Study how immune-related conditions affect metabolism
This study collects blood and other samples to see how the immune system changes “metabolism” (how your body uses energy) in people with immune-related conditions. Your samples may also be stored for future research and could help researchers better understand immune health.
Bethesda, MarylandAges 18–75 - NCT07527247RecruitingPhase 2
Testing a New Yellow Fever and Dengue Vaccine
This study tests a new vaccine designed to improve protection against yellow fever and dengue fever in healthy adults. Researchers want to see if this vaccine works better than existing ones and is safe.
SingaporeAges 21–59 - NCT06821100RecruitingPhase 1
Thymalfasin to Boost COVID-19 Vaccine Response in Older Adults
This trial tests whether a drug called thymalfasin (thymosin alpha 1) can help older adults (65+) get a stronger immune response from their COVID-19 booster shot. It may be especially helpful for those whose immune systems have weakened with age.
Houston, TexasAges 65–100 - NCT06148025RecruitingPhase 4
Do antibiotics affect vaccine responses?
This study looks at whether taking a short course of antibiotics can change how your body responds to two vaccines (BCG and yellow fever). It may help researchers find ways to make vaccines work better.
Adelaide, South AustraliaAges 18–35 - NCT05306925Recruiting
Arginine supplement study for newborns after major gut surgery
This study looks at whether giving an amino-acid supplement called arginine to newborns after major bowel surgery can improve the baby’s immune response. It may help doctors understand how to support recovery after conditions like necrotizing enterocolitis or certain birth defects.
Liverpool, MerseysideAges 5 months–10 months - NCT06718127Recruiting
Study of immune response to yellow fever vaccine
This study looks at how your body's immune system responds to the yellow fever vaccine. It may help researchers understand how well the vaccine protects people.
ParisAges 18–65 - NCT06842316Recruiting
Study on cannabis-like compounds for inflammatory arthritis
This trial tests whether plant-based compounds similar to cannabis (called phytocannabinoids) can help calm inflammation and improve immune function in people with certain types of arthritis or autoimmune diseases like lupus or Sjögren's disease. It aims to offer a new way to treat these conditions without the 'high' of marijuana.
OrléansAges 18 years+ - NCT04159818RecruitingPhase 2
Adding immune treatments to improve checkpoint drug response in TNBC
This Phase 2 trial tests strategies meant to “prime” the immune system so that immune checkpoint medicines may work better in people with triple-negative breast cancer that has spread (or can’t be fully cured). You might be considered if your cancer has measurable areas that can be biopsied and you meet specific health and prior-treatment rules.
AmsterdamAges 18 years+ - NCT06876467Recruiting
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+ - NCT01132859Recruiting
Study of how immune cells respond in adults
This study looks at how your body’s immune system reacts in different tissues by collecting and storing samples for research. You might be able to join if you’re an adult and can consent, and if you don’t have certain bleeding risks that could make sample collection unsafe.
Bethesda, MarylandAges 18–120 - NCT04871932Recruiting
Study of immune response to a COVID-19 vaccine
This trial studies how your immune system responds after a COVID-19 vaccine. It uses detailed blood tests to understand what changes happen in your immune cells and may help researchers improve future vaccines.
ShanghaiAges 18–50 - NCT05213000Recruiting
Exercise program study to boost vaccine immune response
This study looks at whether regular light-to-moderate exercise around the time of getting an mRNA COVID-19 vaccine can improve your immune response. It may help researchers understand how stress and exercise affect how well vaccines work.
Ames, IowaAges 18–64 - NCT06611072Recruiting
Boosting immune response in ovarian cancer surgery
This study examines how to improve the immune system's response during ovarian cancer surgery, potentially helping the body fight the cancer better. It compares patients with ovarian cancer to women having surgery for non-cancerous conditions.

Common questions
- Are there clinical trials for immune response?
- Yes. Clin2 currently lists 162 recruiting immune response 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 immune response 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 immune response 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.
