HPV vaccine trial for oropharyngeal cancer patients
This trial tests a therapeutic vaccine for people with HPV16-positive oropharyngeal cancer who have finished curative treatment and are free of disease. The vaccine aims to help the immune system prevent the cancer from coming back.
VillejuifAges 18 years+ - NCT06959420Recruiting
Vaccination during fever: healthcare workers and adults surveyed
This trial asks healthcare workers and adults about their views on getting vaccinated when they have a fever. It aims to understand what people think and do, to help improve vaccination practices.
Saint-EtienneAges 18 years+ - NCT06760208Recruiting
Learning about Prevenar 20 in the real world in Korea
This study is for people who are already getting the Prevenar 20 vaccine (a shot that protects against pneumonia and other infections) as part of their regular care. The researchers want to see how well it works in the real world, so it's a simple way to help improve vaccines for everyone.
SeoulAges 1 month+ - NCT07680582RecruitingEarly Phase 1
Personalized cancer vaccine after surgery for solid tumors
This trial tests a personalized vaccine designed to train your immune system to fight any remaining cancer cells after surgery or during standard therapy. It is for people with solid tumors who are stable and have no signs of disease getting worse.

Mobile health tool to improve childhood vaccines in displaced families
This study is testing a mobile health (mHealth) program to improve childhood vaccination rates among displaced families in conflict-affected areas of Nigeria. If you are a caregiver for a young child or pregnant, living in an IDP camp, you may be able to help researchers see if a phone-based tool makes it easier to get vaccines on time.
Jere, Borno StateAges 1.9 years–1.9 years - NCT05862454Recruiting
Magnesium shots may help avoid steroid during certain immune health issues
This trial studies whether giving a magnesium injection can replace (or avoid) steroids during treatment around times of vaccine, a viral infection, or immune system weakness.

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.
