Outcomes
Primary Outcome Measures
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.
Secondary Outcome Measures
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.
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.
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.
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.
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.
Number of Subjects With Serious Adverse Events (SAEs)
Serious adverse events (SAEs) assessed include medical occurrences that result in death, are life-threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity.
Concentrations of Antibodies Against Vaccine Pneumococcal 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.

Concentrations of Antibodies Against Cross-reactive Pneumococcal Serotypes 6A and 19A
Cross-reactive pneumococcal serotypes assessed were serotypes 6A and 19A. 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.
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.
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).
