简要总结
This study will compare the immune responses of the infants who have been given 13vPnC in the mutidose vial formulation to the immune reponses of the infants who have been given 13vPnC in the single-dose syringe formulation.
It will also evaluate the safety of 13-valent pneumococcal conjugate vaccine (13vPnC) in all infants who are vaccinated.

结局指标
主要结局
Number of Participants Reporting Local Reaction Within 5 Days After Dose 2 in MDV and SDS Group
时间窗: Within 5 days after Dose 2 (Day 2 to Day 6) of the infant series
Local reactions were reported within 5 days (day 2 to day 6) using an electronic diary. Tenderness was scaled as Any (tenderness present); Mild (hurt if gently touched; Moderate (hurt if gently touched with crying); Severe (caused limitation of limb movement). Redness and swelling were scaled as Any (redness or swelling present); Mild (0.5 centimeters \[cm\] to 2.0 cm); Moderate (2.1 to 7.0 cm); Severe (greater than \[\>\] 7.0 cm). Participants may be represented in more than 1 category.

Tenderness was scaled as Any (tenderness present); Mild (hurt if gently touched; Moderate (hurt if gently touched with crying); Severe (caused limitation of limb movement). Redness and swelling were scaled as Any (redness or swelling present); Mild (0.5 centimeters \[cm\] to 2.0 cm); Moderate (2.1 to 7.0 cm); Severe (greater than \[\>\] 7.0 cm). Participants may be represented in more than 1 category.
Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) in the Infant Series
时间窗: Dose 1 up to 28 to 42 days after dose 3
An AE was any untoward medical occurrence in a participants who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to 28 to 42 days after last dose that were absent before treatment or that worsened relative to pretreatment state
Percentage of Participants Achieving a Serotype-Specific Pneumococcal Immunoglobulin G (IgG) Antibody Concentration Greater Than or Equal To (>=) 0.35 Microgram Per Milliliter (mcg/mL) 1 Month After the Infant Series for Each Vaccine Group
时间窗: 1 month after the infant series
Percentage of participants achieving predefined antibody threshold \>=0.35 mcg/mL along with the corresponding 95% confidence interval (CI) for the 13 pneumococcal serotypes (serotypes 1, 3, 4, 5, 6A, 6B, 7F 9V, 14, 18C, 19A, 19F and 23F) are presented. Exact 2-sided confidence interval (Clopper and Pearson) based on the observed proportion of participants. Here "n"= participants with valid and determinate IgG concentration to the given serotype.
Number of Participants Reporting Local Reaction Within 5 Days After Dose 1 in MDV and SDS Group
时间窗: Within 5 days after Dose 1(Day 2 to Day 6) of the infant series
Local reactions were reported within 5 days (day 2 to day 6) using an electronic diary. Tenderness was scaled as Any (tenderness present); Mild (hurt if gently touched; Moderate (hurt if gently touched with crying); Severe (caused limitation of limb movement). Redness and swelling were scaled as Any (redness or swelling present); Mild (0.5 centimeters \[cm\] to 2.0 cm); Moderate (2.1 to 7.0 cm); Severe (greater than \[\>\] 7.0 cm). Participants may be represented in more than 1 category.
Geometric Mean Concentration (GMC) for Serotype-Specific Pneumococcal Immunoglobulin G (IgG) Antibody 1 Month After the Infant Series for Each Vaccine Group
时间窗: 1 month after the infant series
Antibody GMC for the 13 pneumococcal serotypes (serotypes 1, 3, 4, 5, 6A, 6B, 7F 9V, 14, 18C, 19A, 19F and 23F) are presented. GMC (13vPnC) and corresponding 2-sided 95% CI were evaluated. Geometric means (GMs) were calculated using all participants with available data for the specified blood draw. CIs were back transformations of a confidence interval based on the Student t distribution for the mean logarithm of the concentrations. Here "n"= participants with valid and determinate IgG concentration to the given serotype.
Number of Participants Reporting Systemic Events Within 5 Days After Dose 1 in MDV and SDS Group
时间窗: Within 5 days after Dose 1 (Day 2 to Day 6) of infant series
Systemic events (any fever greater than or equal to \[\>=\] 38.0 degrees Celsius \[C\], decreased appetite was scaled as; Moderate (decreased oral intake); Severe (refusal to feed). Irritability scaled as; Mild (easily consolable); Moderate (requiring increased attention); Severe (Inconsolable, crying that cannot be comforted). Increased sleep was scale as; mild (increased or prolonged sleeping bouts); Moderate (slightly subdued interfering with daily activity); Severe (Disabling not interested in usual daily activity) and use of antipyretic medication were reported using an electronic diary. Participants may be represented in more than 1 category.
Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs) Prior to Dose 1
时间窗: Informed consent up to Dose 1
An AE was any untoward medical occurrence in a participants who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Adverse events were also reported in participants who provided consent but were not randomized in this study. The data of these participants has been reported under 'Screened Only' arm.
