What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Subjects With Grade 3 Adverse Events (Solicited and Unsolicited)	The incidence and nature of Grade 3 symptoms (solicited and unsolicited), reported during the 31-day (Days 0-30) post-vaccination are presented.	Within 31 days (Day 0-Day 30) after booster vaccination

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Subjects With Any and Grade 3 Solicited Local Symptoms	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.	Within 4 days (Day 0-Day 3) after the booster dose
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.	Within 4 days (Day 0-Day 3) after the booster dose
Number of Subjects With Any and Grade 3 Solicited Local Symptoms	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.	Within 4 days (Day 0-Day 3) after each vaccine dose
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.

Concentrations of Antibodies Against Vaccine Pneumococcal Serotypes 1, 4, 5, 6B, 7F, 9V, 14, 18C, 19F and 23F	Vaccine pneumococcal serotypes assessed were serotypes 1, 4, 5, 6B, 7F, 9V, 14, 18C, 19F and 23F. Concentrations were expressed as geometric mean concentrations (GMCs) in microgram per milliliter (μg/mL). Pneumococcal serotype specific total immunoglobuline G (IgG) antibodies were measured by 22F-inhibition Enzyme-linked immunosorbent assay (ELISA). The cut-off of the assay was ≥ 0.05 μg/mL.	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

Concentrations were expressed as geometric mean concentrations (GMCs) in microgram per milliliter (μg/mL). The antibody concentrations against the cross-reactive pneumococcal serotypes 6A and 19A were determined by 22F-inhibition Enzyme-linked immunosorbent assay (ELISA). The cut-off of the assay was ≥ 0.05 μg/mL.	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
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.	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
Concentrations of Antibodies Against Protein D (PD)	Concentrations of antibodies against protein D (PD) were determined by ELISA assay. Concentrations were expressed as geometric mean concentrations (GMCs) in ELISA units per milliliter (EL.U/mL). Concentration of specific PD antibodies was determined, using a standard reference serum. The cut-off of the assay is ≥ 100 ELISA units per milliliter (EL.U/mL).	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
