The official eligibility criteria

Registry text, reproduced exactly. These are the words the trial's sponsor published on ClinicalTrials.gov. They have not been edited, shortened or rewritten, and they are written for researchers rather than for patients.

Inclusion Criteria:

* Infants who are about 2 months of age

* 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.

* 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.

* Previous vaccination with any licensed or investigational pneumococcal vaccine, or planned receipt through study participation.

Voxsanity reformats data from public registries into this layout. It does not edit, interpret or add to what the registry published.

Not medical advice.

Individual trial records are refreshed on a rolling basis rather than all at once, so a record may be up to several weeks old. Each trial page and trial card shows the date its own record was last synced. Where a record has lagged, its status, sites and enrolment can differ from the current registry state in either direction, so check the registry link on the trial page before acting on them.
