Recruiting studies
- NCT05559671RecruitingPhase 4
Shingles vaccine safety study for people with lupus
This Phase 4 study checks how safe a shingles vaccine (Shingrix, a non-live vaccine) is for adults with lupus. You might be invited if you have lupus and haven’t had certain shingles or chickenpox-related vaccines recently, and if your lupus symptoms and immune health meet the study rules.

Lower-dose HPV vaccine study for women with HIV
This trial tests whether giving a lower dose of the HPV vaccine can still be effective and safe for women living with HIV. It may be helpful if you need HPV protection and the study’s dose schedule could reduce vaccine burden.
Surrey, British ColumbiaAges 18–45 - NCT05415267RecruitingPhase 3
Boosting COVID protection during long-term immune suppression
This study looks at how well a COVID-19 booster works in adults who need long-term medicines that lower immune response. It aims to see whether immunosuppressed people benefit from booster vaccination safely.
Blacktown, New South WalesAges 18 years+ - NCT05432635RecruitingPhase 1
CAR T-cell and vaccine treatment after stem cell transplant
This Phase 1 study tests a customized immune-cell treatment (CAR T-cells) plus a vaccine given after stem cell transplant for certain aggressive B-cell non-Hodgkin lymphomas. It aims to help your immune system better recognize and attack the lymphoma and to see how safe the approach is.
Duarte, CaliforniaAges 18 years+ - NCT05334706RecruitingPhase 4
Vaccine study to lower HPV spread in HPV-positive women
This Phase 4 study tests whether a 9-type HPV vaccine (9vHPV) can reduce how infectious HPV is and lower the chance of HPV spreading in women who already have HPV16 and/or HPV18. It focuses on specific HPV-positive women recently diagnosed and compares what happens after vaccination.

Vaccine and immunotherapy for KRAS-mutated lung cancer
This Phase 1 study tests a KRAS-targeted vaccine combined with chemo and immunotherapy (nivolumab and ipilimumab) for people with advanced non-small cell lung cancer. It aims to help the immune system recognize and fight tumors with specific KRAS mutations, and to see if the treatment is safe and effective enough to study further.
Baltimore, MarylandAges 18–100 - NCT05242965RecruitingPhase 2
STEMVAC vaccine with pembrolizumab for advanced lung cancer
This trial tests a cancer vaccine called STEMVAC for people with advanced non-small cell lung cancer. The vaccine is given along with ongoing maintenance immunotherapy (pembrolizumab) to see if it can help keep the cancer from growing.
Omaha, NebraskaAges 18 years+ - NCT05127824RecruitingPhase 2
Kidney cancer vaccine made from your own immune cells
This Phase 2 study tests a personalized kidney cancer vaccine made from your own immune cells. It aims to help your immune system recognize and attack clear cell kidney cancer after surgery, potentially lowering the chance of the cancer coming back.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT05096481RecruitingPhase 2
Vaccine for brain tumors in children and young adults
This trial tests a vaccine that may help the immune system fight brain tumors (medulloblastoma, high-grade glioma, and DIPG). It is for patients who have already had standard treatment and whose tumors are still present or have returned.
Aurora, ColoradoAges 3–39 - NCT05098210RecruitingPhase 1
Personalized vaccine made from your tumor’s new immune targets
This Phase 1 study tests a customized vaccine made from “neo-antigens,” which are new targets found in your tumor. It aims to help your immune system fight certain advanced cancers that have not responded well to prior treatment.
Seattle, WashingtonAges 18 years+ - NCT05108818RecruitingPhase 4
Study immune responses after an flu shot in healthy adults
This study gives you a flu vaccine and measures how your immune system reacts, including both “blood immunity” and “cell immunity.” It’s for healthy adults and mainly aims to better understand how well flu vaccines work in people without major health issues.
Philadelphia, PennsylvaniaAges 18 years+ - NCT04948619RecruitingPhase 2
Vaccine response after cancer therapy in kids
This study is checking how well the immune system works and responds to vaccines in children and young adults who have recently finished cancer treatment. It may help doctors understand if vaccines are safe and effective after therapy.
Charlotte, North CarolinaAges 2–21 - NCT04912765RecruitingPhase 2
New immune vaccine plus nivolumab for liver cancer
This trial studies whether an individualized “neoantigen” cancer vaccine given to immune cells (dendritic cells) plus nivolumab can improve outcomes in people with liver cancer and/or colorectal cancer that has spread only to the liver. It focuses on tumors that can be removed with curative surgery (with or without local ablation) and on people with good enough liver and overall health.
SingaporeAges 21 years+ - NCT04697576RecruitingPhase 1
Flu vaccine injected into melanoma tumors for stage I-IV
This trial tests whether injecting a flu vaccine directly into melanoma tumors helps shrink them. It is for people with stage I to IV melanoma who have at least one tumor that can be injected.
Columbus, OhioAges 18–99 - NCT04579588Recruiting
Study flu vaccine immunity in people after COVID-19
This study looks at how well your immune system (your body’s infection-fighting system) responds to a flu vaccine after you’ve had COVID-19. It may help doctors understand why some people have different protection after vaccines.
Palo Alto, CaliforniaAges 9–64 - NCT04573140RecruitingPhase 1
RNA vaccine study for newly diagnosed adult and pediatric brain tumors
This Phase 1 trial studies an “RNA-lipid particle” vaccine given after surgery for certain newly diagnosed brain cancers (glioblastoma in adults, high-grade glioma in children/teens). The goal is to see whether the vaccine is safe and can train the immune system to fight the tumor.
Washington D.C., District of ColumbiaAges 4 years+ - NCT04460235RecruitingPhase 4
Compare two pneumococcal vaccines in adults treated for lymphoma
This trial compares two vaccination plans to see which one works better for preventing pneumococcal infections after lymphoma chemotherapy. You may be randomly assigned to one of the vaccine strategies, and the study checks your immune response.
AngersAges 18 years+ - NCT04329065RecruitingPhase 2
Vaccine with targeted breast cancer drugs before surgery
This Phase 2 trial tests whether adding a cancer vaccine (with GM-CSF) to standard HER2-targeted chemotherapy before surgery improves treatment outcomes for HER2-positive breast cancer. If you join, you’ll receive planned medicine before surgery to treat the tumor, then continue with the study schedule.
Seattle, WashingtonAges 18 years+ - NCT04348747RecruitingPhase 2
Vaccine plus pembrolizumab for breast cancer in the brain
This trial studies whether a personalized immune-cell vaccine (dendritic cell vaccine) combined with pembrolizumab can help control brain metastases from certain types of breast cancer. It may help your immune system better recognize and attack cancer cells in the brain.
Tampa, FloridaAges 18 years+ - NCT04144023RecruitingPhase 1
Vaccine before surgery for HER2-positive breast duct cancer in place
This Phase 1 study tests a vaccine (H2NVAC) given before surgery to help the body fight HER2-expressing ductal carcinoma in situ (DCIS) that has not been removed yet. Because it’s early-stage, the main goal is to check safety and learn how the treatment may work.
Jacksonville, FloridaAges 18 years+ - NCT03942328RecruitingPhase 1/Phase 2
Immune cell vaccine plus checkpoint treatment after liver radiation
This trial tests a combination of a personalized immune cell treatment (made from your own cells) and a pneumococcal vaccine along with an “immune checkpoint” drug after high-dose radiation for certain unresectable liver cancers. The goal is to help your immune system better attack the cancer and to see how safe and effective this approach is.

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.
