Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* 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.

Exclusion Criteria

* 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.
