Local reactions were recorded using an electronic diary (e-diary). Local reactions included redness, swelling and pain at the injection site. Redness and swelling were measured and recorded in measuring device units. 1 measuring device unit =0.5 centimeter (cm). Redness and swelling were graded as mild (greater than \[\>\] 2.0 to 5.0 cm), moderate (\>5.0 to 10.0 cm) and severe (\>10.0 cm). Pain at injection site was graded as mild (did not interfere with activity), moderate (interfered with activity), and severe (prevented daily activity).

Systemic events fever, fatigue, headache, muscle pain and joint pain were recorded by using an e-diary. Fever was defined as temperature \>=38.0 degree Celsius (C) and categorized to \>=38.0 to 38.4 degree C, \>38.4 to 38.9 degree C, \>38.9 to 40.0 degree C and \>40.0 degree C. Fatigue, headache, muscle pain and joint pain were graded as mild (did not interfere with activity), moderate (some interference with activity) and severe (prevented daily routine activity).

An AE was any untoward medical occurrence in study participants who received study vaccine without regard to possibility of causal relationship with the treatment.

An SAE was any untoward medical occurrence at any dose that results in death; is life-threatening (immediate risk of death); requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity (substantial disruption of the ability to conduct normal life functions); results in congenital anomaly/birth defect or that is considered to be an important medical event.

An NDCMC was defined as a disease or medical condition, not previously identified, that was expected to be persistent or was otherwise long-lasting in its effects.

OPA GMTs were determined for serotypes: 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, 23F, 8, 10A, 11A, 12F, 15B, 22F and 33F. OPA titer was expressed as reciprocal of the highest serum dilution.

GMFR for the 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) from before 13vPnC Dose 1 to 1 month after 13vPnC Dose 3 were computed using the logarithmically transformed assay results. Confidence interval (CI) for GMFR were back transformations of a CI based on the Student t distribution for the mean logarithm of the mean fold rise. GMFRs were calculated using all participants with available data from both before 13vPnC Dose 1 and after 13vPnC Dose 3 blood draws.

Antibody geometric mean concentration (GMC) as measured by micrograms per milliliter (mcg/mL) for 7 common pneumococcal serotypes (serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F) and 6 additional pneumococcal serotypes specific to 13vPnC (Serotypes 1, 3, 5, 6A, 7F, and 19A) were presented. GMC (13vPnC) and corresponding 2-sided 95% confidence intervals (CI) were evaluated. GMCs were calculated using all participants with available data for the specified blood draw.

Serotype-specific antibody-mediated opsonophagocytic activity (functional antibodies) for the 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) as measured by a quantitative opsonophagocytic activity assay (OPA). OPA titers will be logarithmically transformed for analysis; geometric means calculated and expressed as geometric mean titers (GMTs). The 2-sided, 95% confidence intervals (CIs) on the GMTs were constructed by back transformation of the CIs for the mean of the logarithmically transformed assay results computed using the Student t distribution.

Serotype-specific antibody-mediated opsonophagocytic activity (functional antibodies) for the 13 pneumococcal serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) as measured by a quantitative opsonophagocytic activity assay (OPA). OPA titers will be logarithmically transformed for analysis; geometric means calculated and expressed as geometric mean titers (GMTs). The 2-sided, 95% CIs on the GMTs were constructed by back transformation of the CIs for the mean of the logarithmically transformed assay results computed using the Student t distribution.

Geometric mean fold rises (GMFRs) for the 13 serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) from prevaccination to 1 month postvaccination were computed using the logarithmically transformed assay results. CI for the GMFRs are back transformations of a CI based on the Student t distribution for the logarithmically transformed assay results.

Geometric mean fold rises (GMFRs) for the 13 serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F) from prevaccination to 1 month postvaccination were computed using the logarithmically transformed assay results. CI for the GMFRs are back transformations of a CI based on the Student t distribution for the logarithmically transformed assay results.

Percentages of participants achieving World Health Organization (WHO) predefined antibody threshold ≥ 0.35 μg/mL along with the corresponding 95% CI for the 7 common pneumococcal serotypes (serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F) and 6 additional pneumococcal serotypes specific to 13vPnC (serotypes 1, 3, 5, 6A, 7F, and 19A) are presented.

Local reactions included redness, swelling and pain at the injection site collected in an electronic diary (e-diary) or case report form(CRF). Redness and swelling were measured and recorded in measuring device units. One measuring device unit=0.5 centimeter (cm). Redness and swelling reported in e-diary were graded as mild: greater than (\>) 2.0 cm to 5.0 cm, moderate: \>5.0 cm to 10.0 cm and severe \> 10 cm. Pain at injection site was graded as mild: did not interfere with activity; moderate: interfered with activity; and severe: prevented daily activity. Severity definition from CRF: mild (does not interfere)/moderate (interferes to some extent)/severe(interferes significantly) with the participant's usual function. Exact 2-sided 95% confidence interval (CI) was based on the Clopper and Pearson method.

Systemic events included fever, fatigue, headache, muscle pain and joint pain and were collected in an e-diary or CRF. Fever was defined as temperature greater than or equal to (\>=) 38.0 degrees Celsius (C) and categorized as \>=38.0 to 38.4 degrees C, \>38.4 to 38.9 degrees C, \>38.9 to 40.0 degrees C and \>40.0 degrees C. Fatigue, headache, muscle pain and joint pain were graded as mild: did not interfere with activity; moderate: some interference with activity and severe: prevented daily routine activities.

An AE was defined as any untoward medical occurrence in a participant temporally associated with the use of study intervention, whether or not considered related to the study intervention. Exact 2-sided 95% CI was based on the Clopper and Pearson method.

An SAE was defined as any untoward medical occurrence that, at any dose, met one or more of the following criteria - resulted in death, was life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect and was a suspected transmission via a Pfizer product of an infectious agent, pathogenic or non-pathogenic and other important medical event. Exact 2-sided 95% CI was based on the Clopper and Pearson method.
