Vaccine for advanced liver, bile duct, or pancreatic cancer
This trial is testing an investigational vaccine (YMN-136) for people with advanced liver, bile duct, or pancreatic cancer that has not responded to standard treatments or is not tolerated. The vaccine aims to help your immune system fight the cancer. It may be an option if standard treatments have failed.
Chengdu, SichuanAges 18–75 - NCT07749911Recruiting
Vaccine effectiveness study for malaria in young children
This study looks at how well the R21/Matrix-M malaria vaccine works in real-life settings for children under 5. If your child is eligible for the vaccine and has a fever, they may be able to join and help us understand the vaccine's impact.
Boromo, Boucle MouhounAges 5 months–5 years - NCT07724106RecruitingPhase 1
NeoOVSV vaccine for ovarian cancer after surgery
This trial tests a personalized vaccine made from your own tumor tissue called NeoOVSV. It is meant to train your immune system to fight any remaining cancer after surgery. The vaccine is a personal treatment because it uses your tumor's unique markers.
Chengdu, SichuanAges 18–75 - NCT07706673Enrolling by invitationPhase 4
Long-term follow-up for HPV vaccine study participants
This study checks on people who got one or two doses of the HPV vaccine (Gardasil 9) during the earlier ESCUDDO study. It helps researchers see how well the vaccine protects over many years, which might lead to simpler vaccination schedules.
Liberia, Guanacaste ProvinceAges 18 years+ - NCT07686380RecruitingPhase 2
IL-15 treatment with or without vaccine for prostate cancer
This trial tests a drug called IL-15 superagonist (with or without a vaccine) for men whose prostate cancer has come back (shown by rising PSA) after they already had targeted radiation therapy. The goal is to see if this treatment can lower or control PSA levels.
Bethesda, MarylandAges 18–120 - NCT07675785RecruitingPhase 2
Malaria Vaccine Study for Women Who Could Become Pregnant in Mali
This study tests an experimental malaria vaccine called PfSPZ-LARC2. Researchers want to learn if it is safe and effective for women who could become pregnant, especially in Mali where malaria is common. You would receive several doses of the vaccine and be followed for a few months.
BamakoAges 18–38 - NCT07676890RecruitingPhase 1
Study of a personalized vaccine for ovarian cancer after surgery
This trial tests a personalized vaccine made from your tumor's genetic material. It is given after surgery to help your immune system recognize and attack any remaining cancer cells, with the goal of preventing the cancer from coming back.
Chengdu, SichuanAges 18–75 - NCT07668271RecruitingPhase 4

Common questions
- Are there clinical trials for vaccination?
- Yes. Clin2 currently lists 575 recruiting vaccination 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 vaccination 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 vaccination 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.
