day 0-Day 30) after each vaccine dose

Population: The analysis was performed on the Total Vaccinated cohort, which included all subjects with at least one vaccine dose administration documented.

Opsonophagocytic Activity Against Cross-reactive Pneumococcal Serotypes 6A and 19A

OPA titers against pneumococcal serotypes 6A and 19A (Opsono-6A and Opsono-19A) were calculated, expressed as geometric mean titers (GMTs) and tabulated. The seropositivity cut-off for the assay was ≥ 8.

Time frame: Prior to (PRE) and one month after (POST) the booster immunization in the Synflorix Primed Group and prior to (PRE) the first dose and one month after (POST) the second dose of the catch-up vaccination in the Synflorix Unprimed Group

Population: The analysis was performed on the ATP cohort for immunogenicity, which included all evaluable subjects (i.e. those meeting all eligibility criteria, complying with the procedures and intervals defined in the protocol, with no elimination criteria during the study) for whom immunogenicity data were available.
