Primary Outcome Measures

Name	Time	Method
Percentage of Participants With a Solicited Systemic Adverse Event	Day 1 to Day 14 post each vaccination	An AE is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. Solicited systemic AEs were decreased appetite (appetite loss), somnolence (drowsiness), irritability and urticaria (hives/welts).
Percentage of Participants With a Solicited Injection-site Adverse Event (AE)	Day 1 to Day 14 post each vaccination	An AE is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. Solicited injection-site AEs were injection site erythema (redness), injection site induration (hard lump), injection site pain and injection site swelling.
Percentage of Participants With a Vaccine-related Serious Adverse Event (SAE)	Up to 4 weeks post vaccination 4 (~14.5 months)	An SAE is an AE that is life-threatening, requires or prolongs an existing hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly or birth defect, or is another important medical event deemed such by medical or scientific judgment. Relatedness of an SAE to the study vaccine was determined by the investigator.

Secondary Outcome Measures

Name	Time	Method
Percentage of Participants Meeting the Serotype-specific Immunoglobulin G (IgG) Threshold of ≥0.35 µg/mL	One month post vaccination 3 (~3 months after Vaccination 1)	Serotype-specific pneumococcal IgG antibody was measured using pneumococcal electrochemiluminescence (PnECL). The percentage of participants with serotype-specific IgG ≥0.35 µg/mL was summarized for each serotype.
Serotype-specific IgG Geometric Mean Concentrations (GMCs)	1 month post vaccination 3 (~3 months after Vaccination 1)	The anti-pneumococcal polysaccharide (PnPs) serotype-specific IgG Geometric Mean Concentrations (GMCs) were determined using an electrochemiluminescence assay.
Percentage of Participants Meeting Threshold Values for Protective Responses to DTaP-IPV (Diphtheria Toxin, Tetanus Toxin, Pertussis Toxin, Pertussis Filamentous Hemagglutinin (FHA) and Polio Virus Type 1/2/3)	1 month post vaccination 3 (~3 months after Vaccination 1)	DTaP-IPV antibody titers were measured by neutralization assay (diphtheria toxin and poliovirus 1/2/3), particle agglutination assay (tetanus toxin) and enzyme-linked immunosorbent assay (ELISA) methodology (pertussis PT and pertussis FHA) 1 month post vaccination 3. Threshold values were: Diphtheria toxin level ≥0.1 IU/mL, Pertussis PT level ≥10 EU/mL, Pertussis FHA level ≥10 EU/mL, Tetanus toxin level ≥0.01 IU/mL, Neutralizing antibody (NA) titers of Polio virus types 1/2/3 ≥1:8.
