Recruiting studies
- NCT06824519RecruitingPhase 1/Phase 2
Quadrivalent flu vaccine trial for adults
This trial tests a new quadrivalent influenza (flu) vaccine in adults 18 and older. It aims to see if the vaccine is safe and helps protect against the flu. You may be able to join if you are generally healthy and have not had the flu or a flu shot recently.
Shijiazhuang, HebeiAges 18 years+ - NCT05648448RecruitingPhase 2
Early flu antiviral trial for adults with confirmed influenza
This Phase 2 study compares antiviral medicines in adults who have early, flu-like symptoms and test positive for influenza. It aims to see which antiviral treatment works best and is safe for people treated soon after symptoms start.
Minas GeraisAges 18–60 - NCT05332899RecruitingPhase 1
Flu challenge study in healthy adults to test an investigational approach
This Phase 1 study tests an investigational influenza (flu) approach in a carefully selected group of healthy adults. It may help researchers understand how the flu challenge works and how well the treatment performs and is tolerated.
Atlanta, GeorgiaAges 18–49 - NCT05108818RecruitingPhase 4
Study immune responses after an flu shot in healthy adults
This study gives you a flu vaccine and measures how your immune system reacts, including both “blood immunity” and “cell immunity.” It’s for healthy adults and mainly aims to better understand how well flu vaccines work in people without major health issues.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06807840Recruiting
Flu infection study at Penn Medicine
This study looks at how people's immune systems respond to the flu. If you have a positive flu test at a Penn Medicine location and are 18 or older, you may be able to join.
Philadelphia, PennsylvaniaAges 18 years+ - NCT06573008RecruitingPhase 3
Testing GP681 Tablets for Flu in High-Risk Patients
This study tests an oral tablet called GP681 for people with flu who are at higher risk of serious complications. It compares the new drug to a placebo to see if it helps reduce symptoms faster.
ChizhouAges 12 years+ - NCT06355232RecruitingPhase 1
Oral vaccine for COVID-19 and flu
This study tests an experimental oral vaccine that may protect against both COVID-19 and the flu. Researchers want to see if it's safe and how the body responds.
Adelaide, South AustraliaAges 18 years+ - NCT07215858RecruitingPhase 2
Testing a new flu vaccine against H1N1 flu
This study tests an experimental flu vaccine (BPL-1357) in healthy volunteers who will later be exposed to H1N1 flu virus in a controlled setting, to see if the vaccine can prevent or reduce illness.
Bethesda, MarylandAges 18–55 - NCT07215871Enrolling by invitationPhase 1
Second H10N7 flu challenge for prior participants
This study tests whether people who have already been exposed to a lab-made H10N7 flu virus can be safely exposed again. It checks how their immune system responds and how long they shed the virus, in a controlled, isolated setting.
Bethesda, MarylandAges 18–55 - NCT06684379RecruitingPhase 1/Phase 2
Two Doses of PRS CK STORM for Severe Viral Pneumonia
This study tests a new drug called PRS CK STORM to see if it can safely calm the body's overactive immune response (cytokine storm) in people with severe pneumonia from COVID-19, flu, or RSV who need oxygen. It aims to reduce inflammation and improve recovery.
Alcalá de Henares, MadridAges 18 years+ - NCT07464314RecruitingPhase 1
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.
Anniston, AlabamaAges 65–85 - NCT07305207RecruitingPhase 1
Influenza H3N2 infection study for pandemic preparedness
This study gives healthy adults a controlled dose of influenza H3N2 virus to learn how the body responds. The goal is to build a model that can help develop better vaccines and treatments for future flu pandemics.
Halifax, Nova ScotiaAges 18–45 - NCT06848309Recruiting
Immune response study for influenza or COVID-19
This study looks at how your immune system fights off flu or COVID-19. If you have a current or recent infection, or if you've been vaccinated in the past year, you may be able to join.
St Louis, MissouriAges 18–60 - NCT07177417RecruitingPhase 4
How the immune system responds to FluMist in the airways
This study tests how the immune system in your nose and airways responds to the FluMist nasal spray flu vaccine. It may help doctors understand why some people get better protection from the flu.
St Louis, MissouriAges 18–40 - NCT07169318RecruitingPhase 1
Safety study of VNT-101 in healthy adults
This first-in-human study tests the safety of a new medicine called VNT-101. Healthy adults aged 18 to 59 who do not smoke and have no major health problems may be able to join. The goal is to see how the body handles the drug and if it is safe.
Overland Park, KansasAges 18–59 - NCT07358910Recruiting
Tracking infectious diseases in communities
This study looks at how infections spread in villages in Cambodia. If you live in a participating village, you might help us understand and prevent disease outbreaks.
Phnom Penh, Phnom PenhAges 2–75 - 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.

Common questions
- Are there clinical trials for influenza, human?
- Yes. Clin2 currently lists 17 recruiting influenza, human 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, human 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, human 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.
