This early-stage trial will test the safety of a new RSV mRNA vaccine in 60 healthy adults aged 18 and older. Participants will receive either a low dose, high dose, or a placebo (saline) shot. The study aims to see if the vaccine causes any side effects, paving the way for large…

This phase 2 trial tests an inhaled drug called YKYY018 in adults with respiratory syncytial virus (RSV) infection. The goal is to see if the drug can shorten the time until lower respiratory symptoms, like cough and wheezing, improve. Participants receive either YKYY018 or a pla…

This study looks at whether the RSV vaccine given in late pregnancy can help protect babies born to mothers with HIV. RSV is a leading cause of infant hospitalization, and babies exposed to HIV are at higher risk. Researchers will measure antibody levels in mothers and infants to…

This study tests whether a single dose of the RSV vaccine (Arexvy) can reduce moderate-to-severe COPD flare-ups in people who have frequent attacks. Researchers will enroll 320 high-risk patients aged 50+ and follow them for one year. Half will get the vaccine plus standard care,…

This study tests whether the RSV vaccine Abrysvo can help blood cancer patients who have had a stem cell transplant or CAR-T therapy build immunity against RSV. Researchers will measure antibody levels before and after vaccination in 30 adults. The goal is to see if the vaccine t…

This study tests whether a quick, bedside ultrasound of the internal jugular vein in the neck can help tell how severe bronchiolitis is in infants aged 1 to 23 months. Researchers will measure how much the vein's diameter changes with breathing and compare that to standard clinic…

This study evaluates a new diagnostic test called DECIPHER bioassay for detecting Ebola virus. Researchers will use stored blood and cheek swab samples from patients in the Democratic Republic of the Congo to see how well the new test compares to the standard lab method. The goal…

This study evaluates two new diagnostic tests (FORTIFIEDx and DECIPHER) for detecting Ebola and Lassa viruses. Researchers will use stored blood and cheek swab samples from patients in Guinea to see how well these tests compare to the standard PCR method. The goal is to determine…

This study will test a new at-home diagnostic test that aims to detect five respiratory viruses—COVID-19, influenza A and B, RSV, and rhinovirus—from a single nose swab. About 2,000 people with cold or flu symptoms will provide samples in simulated home environments. The test's a…

Clesrovimab is an FDA-approved antibody shot for infants under 8 months entering their first RSV season when their mothers did not get an RSV vaccine in pregnancy. Researchers at Emory University are measuring antibody levels in the blood and noses of 24 healthy infants who recei…

This study tests an investigational vaccine that combines protection against measles, mumps, rubella, and chickenpox (varicella) in a single shot. It will be given as a second dose to healthy children aged 4 to 6 years who have already received a first dose of a similar vaccine. …

This study tests whether a single dose of nirsevimab, an antibody that targets RSV, can prevent respiratory infections in Aboriginal and Torres Strait Islander children aged 6 months. Around 1,000 children will be randomly assigned to receive either the antibody or standard care.…

This study tests a new medicine called SIBP-A16 to see if it can safely prevent RSV in infants under 1 year old, including those born early. About 36 babies will receive either the new drug, a placebo, or an existing RSV drug. The main goal is to check for side effects and how th…

This study tests whether giving the Ervebo Ebola vaccine together with the antibody drug Inmazeb still works to protect people who may have been exposed to Ebola. The vaccine alone takes time to work, while antibodies act fast but might interfere with the vaccine. Researchers wil…

This study tests whether giving a vaccine plus an antibody drug right after high-risk Ebola contact can prevent the disease better than the vaccine alone. About 160 people who have had close contact with an Ebola patient (like touching body fluids or a dead body) will be randomly…

Filoviruses such as Ebola and Marburg cause severe hemorrhagic fevers with high death rates, and doctors know little about rare types like Bundibugyo virus. This observational study follows patients in France with confirmed filovirus disease to record how the illness unfolds. Res…

Researchers are tracking 1,000 hospitalized patients aged 65 and older who test positive for a respiratory virus, including human metapneumovirus (hMPV), influenza, RSV, and others. The study compares how each virus relates to death, organ complications, loss of independence, and…

This study looks at health records of babies born in Scotland to see if those whose mothers received the RSV vaccine (ABRYSVO) during pregnancy have fewer hospital visits for RSV. No new participants are enrolled; researchers will analyze existing data. The goal is to understand …

This study follows 150 adults aged 60 and older who have a respiratory infection (flu, RSV, or COVID-19) or who test negative. Researchers will measure specific immune markers in the blood over 60 days to see how they change from early infection to recovery. The goal is to better…

This study will observe 65 children, aged 1 to 24 months, hospitalized with bronchiolitis at Assiut University Hospital. Researchers will collect information on family, social, and medical factors to identify what makes the illness more severe. The goal is to help doctors predict…
