入选标准

  • Japanese male or female infants ≥2 months to ≤6 months at the time of consent.
  • Healthy infants determined by clinical assessment, including medical history and clinical judgment, to be eligible for the study.

排除标准

  • History of severe adverse reaction associated with a vaccine and/or severe allergic reaction (eg, anaphylaxis)
  • Major known congenital malformation or serious chronic disorder.
  • History of microbiologically proven invasive disease caused by S pneumoniae.
  • Other acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the participant inappropriate for entry into this study.

结局指标

主要结局

Percentage of Participants With Serious Adverse Events (SAEs) From Dose 1 to 1 Month After Dose 4

时间窗: From Dose 1 to 1 Month after Dose 4

A serious AE was any untoward medical occurrence that, at any dose: resulted in death; required inpatient hospitalization or prolongation of existing hospitalization; was life-threatening; resulted in persistent or significant disability/ incapacity; congenital anomaly/birth defect and other important medical events.

Percentage of Participants With Newly Diagnosed Chronic Medical Conditions (NDCMCs) From Dose 1 to 1 Month After Dose 4

时间窗: From Dose 1 to 1 Month after Dose 4

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

Percentage of Participants With Local Reactions Within 7 Days After Dose 3

时间窗: Within 7 Days after Dose 3

Local reactions included pain at injection site, redness and swelling were measured and recorded in measuring device (caliper) units. 1 measuring device unit =0.5 cm. Pain at injection site was graded as mild: hurts if gently touched; moderate: hurts if gently touched with crying; severe: limited limb movement. Redness and swelling were graded as mild: \>0 to 2.0 cm; moderate \>2.0 to 7.0 cm; and severe: \>7.0 cm.
