Immunization clinical trials
Below are recruiting immunization clinical trials, each written for real people, not researchers. We’re tracking 1,063 recruiting studies, each written for real people, not researchers, below.
Recruiting studies
- NCT05162638Enrolling by invitation
Immune study in MS and healthy adults using a special tube
This study compares immune (defense system) “profiles” between people with multiple sclerosis (MS) and healthy volunteers. It involves a thoracic duct cannulation procedure and several MRIs to see how immune cells behave and whether a specific immune pattern is different in MS.
Philadelphia, PennsylvaniaAges 18–40 - NCT05131594Enrolling by invitation
Study immune response in Long COVID patients
This trial studies how your immune system responds in people with Long COVID after a past COVID-19 infection. It may help researchers understand why symptoms linger and how the body’s response could be targeted.
Pasadena, CaliforniaAges 18 years+ - NCT05095701Enrolling by invitationPhase 4
Study tracks lasting protection from a live chickenpox vaccine
This trial follows people who previously took a chickenpox (varicella) vaccine to see how long their immune protection lasts. It may help explain who stays protected over time and for how long.
Xuchang, HenanAges 1–17 - NCT04708535Enrolling by invitation
Study how fat changes affect insulin resistance after bariatric surgery
This study looks at how your body’s fat under the skin and inside the abdomen may affect “insulin resistance,” a common problem linked with blood sugar control. It’s for people who are scheduled for bariatric (weight-loss) surgery, to learn more before and after surgery.
Stanford, CaliforniaAges 30–65 - NCT04363047Enrolling by invitation
Study of immune cells in people linked to COVID-19
This study looks at immune (infection-fighting) cells in people who have previously joined certain healthy volunteer research groups. It may help researchers better understand how the immune system responds to coronavirus infections, including COVID-19.
Manchester, Greater ManchesterAges 18 years+ - NCT04323566Enrolling by invitationPhase 2
Rituximab for OCD or psychosis linked to immune inflammation
This trial tests rituximab (an immune system medicine) to see if it can reduce OCD symptoms and/or psychosis when there are signs the immune system may be involved. You may be considered if other standard psychiatric treatments have not helped enough and your illness seems relatively recent with possible inflammation clues.
UppsalaAges 18–55 - NCT03170141Enrolling by invitationPhase 1
T-cell therapy for recurrent brain tumor
This Phase 1 study tests modified immune T-cells to treat recurrent glioblastoma (a fast-growing brain tumor) that can be seen on scans. Because it’s early-stage, the goal is mainly safety, but you may be helping researchers understand if the treatment can shrink tumors.
Shenzhen, GuangdongAges 6–70

Common questions
- Are there clinical trials for immunization?
- Yes. Clin2 currently lists 1,063 recruiting immunization 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 immunization 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 immunization 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.
