We’re tracking 11 recruiting studies that include Yellow Fever vaccine, each written for real people, not researchers, below.
Recruiting studies
- 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 - 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 - 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+ - 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+ - 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 - 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 - 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 - 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 - 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 - 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 - NCT06843226Recruiting
Dengue vaccine study for children and teens
This study tests if a dengue vaccine (TDV) can reduce hospital stays for dengue. It follows children and teens in areas where dengue vaccination is planned.
Banjarmasin, South KalimantanAges 6–12

Common questions
- Are there clinical trials studying Yellow Fever vaccine?
- Yes. Clin2 currently lists 11 recruiting studies that include Yellow Fever vaccine, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a Yellow Fever vaccine trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is Yellow Fever vaccine an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether Yellow Fever vaccine or a specific trial is right for you.
