SARS COV-2

This study tests several updated mRNA COVID-19 vaccines designed to target new variants of the virus. About 1,100 adults and children with certain risk factors will receive one of the vaccines to see how well it boosts immunity and how safe it is. The goal is to ensure vaccines r…

This early-stage trial is testing a new nasal spray vaccine called COV2 against COVID-19. Twenty healthy adults who have already had at least two COVID-19 shots will receive two doses of one of two formulations. The study aims to check if the vaccine is safe and whether it boosts…

This early-stage trial tests a new drug called PRS CK STORM, made from a mix of immune and fat cells, to see if it can safely calm the 'cytokine storm'—a dangerous overreaction of the immune system—in people with severe lung infections from COVID-19, flu, or RSV. The study will e…

This study gives a single dose of kisspeptin, a natural hormone, to 40 people with and without Long COVID. Researchers will take frequent blood samples to measure how the brain's reproductive hormone system responds. The goal is to understand if Long COVID disrupts this system, w…

This study follows 200 adults with COVID-19 in intensive care to see how their immune systems change over time. Researchers will collect blood samples at several points during the hospital stay and track health outcomes. The goal is to understand why some patients get worse and t…

This study follows about 800 people who have recovered from COVID-19 to learn how long the virus can stay in different parts of the body, such as the nose, stool, semen, and breast milk. Researchers will also track how the immune system responds and look for any long-term health …
