Recruiting studies
- NCT07040202Recruiting
Immune system study for dengue, flu, and sepsis patients
This study looks at how the immune system responds to dengue, flu, and sepsis. It may help doctors understand these illnesses better and improve future treatments.
Kampong SpeuAges 2 years+ - NCT06998251Recruiting
Immune response to strep pneumonia in older adults
This study looks at how the immune system in the nose and throat reacts to Streptococcus pneumoniae bacteria and viruses in adults aged 60-85. It may help researchers find better ways to prevent or treat pneumonia.
GenevaAges 60–85 - NCT05291676RecruitingPhase 2
Study how vaccines work in aging and frailty adults
This trial studies how well your immune system responds to a vaccine in people who are younger adults or, especially, older adults and those with frailty. Your participation may help researchers understand why vaccine responses can differ with age.
New Haven, ConnecticutAges 21 years+ - NCT06067555RecruitingEarly Phase 1
Flu vaccine study for healthy adults
This study tests a flu vaccine given just under the skin (intradermal) to see how well it works. It may be a good option if you are a healthy young adult.
New Haven, ConnecticutAges 18–40 - NCT06907667Recruiting
Do timing of flu shot affect protection in kidney failure?
This study looks at whether getting a flu shot at a different time of day affects how well it works in people with chronic kidney failure, including those on dialysis or with a kidney transplant. Researchers want to see if timing can improve the body's immune response to the vaccine.
Nice, Alpes-MaritimesAges 18–100 - NCT06859333RecruitingPhase 1
Safety study of Ingavirin Forte in healthy volunteers
This trial tests how safe and tolerable different doses of Ingavirin Forte are in healthy people. It helps find the right dose for future studies.
MoscowAges 18–45 - NCT06850298Recruiting
H5N1 milk detection study
This study looks for the H5N1 virus in the milk of healthy adults. If you are generally healthy and between 18 and 64, you may be able to help by providing milk samples to see if the virus can be detected.
Atlanta, GeorgiaAges 18–64 - NCT05045612RecruitingPhase 4
Antibiotics for certain viral lung infections in hospitalized adults
This trial studies whether giving antibiotics affects recovery in adults hospitalized with moderately severe infections caused by specific viruses (influenza, parainfluenza, RSV, or hMPV). It may help show when antibiotics are helpful or unnecessary for viral airway illness.
BergenAges 18 years+ - NCT06692400Recruiting
Suctioning, pain, and blood markers in intubated patients
This study looks at how routine suctioning of the breathing tube affects pain levels and certain substances in the blood in adults who are on a breathing machine for serious infections like flu, pneumonia, COVID, or sepsis. It may help doctors better understand and manage your comfort during this procedure.
Loma Linda, CaliforniaAges 18 years+ - NCT06664151RecruitingEarly Phase 1
Flu vaccine injected into skin cancer before surgery
This study tests whether injecting the seasonal flu vaccine directly into a skin cancer tumor can help the immune system attack it. You would receive the injection before your scheduled surgery to remove the cancer.
Boston, MassachusettsAges 18 years+ - NCT06635525Recruiting
How kidney failure affects your flu shot response
This study looks at how well the flu vaccine works in people with kidney failure who are on dialysis compared to healthy people. It will help doctors understand how kidney problems affect the body’s immune response to vaccination.
MilanAges 18–70 - NCT06417762Recruiting
A study testing social media health messages for community health workers
This trial teaches community health workers how to find and share true health information on social media, and how to spot and stop false information. It aims to reduce illness from respiratory viruses in seven communities.
Chicago, IllinoisAges 18–99 - NCT06160128Recruiting
COVID-19 treatment outcomes in veterans
This study looks at how well different COVID-19 treatments work in Veterans. By reviewing health records, researchers hope to find which medications help the most.
Portland, OregonAges 18 years+ - NCT05801978RecruitingPhase 4
How long a vaccine’s immune response lasts in adults
This study checks how long your body’s protection signals last after a vaccine. It may help researchers understand which vaccines give longer-lasting immune responses and who may need boosters.
Atlanta, GeorgiaAges 18–50 - NCT05384288Recruiting
How kids with blood cancers respond to the flu vaccine
This study looks at how children with blood cancers respond to the seasonal flu shot. It may help doctors understand what protection the vaccine provides for pediatric oncology patients.
Memphis, TennesseeAges Up to 18 years - NCT05266222Recruiting
Collecting respiratory virus samples for a research library
This study collects samples from people who have or might have a cold/respiratory virus, then stores them for future research. It may help researchers better understand respiratory germs and develop better treatments.
Bethesda, MarylandAges 3 years+ - NCT04772170Recruiting
Study wearable and symptom monitoring during respiratory virus challenges
This observational study looks for digital health patterns during studies where people are intentionally exposed to a respiratory virus. If you join a respiratory virus challenge at NIH, you may help researchers discover better ways to monitor and understand illness using wearable devices and shared health data.
Bethesda, MarylandAges 18–65 - NCT04664569Recruiting
Study of treatments for bacterial meningitis in children
This study enrolls children and newborns with suspected or confirmed bacterial meningitis. The goal is to understand and improve care for serious infections that affect the lining around the brain.
CréteilAges 1 day–18 years - NCT03501576Recruiting
Testing a flu or COVID vaccine response in people with lymphoma
This study checks how your immune system responds after getting a vaccine. It focuses on people with different types of lymphoma, aiming to learn which immune responses can be measured and whether the vaccines are safe for you.
Atlanta, GeorgiaAges 18 years+ - NCT01386424Recruiting
Healthy adult check-in for future infectious-disease volunteer studies
This study enrolls healthy adults to help set up future research studies about infectious diseases. If you qualify, you may be asked to join later “healthy volunteer” experiments and allow your samples to be stored for future research.
Bethesda, MarylandAges 18–65

Common questions
- Are there clinical trials for influenza?
- Yes. Clin2 currently lists 116 recruiting influenza 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 influenza 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 influenza 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.
