CréteilAges 1 day–16 years - NCT04582903Recruiting
Send-in sample collection study for immune response to respiratory viruses
This study collects sent-in samples to better understand how your immune system responds during a COVID-19–like illness and after you recover. It may help researchers learn why some people get sick and others stay uninfected, and how immune protection works over time.
Rockville, MarylandAges 1 day–99 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 - NCT04839757Recruiting
Testing a dengue vaccine plan for kids in the Caribbean
This trial looks at a dengue vaccine strategy in children ages 9 to 17 in Martinique and Guadeloupe. It may help protect kids from dengue, based on how the vaccine is accepted and how the study is carried out.
Fort-de-FranceAges 9–17 - NCT07536308RecruitingPhase 1
Nasal COVID-19 booster vaccine safety trial
This trial tests a new nasal spray COVID-19 booster vaccine. It aims to see if the vaccine is safe and produces a strong immune response when given through the nose and inhaled, in people who have already been vaccinated.
Decatur, 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+ - NCT05146336Recruiting
CytoSorb registry for critically ill patients needing blood treatment

Common questions
- Are there clinical trials for infectious disease?
- Yes. Clin2 currently lists 254 recruiting infectious disease 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 infectious disease 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 infectious disease 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.
