SeoulAges 2–100 - NCT06799013RecruitingPhase 1
Testing a new RNA vaccine for Crimean-Congo hemorrhagic fever
This trial is testing an investigational RNA vaccine to see if it is safe and helps your body build immunity against Crimean-Congo hemorrhagic fever, a serious viral disease. The study involves two injections and follow-up visits over several months.
San Antonio, TexasAges 18–64 - NCT05859490RecruitingPhase 1/Phase 2
Yellow fever vaccine study for adults with past vaccination
This trial studies how well the yellow fever vaccine “17D” stimulates the immune system (the body’s germ-fighting response) in adults who were vaccinated with 17D years ago. It may help researchers understand whether a prior vaccination still provides protection and how strong the immune response is.
Portland, OregonAges 20–49 - NCT06694766Recruiting
Yellow Fever Vaccine Safety and Immune Response in Pregnancy
This study gathers safety and antibody information from women who received their first yellow fever vaccine either during pregnancy or outside of pregnancy. It aims to better understand how the vaccine affects pregnant women and their babies.
ParisAges 18 years+ - NCT06624787Recruiting
Rapid test for Crimean-Congo hemorrhagic fever
This trial is developing a quick, point-of-care diagnostic test for Crimean-Congo hemorrhagic fever (CCHF), a serious viral illness. If you have symptoms and are being tested for CCHF, this study could help confirm the diagnosis faster.
ErzurumAges 18 years+ - NCT06212336RecruitingPhase 2/Phase 3
Lassa fever treatment with antiviral combinations
This trial tests different combinations of antiviral drugs (favipiravir, ribavirin, and a steroid called dexamethasone) in adults hospitalized with Lassa fever. The goal is to find the safest and most effective treatment.
Suacoco, Bong CountyAges 18 years+ - NCT05656365Recruiting
Study of genes and immunity in PFAPA and other tonsil problems
This study looks at genetic markers and immune system patterns in people with PFAPA (periodic fevers with mouth sores and throat/neck gland symptoms) or similar tonsil problems. It may help researchers understand why these conditions happen and how they might be better diagnosed or treated.
Washington D.C., District of ColumbiaAges 1 month–99 years - NCT04633603Enrolling by invitation
Study of attitudes toward fever and fever care changes
This study looks at how people think about fever and how fever care works in the healthcare system. You may be asked to record details of fever episodes at home or in outpatient care to help researchers understand real-world fever management.
PécsAges Up to 100 years - NCT01244802Enrolling by invitation
Study of immune memory after yellow fever vaccination
This study looks at how your immune system “remembers” the yellow fever vaccine over time. It may help researchers understand long-term immune protection and how it varies between people.
Decatur, GeorgiaAges 18 years+ - NCT04140578RecruitingPhase 4
Antibiotic prevention for certain liver disease patients
This trial tests whether taking preventive antibiotics can help people with certain liver conditions avoid infections after an endoscopy-related procedure. It may reduce infection risk, but it also requires that you have no signs of infection and haven’t recently taken antibiotics.
TaipeiAges 20–85 - NCT04020536Recruiting
