RSV vaccine study for healthy older adults
This study tests an RSV vaccine to see if it is safe and helps your immune system fight the virus. It's for older adults who are generally healthy, and it may help protect you from severe RSV illness.
Scottsdale, ArizonaAges 60 years+ - NCT07801625Recruiting
How eyes and nose react to grass allergy
This study looks at how people with and without grass allergies react when a small amount of grass allergen is put into the eye. It aims to understand the immune response in the eyes and nose, which may help improve allergy treatments.
Kingston, OntarioAges 18–70 - NCT07750171Recruiting
How smoking affects healing around dental implants
This study looks at how smoking affects the body's immune response around dental implants that are healthy or have mild gum disease. It may help us understand why some implants develop problems and could lead to better care for smokers with implants.
Ankara, AnkaraAges 21–75 - NCT07757347Recruiting
Fructose and aging in healthy adults
This trial is testing how healthy adults process fructose (a type of sugar) as they age. You may participate if you are generally healthy and don't have certain conditions like gut diseases or metabolic problems.
ViennaAges 18 years+ - NCT02480283Recruiting
Study of cannabis smoke and lung immune response
This study compares people who smoke cannabis daily with people who have never used cannabis. It looks at how cannabis smoke affects lung stress and the lungs’ immune defenses, using health tests and urine screening to keep participants safe.
Aurora, ColoradoAges 18–55 - NCT07698600RecruitingPhase 1
Safety test of a new HIV vaccine in adults with or without HIV
This study tests a new RNA-based vaccine called BNT168 to see if it is safe and how the body responds to it. It is for healthy adults with or without HIV, and those with HIV will pause their regular treatment for a while during the study.
Houston, TexasAges 18–50 - NCT07696884Recruiting
Vascular graft and endograft infection study
This study looks at how the body responds to infections in artificial blood vessels (vascular grafts or endografts). It may help understand why some people get infections and how to better treat them.
AarhusAges 18 years+ - NCT06667063Recruiting
Immune response study for COVID-19 and flu
This study looks at how your immune system responds to COVID-19 or the flu. It may help researchers understand these infections better, whether you are currently sick or healthy.
Wuhan, HubeiAges 18 years+ - NCT07660198RecruitingPhase 3
Pneumonia vaccine catch-up study for kids and teens
This trial tests a catch-up pneumococcal vaccine for children and adolescents who may have missed some doses. It aims to see how safe and effective the vaccine is in healthy kids aged 15 months to 17 years.

LM103 vaccine with PD-1 for advanced solid tumors
This trial tests a new personalized cancer vaccine (LM103) combined with an immunotherapy drug (PD-1) for people with advanced solid tumors that have stopped responding to standard treatments. The goal is to see if this combination is safe and can help shrink tumors.

Testing a combined flu and COVID-19 mRNA vaccine in older adults
This trial is testing whether a new mRNA vaccine that targets both seasonal flu and COVID-19 is safe and creates a strong immune response. It may offer an easier way to protect against two illnesses with one shot.

Common questions
- Are there clinical trials for immune response?
- Yes. Clin2 currently lists 152 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.
