Recruiting studies
- NCT07104240Recruiting
Improving HPV vaccination for preteens ages 9-12
This study tests a program designed to help primary care practices increase HPV vaccination rates among adolescents aged 9 to 12 who haven't yet been vaccinated. It aims to find out if providing practices with resources and support can lead to more kids getting the HPV vaccine.

Vaccine plus immunotherapy for a specific liver cancer gene change
This Phase 1 trial tests a personalized peptide vaccine (targeting the DNAJB1-PRKACA fusion) combined with immunotherapy drugs to treat fibrolamellar hepatocellular carcinoma (FLC) or other eligible non-FLC cancers with the same gene fusion. It aims to see whether this immune-based treatment can shrink tumors and improve outcomes safely.

Study of immune response to hepatitis B vaccine
This study looks at how your body's cells respond after getting a hepatitis B vaccine. It may help researchers understand how well the vaccine works.
ParisAges 18 years+ - NCT07534007Recruiting
Shingles vaccine response in patients on immune-modifying drugs
This study tests a new shingles vaccine in people with psoriasis or myelofibrosis, some of whom take immune-modifying medications. Researchers want to understand how well the vaccine works and how the immune system responds in these groups.
Pavia, LombardaAges 18–100 - NCT05916261RecruitingEarly Phase 1
Personalized pancreatic cancer vaccines with pembrolizumab
This early-phase trial tests a personalized cancer vaccine made from your tumor, along with pembrolizumab, to help the immune system attack advanced pancreatic cancer. It may be an option if your cancer has specific immune “targets” and if you meet several health, lab, and infection requirements.
Qionghai, HainanAges 18 years+ - NCT06751849RecruitingPhase 2
Vaccine, immunotherapy, and radiation for advanced lung cancer
This trial tests a combination of a personalized cancer vaccine, an immunotherapy drug (PD-1 inhibitor), and radiation therapy for people with advanced non-small cell lung cancer that has gotten worse after at least two prior treatments. The goal is to see if this approach can help shrink tumors or slow cancer growth.
Nanchang, JiangxiAges 18–70 - NCT07338786Enrolling by invitationPhase 1
Rabies vaccine safety trial for ages 10 to 60
This trial tests a freeze-dried rabies vaccine to see how safe it is when given on different schedules. It may be an option for people who need protection from rabies.
Xuzhou, JiangsuAges 10–60 - NCT07100210RecruitingPhase 1
Study of a new drug for advanced solid tumors that haven't responded to treatment
This trial tests a new drug, IL-22BP/LNP, for people with advanced solid tumors (like soft tissue sarcoma, head and neck cancer, melanoma) that have worsened after standard treatments. The main goals are to see if the drug is safe and tolerable, and to learn if it might help shrink or slow the cancer.
Chengdu, SichuanAges 18–70 - NCT07300462Enrolling by invitationPhase 4
Oral cholera vaccine safety study for children
This trial is for children aged 2 to 14 who have not had a cholera vaccine before. It tests a safe, oral vaccine to prevent cholera, a serious diarrheal disease.
Hefei, AnhuiAges 2–14 - NCT06067555RecruitingEarly Phase 1
Flu vaccine study for healthy adults
This study tests a flu vaccine given just under the skin (intradermal) to see how well it works. It may be a good option if you are a healthy young adult.
New Haven, ConnecticutAges 18–40 - NCT07717840RecruitingPhase 1/Phase 2
RSV vaccine study for adults 60 and older

Common questions
- Are there clinical trials for vaccination?
- Yes. Clin2 currently lists 598 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.
