• 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.
• Fever at the time of vaccination. Fever is defined as temperature >= 37.5°C on oral setting.
• Physical examination positive for acrocyanosis, jaundice, splenomegaly.
• Acute or chronic, clinically significant anaemia, pulmonary, cardiovascular, hematologic, hepatic or renal functional abnormality, as determined by physical examination or laboratory screening tests, at the discretion of the investigator
• Administration of immunoglobulins and/or any blood products within the three months preceding vaccination or planned administration during the study period.
• Pregnant or lactating female.
• Female planning to become pregnant or planning to discontinue contraceptive precautions.
• History of chronic alcohol consumption and/or drug abuse.
• Other conditions that the principal investigator judges may interfere with study findings.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Subjects With Grade 3 Solicited Local Symptoms	Assessed solicited local symptoms were pain, redness and swelling. Grade 3 pain = significant pain at rest, pain that prevented normal activity. Grade 3 redness/swelling = redness/swelling spreading beyond 50 millimeters (mm) of injection site.	During the 7-day (Days 0-6) post-booster vaccination period
Number of Subjects With Grade 3 and Vaccine-related Solicited General Symptoms	Assessed solicited general symptoms were fatigue, gastrointestinal symptoms (nausea, vomiting, diarrhoea and/or abdominal pain), headache, malaise, myalgia and fever [defined as oral temperature equal to or above (≥) 37.5 degrees Celsius (°C)]. Grade 3 symptom = symptom that prevented normal activity. Grade 3 fever = fever > 39.5 °C. Related = general symptom assessed by the investigator to be casually related to the study vaccination.	During the 7-day (Days 0-6) post-booster vaccination period
Number of Subjects With Grade 3 and Vaccine-related 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. Grade 3 AE = an AE which prevented normal, everyday activities. Related = AE assessed by the investigator as related to the vaccination.	During the 31-day (Days 0-30) post-booster vaccination period
Number of Subjects With Any Vaccine-related Serious Adverse Events (SAEs)	SAEs assessed include medical occurrences that result in death, are life-threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity.	During the entire study period (from Day 0 to Day 30)
Number of Subjects With Grade 3 Haematological or Biochemical Abnormalities	Among haematological or biochemical abnormalities assessed were: Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), Cholesterol, Creatine Phosphokinase (CRP), Hemoglobin decrease, Haemoglobin, Lactate dehydrogenase (LDH), Neutrophils, Red blood cells (RBC), Reticulocytes, White blood cells (WBC) and Overall parameters. Assessment of intensity: Grading of the haematological and biochemical parameters was performed using the standard Food and Drug Administration (FDA) Toxicity Grading Scale. Changes compared to normal reference ranges were graded: Grade 1 = Mild; Grade 2 = Moderate; Grade 3 = Severe; Grade 4 = Potentially Life Threatening	At Days 1 and 6 post-booster vaccination

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Antibody Concentrations Against Pneumococcal Pneumolysin Toxoid (dPly) and Histidine Triad Protein D (PhtD) Proteins	Anti-dPly and anti-PhtD antibody concentrations are presented as geometric mean concentrations (GMCs), expressed in LU/mL. The reference seropositivity cut-off values were equal to or above (≥) 599 LU/mL for anti-dPly and ≥ 391 LU/mL for anti-PhtD.	Prior to the booster vaccination (Day 0) and one month post-booster vaccination (Day 30)
Titers for Antibodies Against Pneumolysin Haemolysis (Hem-dPly) Protein	Antibody titers are presented as geometric mean titers (GMTs). The reference seropositivity cut-off value was equal to or above (≥) 6.	Prior to the booster vaccination (Day 0) and one month post-booster vaccination (Day 30)
Number of Subjects With Any Solicited Local Symptoms	Assessed solicited local symptoms were pain, redness and swelling. Any = occurrence of the symptom regardless of intensity grade.	During the 7-day (Days 0-6) post-booster vaccination period
Number of Subjects With Any Solicited General Symptoms	Assessed solicited general symptoms were fatigue, gastrointestinal symptoms (nausea, vomiting, diarrhoea and/or abdominal pain), headache, malaise, myalgia and fever [defined as oral temperature equal to or above (≥) 37.5 degrees Celsius (°C)]. Any = occurrence of the symptom regardless of intensity grade.	During the 7-day (Days 0-6) post-booster vaccination period
Number of Subjects With Any Unsolicited 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.	During the 31-day (Days 0-30) post-booster vaccination period
Number of Subjects With Any SAEs	SAEs assessed include medical occurrences that result in death, are life-threatening, require hospitalization or prolongation of hospitalization or result in disability/incapacity.	During the entire study period (from Day 0 to Day 30)
Number of Subjects With Grade 1, Grade 2 and Grade 4 Haematological or Biochemical Abnormalities	Among haematological or biochemical abnormalities assessed were: Alanine aminotransferase (ALT), Aspartate aminotransferase (AST), Cholesterol, Creatine Phosphokinase (CRP), Hemoglobin decrease, Haemoglobin, Lactate dehydrogenase (LDH), Neutrophils, Red blood cells (RBC), Reticulocytes, White blood cells (WBC) and Overall parameters. Assessment of intensity: Grading of the haematological and biochemical parameters was performed using the standard Food and Drug Administration (FDA) Toxicity Grading Scale. Changes compared to normal reference ranges were graded: Grade 1 = Mild; Grade 2 = Moderate; Grade 3 = Severe; Grade 4 = Potentially Life Threatening	At 1 and 6 days post-booster vaccination
