Summary

This study tests a new pneumococcal vaccine in about 2400 healthy infants starting at 2 months old. The goal is to see if the new vaccine is as safe as the current vaccine, Prevnar 20, and if it can protect against more types of bacteria that cause pneumonia, meningitis, and ear infections. Infants receive four doses over about a year and a half, and researchers track any side effects.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

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.
