Vaccine plus immune drugs for relapsed blood cancers
This early-phase trial tests a personalized-style vaccine (called VSV-hIFNβ-NIS) given alone or with other cancer-fighting medicines, including drugs that help the immune system attack. It is designed for people with certain relapsed or hard-to-treat multiple myeloma, acute myeloid leukemia, or lymphomas, to see if the treatment can shrink tumors and improve outcomes.
Scottsdale, ArizonaAges 18 years+ - NCT03804944RecruitingPhase 2
Vaccine trial for hormone-positive breast cancer
This Phase 2 study tests an individualized vaccine made from your tumor information to help your immune system fight hormone-positive breast cancer. You may be able to participate if you meet specific hormone-receptor, health, and treatment-timing requirements.
Los Angeles, CaliforniaAges 18–90 - NCT03878121RecruitingPhase 1
Ad4-HIV vaccine study for healthy adults and partners
This Phase 1 study tests whether an experimental HIV vaccine (made from a harmless viral vector) is safe and helps the body build immune defenses. It includes healthy volunteers and, in some groups, their close partners, with careful screening and follow-up visits.
Bethesda, MarylandAges 18–65 - NCT03971669RecruitingPhase 4
Blood donor study testing safety of donating in health
This trial studies people who donate blood and checks what happens in your body after donation, focusing on safety and measurements in lab tests. You may be able to join if you are healthy and pass screening labs and health history checks.
Baltimore, MarylandAges 18 years+ - NCT07583654RecruitingPhase 1
Testing a New mRNA Cancer Treatment for Advanced Solid Tumors
This early-stage trial tests a new mRNA-based drug designed to help your immune system fight advanced cancers that haven't responded to standard treatments. The study measures safety, tolerability, and whether it can slow or shrink your tumor.
Chengdu, SichuanAges 18–70 - NCT04006808RecruitingPhase 1/Phase 2
Shingles prevention vaccine study for kids with kidney transplants
This study tests whether an investigational shingles (herpes zoster) vaccine is safe and helps prevent shingles in children who have had a kidney transplant. Because these children take medicines to prevent rejection, the study specifically looks at vaccine effects in this higher-risk group.
BrusselsAges 1–17 - NCT04106115RecruitingPhase 1/Phase 2
Durvalumab vaccine trial for high-risk bladder cancer after BCG
This early-phase trial tests durvalumab given with an experimental bladder cancer vaccine to help stop or slow high-risk bladder cancer that did not respond to or cannot be treated with BCG. It also evaluates safety and how well the treatment works in this setting.

Common questions
- Are there clinical trials for vaccination?
- Yes. Clin2 currently lists 601 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.
