This trial is testing whether giving the R21 malaria vaccine to infants at different ages (starting at 2 months or 3 months) works as well as starting at 6 weeks. It will help find the best schedule to protect babies against malaria.
Bobo-DioulassoAges 1 month–2 months - NCT06806137RecruitingPhase 3
Chickenpox vaccine study for healthy toddlers
This study tests how well a second dose of an investigational chickenpox vaccine works and how safe it is in healthy children. Your child would get the first dose between 12-15 months old, then a booster 3 months later.

Chickenpox & MMR Vaccine Study for Healthy Toddlers
This study tests a new chickenpox vaccine combined with a standard MMR vaccine (measles, mumps, rubella) in healthy children aged 12-15 months. The goal is to see how well the vaccines work and how safe they are when given as a shot in the arm.
Tucson, ArizonaAges 1 year–1.3 years - NCT07460154Recruiting
Structured review to improve COPD management
This trial tests a structured review process to help people with COPD who have needed multiple steroid pills in the past year. It aims to improve care and prevent future harm from the condition.
North ShieldsAges 35 years+ - NCT06731374RecruitingPhase 4
New pneumonia vaccine study for healthy adults 18–50
This study tests a new pneumococcal vaccine (PCV15) to see how well it protects against carrying the bacteria that can cause pneumonia. Healthy adults aged 18–50 who have not had a pneumococcal vaccine in the last 5 years may join.
Liverpool, North WestAges 18–50 - NCT06740630RecruitingPhase 3

Common questions
- Are there clinical trials for pneumococcal vaccines?
- Yes. Clin2 currently lists 37 recruiting pneumococcal vaccines studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a pneumococcal vaccines trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a pneumococcal vaccines trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
