Personalized immune cell therapy plus a CMV vaccine
This Phase 1 study tests genetically modified immune cells (made from your own blood) plus a vaccine aimed at controlling CMV-related lymphoma. It’s for adults with intermediate or high-grade B-cell non-Hodgkin lymphoma who can’t get (or don’t want) certain standard stem-cell transplant options.

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 - NCT05868733RecruitingPhase 2
Lassa fever vaccine study for people in West Africa
This trial tests an investigational vaccine to prevent Lassa fever, a serious illness found in parts of West Africa. People in different age groups will get the vaccine or a placebo and be followed to see if it’s safe and helps the immune system respond.

Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06146088RecruitingPhase 4
EV71 Vaccine Consistency Study for Children
This study tests three batches of an EV71 vaccine (which prevents hand, foot, and mouth disease) to see if they work the same. Your child would receive two doses, several weeks apart, and have blood tests to check their immune response.
Baoji, Shaan XIAges 6 months–2.9 years - NCT06156150Recruiting
B7-H4 protein in tumor vaccine for glioma
This study looks at a protein called B7-H4 to help create a potential vaccine for glioma (a type of brain tumor). It uses a small tissue sample taken during your surgery to check if the vaccine might work for you.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT06253494RecruitingPhase 1/Phase 2
Combination therapy trial for advanced endometrial cancer
This trial tests a combination of three drugs (pembrolizumab, lenvatinib, and an immune booster called N-803) plus a personalized vaccine made from your own cells, all aimed at helping your immune system fight advanced or metastatic endometrial cancer that has HER2 protein on its surface.
Bethesda, MarylandAges 18–120 - NCT06254326RecruitingPhase 1
Immune cell therapy for recurrent oligodendroglioma
This trial tests a personalized immune cell therapy for adults with a specific type of brain tumor (oligodendroglioma) that has come back. The treatment uses your own immune cells to target the tumor.

Common questions
- Are there clinical trials for vaccination?
- Yes. Clin2 currently lists 600 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.
