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…

This trial tests whether a single combined mRNA vaccine, mCombriax (mRNA-1083), can protect adults aged 65 and older against both influenza and COVID-19 as effectively as getting two separate shots on the same day. Researchers will compare how many participants in each group deve…

This trial tests a handheld light device (RD-X19) to see if using it for 5 minutes every other day can prevent upper respiratory infections like COVID-19 and flu. It involves 130 military personnel and their families at a single base. Half will get the real device, half a sham de…

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 early-stage trial tests whether a single dose of pembrolizumab (Keytruda), a drug used for cancer, can safely reduce long-term neurological symptoms like brain fog and dizziness in people with long COVID. Fifteen adults who had COVID-19 at least six months ago and still have…

This study tests a mobile mindfulness program called Lift for people who survived a serious illness in the ICU and now struggle with depression, anxiety, or stress. About 450 adults will use either the Lift app or a health education app for 6 months. The goal is to see if the min…

This early-stage trial tests a single IV dose of placental stem cell vesicles (XoGlo Pro) against placebo in 64 adults with mild to moderate COVID-19. The main goal is safety, with a secondary focus on how quickly symptoms resolve. Researchers aim to see if these tiny cell partic…
