Viral respiratory tract infection

This Phase 1 trial tests a personalized approach to treating acute viral respiratory infections using a platform called Dynamic Pathology-Based Therapy (DPBT). Researchers use a predefined algorithm to match each adult participant's specific inflammatory state with a botanical fo…

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 two nasal protective devices (Noseguard and Noseguard Night) in 2000 adults to see if they can reduce the risk of catching respiratory infections like COVID-19 and influenza. Participants will use the devices as directed for 8 weeks, and researchers will track in…

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 follow 1,440 women aged 20 to 45 who had a respiratory viral infection within six months before pregnancy or early in pregnancy. Researchers will track pregnancy complications like gestational diabetes and preterm birth to see if these infections increase risks. T…

This study will look at 5,900 hospitalized adults aged 60 and older to find out which viruses cause severe lung infections. Researchers will test respiratory samples to track common and emerging viruses like flu, RSV, and COVID-19. The goal is to better understand how often these…

This study looks at whether the types of bacteria in a child's gut can influence how sick they get from RSV, a common virus that can cause severe breathing problems in infants. Researchers in Vietnam will compare the gut bacteria and immune responses of 250 children with mild ver…

This study follows 270 preterm babies (born before 32 weeks) from birth to age 3. Researchers will regularly swab their noses to analyze the bacteria and other microbes living there. The goal is to see if the nose microbiome can predict which babies will develop bronchopulmonary …
