Recruiting studies
- NCT06694766Recruiting
Yellow Fever Vaccine Safety and Immune Response in Pregnancy
This study gathers safety and antibody information from women who received their first yellow fever vaccine either during pregnancy or outside of pregnancy. It aims to better understand how the vaccine affects pregnant women and their babies.
ParisAges 18 years+ - NCT01244802Enrolling by invitation
Study of immune memory after yellow fever vaccination
This study looks at how your immune system “remembers” the yellow fever vaccine over time. It may help researchers understand long-term immune protection and how it varies between people.
Decatur, GeorgiaAges 18 years+ - NCT07103148RecruitingPhase 3
Study of a Yellow Fever Vaccine in Young Children
This trial tests a new yellow fever vaccine in young children. It will see if the vaccine is safe and produces a good immune response, including when given with the MMR vaccine.
San Pedro SulaAges 9 months–5 years - NCT03132311RecruitingPhase 4
Yellow fever vaccine study for certain people with HIV
This trial checks whether a yellow fever vaccine is safe and works well in adults with HIV who have relatively healthy immune function. It may help doctors understand the best way to protect people with HIV who have never had this vaccine.
Rio de JaneiroAges 18–59 - NCT07358910Recruiting
Tracking infectious diseases in communities
This study looks at how infections spread in villages in Cambodia. If you live in a participating village, you might help us understand and prevent disease outbreaks.
Phnom Penh, Phnom PenhAges 2–75 - NCT05859490RecruitingPhase 1/Phase 2
Yellow fever vaccine study for adults with past vaccination
This trial studies how well the yellow fever vaccine “17D” stimulates the immune system (the body’s germ-fighting response) in adults who were vaccinated with 17D years ago. It may help researchers understand whether a prior vaccination still provides protection and how strong the immune response is.
Portland, OregonAges 20–49 - NCT05801978RecruitingPhase 4
How long a vaccine’s immune response lasts in adults
This study checks how long your body’s protection signals last after a vaccine. It may help researchers understand which vaccines give longer-lasting immune responses and who may need boosters.
Atlanta, GeorgiaAges 18–50 - NCT07636551Recruiting
Studying Immune Cells in Healthy Unvaccinated Skin
This study examines special immune cells that live in your skin to understand how they work. Researchers will take small skin samples to learn more about your body's natural defenses, which could help develop better vaccines in the future.
AntwerpAges 18–50 - NCT06148025RecruitingPhase 4
Do antibiotics affect vaccine responses?
This study looks at whether taking a short course of antibiotics can change how your body responds to two vaccines (BCG and yellow fever). It may help researchers find ways to make vaccines work better.
Adelaide, South AustraliaAges 18–35 - NCT06718127Recruiting
Study of immune response to yellow fever vaccine
This study looks at how your body's immune system responds to the yellow fever vaccine. It may help researchers understand how well the vaccine protects people.
ParisAges 18–65 - NCT06879327RecruitingPhase 2
Testing different schedules for an infant malaria vaccine
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

Common questions
- Are there clinical trials for yellow fever?
- Yes. Clin2 currently lists 11 recruiting yellow fever 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 yellow fever 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 yellow fever 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.
