• Safety and immune response of three PG4 vaccine lots vs 20vPnC in adults

  This study tests three different lots of a new pneumococcal vaccine and the standard 20vPnC vaccine in adults to see if they are similarly safe and provoke a similar immune response.

  Recruiting at 37 sites Phase 3 Pfizer · Birmingham, Alabama and 36 other locations · NCT07794748

• New pneumococcal vaccine safety and immune response in children and teens

  This study tests whether a new pneumococcal vaccine is as safe and as effective as Prevnar 20 in children and adolescents who have previously received PCV.

  Recruiting at 68 sites Phase 3 Pfizer · Birmingham, Alabama and 76 other locations · NCT07660198

• New pneumococcal vaccine in infants shows safety and how it stacks up against Prevnar 20

  A new pneumococcal vaccine is being tested in healthy infants to see if it is as safe as Prevnar 20 and whether it triggers a similar or better immune response.

  Recruiting at 125 sites Phase 3 Pfizer · Bessemer, Alabama and 129 other locations · NCT07629440

• New pneumococcal vaccine for healthy infants

  A new pneumococcal vaccine is being tested in about 2-month-old healthy babies to see if it is as safe as Prevnar 20 and whether it may offer broader protection against germs that cause pneumonia, meningitis, and ear infections.

  Recruiting at 72 sites Phase 3 Pfizer · Estero, Florida and 90 other locations · NCT07573462

• Serum collection after Gamma-PN vaccination to support assay development

  This project will collect blood samples from people who receive the Gamma-PN vaccine to help develop lab tests for pneumococcal disease.

  Recruiting Phase 1 GPN Vaccines · Adelaide, South Australia · NCT07205289

• How pneumococcal conjugate vaccines may produce antibodies that protect against serogroup 33.

  This will try two different pneumococcal conjugate vaccines in healthy adults to see which one makes antibodies that can kill serogroup 33 bacteria.

  Recruiting Phase 4 University of Alabama at Birmingham · Birmingham, Alabama · NCT07135453

• Pneumococcal Vaccine Test for severely malnourished kids in hospital

  This study tests whether giving Pneumosil to children aged 6–59 months with severe acute malnutrition in hospital elicits a better immune response than a Typhoid vaccine, with follow-up visits over six months.

  Recruiting Phase 4 Menzies School of Health Research · Dili · NCT06817421

• Assessing the effectiveness of a new pneumococcal vaccine in healthy adults

  This study is testing a new pneumococcal vaccine to see if it helps healthy adults aged 18-50 fight off an infection caused by a specific bacteria.

  Recruiting at 2 sites Phase 4 University of Oxford · Liverpool, North West and 1 other locations · NCT06731374

• Evaluating a Pneumococcal Vaccine in Healthy Individuals

  This study is testing a new pneumococcal vaccine in healthy people aged 2 and older to see how well it works and if it's safe.
