Crato, CearáAges 9–14 - NCT06484686Enrolling by invitationPhase 4
Long-term immunity study of chickenpox vaccine booster
This study follows up people who were in a previous phase 3 chickenpox vaccine trial. It checks how long protection from a booster dose lasts, by taking a blood sample.
Zhengzhou, HenanAges 8–16 - NCT06455852Recruiting
How well does the cholera vaccine protect you?
This study looks at how well the cholera vaccine and past infections protect people from getting cholera. It may help researchers understand who stays protected and for how long.
DhakaAges 2–80 - NCT06355232RecruitingPhase 1
Oral vaccine for COVID-19 and flu
This study tests an experimental oral vaccine that may protect against both COVID-19 and the flu. Researchers want to see if it's safe and how the body responds.
Adelaide, South AustraliaAges 18 years+ - NCT06262776Recruiting
Shingles vaccine safety study for transplant recipients
This trial tests whether the shingles vaccine (RZV) is safe and works well for organ transplant recipients and their household members. It also includes people on dialysis or certain immunosuppressants.
Adelaide, South AustraliaAges 18 years+ - NCT06181656Recruiting
Pneumonia Vaccine Study for Esophageal and Liver Cancer Patients
This trial studies how well the pneumonia vaccine works in people with esophageal or liver cancer who have low white blood cell counts after chemoradiation. It aims to see if the vaccine can still protect them from infection.
Houston, TexasAges 18 years+ - NCT06029933Recruiting
Comparing two flu vaccines for older adults
This study compares two types of flu shots for people 65 and older to see which works better. If you are a Kaiser Permanente member and get your flu shot at a Kaiser facility, this trial looks at your health records to see how well the vaccine protected you.
Oakland, CaliforniaAges 65 years+ - NCT05985681RecruitingPhase 1
Vaccine to prevent HPV-related cancers
This trial tests a new vaccine called RG1-VLP that may help prevent cancers caused by HPV. It is for healthy women who have not had an HPV vaccine before and are willing to follow study procedures.
Madison, WisconsinAges 18–60 - NCT05984849Recruiting

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.
