How this study is set up

The points below are drawn from the public registry record for this study. Each one cites the field or sentence it came from. A dash (—) means the record does not state something — not that it is missing or wrong. Many well-run studies, especially small ones, leave some of these blank.

  • Registered after enrolment began (about 7 days after the recorded start)First posted 2026-06-05; recorded start 2026-05-29
  • Has a defined primary outcomeA primary outcome measure is listed in the record
  • The primary outcome states a time frameThe primary outcome measure records a time frame
  • Participants are randomly assignedAllocation is recorded as randomised
  • Has a comparison groupThe record lists a placebo or comparator arm, or more than one study arm
  • Uses blinding (masking)A masking level is recorded in the record
  • An ethics committee is not stated in the registry recordThis registry's ingested record has no ethics-committee field
  • Regulatory oversight (such as an IND or IDE) is not stated in the registry recordThis registry's ingested record has no regulatory-authorisation field
  • A data monitoring committee is not stated in the registry recordThis registry's ingested record has no data-monitoring-committee fieldA data monitoring committee is not required for many smaller studies, and its absence here is not unusual.
  • No cost to participants is mentioned in the recordChecked the summary, description and eligibility text; no cost-to-participant phrase found
  • Sponsor has 606 other studies in this databaseCounted from the lead sponsor named in the record (Pfizer)
  • Sponsor has posted results for at least one studyBased on the sponsor’s studies in this database
  • The record lists 1 condition.
  • Lead sponsor type recorded as: industry.
  • Intervention regulatory context: investigational, within a phased regulatory pathway.

These are facts from the public registry record, not a judgement about the study. Discuss any trial with your own doctor before taking part.

Trial stature

Three independent measures of this study, described from its registry record — not a recommendation about it. A rigorous study by investigators nobody has heard of is better evidence than a weak study led by a famous one. How these are scored.

Methodological rigourDEFINITIVE

A definitive-grade design for a phase 3 study, judged from its ClinicalTrials.gov record.

Investigator standingUNKNOWN

We have no verifiable track record for the investigator named on this trial. That is common for early-career investigators and for records held outside ClinicalTrials.gov — it is not a negative signal.

How this score is built
  • Investigator standing0/100

    No investigator recorded in the registry for this trial

These describe the registry record only, and today we hold ClinicalTrials.gov data. Absent fields lower a score, and absence often reflects registration practice rather than study quality. A high-stature trial is not necessarily safer or a better choice for you — enrolling in a large definitive trial can mean a higher chance of receiving placebo, while a small early-phase study may be the only route to a new therapy.

Resumen

The purpose of this study is to learn about the safety of a new pneumococcal vaccine and how the new pneumococcal vaccine helps to fight against germs that can cause pneumonia (lung infections), meningitis (brain infections), and otitis media (ear infections) in infants when compared to the pneumococcal vaccine that is currently in use, 20vPnC (Prevnar 20®). This study will test if the new pneumococcal vaccine is as safe as the one that is currently in use. It will also assess how the new vaccine works in comparison to the one that is currently in use when given with other childhood vaccines. To measure how the new pneumococcal vaccine compares to the current one, blood samples will be used to measure the body's ability to create proteins to fight those germs. This new vaccine can possibly provide additional protection against germs that cause pneumococcal disease that are not included in the vaccines that are currently given to infants. Pneumococcal disease includes a variety of infections caused by a specific germ, Streptococcus pneumoniae. There are three groups in this study. All participants will be assigned to one of the three groups. This study is seeking participants who are: * infants who are 2 months of age in Group 1; * infants who are 2 to 6 months of age in Groups 2 and 3; and * said to be healthy by the study doctor About 3000 infants will be assigned to Group 1. The infants in this group will have a 1 in 2 chance (50%) of receiving either PG4 (new vaccine) or 20vPnC (currently in use) into the left thigh muscle at 2, 4, 6, and 12 to 15 months of age. About 140 infants from outside the United States will be assigned to Group 2. The infants in this group will have a 1 in 2 chance (50%) of receiving either PG4 or 20vPnC into the left thigh muscle at 2 to 6, 3 to 8, 4 to 10, and 12 to 15 months of age. About 90 infants from outside the United States will be assigned to Group 3. The infants in Group 3 will have a 1 in 3 chance (33%) of receiving either PG4 into the left thigh muscle, PG4 under the skin of the left thigh, or 20vPnC into the left thigh muscle at 2 to 6, 3 to 8, 4 to 10, and 12 to 15 months of age. Infants in Group 1 will take part in this study for about 16 to 19 months (about 1 and a half years). Infants in Groups 2 and 3 will take part in this study for 12 to 21 months (about 1 to 1 and a half years). During this time, infants will have 6 study clinic visits and 1 phone call. At these study clinic visits, parent(s)/legal guardian(s) will be asked if the infant experienced any side effects. A side effect is an unintentional or unexpected reaction to a vaccine. Infants will have 3 blood samples collected.

Elegibilidad tal como figura en el registro

Inclusion Criteria: * infants who are 2 months of age in Group 1. * infants who are 2 to 6 months of age in Groups 2 and 3. * 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.
