What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants With a Solicited Injection-site Adverse Event (AE)	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.	Day 1 to Day 14 post each vaccination
Percentage of Participants With a Solicited Systemic Adverse Event	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).	Day 1 to Day 14 post each vaccination
Percentage of Participants With a Vaccine-related Serious Adverse Event (SAE)	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.	Up to 4 weeks post vaccination 4 (~14.5 months)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Percentage of Participants Meeting the Serotype-specific Immunoglobulin G (IgG) Threshold of ≥0.35 µg/mL	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.	One month post vaccination 3 (~3 months after Vaccination 1)
Serotype-specific IgG Geometric Mean Concentrations (GMCs)	The anti-pneumococcal polysaccharide (PnPs) serotype-specific IgG Geometric Mean Concentrations (GMCs) were determined using an electrochemiluminescence assay.	1 month post vaccination 3 (~3 months after Vaccination 1)
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)	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.	1 month post vaccination 3 (~3 months after Vaccination 1)
