This large study tested the Oxford-AstraZeneca COVID-19 vaccine (ChAdOx1 nCoV-19) in over 10,000 healthy UK adults aged 18 and older. The goal was to see if the vaccine safely prevents symptomatic COVID-19. Participants received either the vaccine or a control shot, and researche…

This study tested a new COVID-19 vaccine called ChAdOx1 nCoV-19 in over 1,000 healthy adults aged 18-55 in the UK. The goal was to see if the vaccine is safe, triggers an immune response, and can prevent COVID-19. Participants received either the vaccine or a comparison shot, and…

This study tests an experimental drug called SPI-1005 (ebselen) in adults hospitalized with severe COVID-19. Participants receive either the drug or a placebo to see if the drug is safe and helps improve recovery. The trial is randomized and double-blind, meaning neither patients…

This study looked at whether giving plasma (the liquid part of blood) from people who recovered from COVID-19 could help critically ill patients fight the virus. The plan was to collect plasma from up to 240 recovered donors and give it to sick patients. However, the plasma donat…

This study tested whether breathing in nitric oxide gas can improve oxygen levels in severely ill COVID-19 patients who are on ventilators. Researchers enrolled 200 adults in the ICU with confirmed COVID-19 and severe breathing problems. Patients received either standard care plu…

This study tested two drugs, ruxolitinib and fostamatinib, in hospitalized adults with mild to moderate COVID-19 pneumonia. The goal was to see if either drug could prevent the disease from becoming severe. 185 patients were randomly assigned to receive one of the drugs or standa…

This study tested a 30-week walking program for cancer survivors who had been hospitalized with COVID-19. The goal was to see if the exercise was safe and caused few side effects. Only 3 people took part, so the results are very early and not conclusive.

This study followed 324 people who had close contact with a confirmed COVID-19 case to see how long they shed the virus. Participants provided nasal swabs and reported symptoms over 12 days. The goal was to understand transmission risks and help shape public health policies.

This completed study followed 829 people, including healthcare workers and a comparison group, over several years to understand how SARS-CoV-2 spreads and who gets sicker. Researchers collected swabs, blood, and saliva samples along with survey data. The goal was to identify risk…

This completed study from France enrolled 373 people who came to the emergency room with suspected COVID-19. Researchers checked routine blood markers to see if any could predict which patients would later get worse and need intensive care. The goal was to find simple, low-risk t…

This completed study observed 199 adults hospitalized with confirmed COVID-19. Researchers tracked patient characteristics, treatments used, and how the disease progressed over time. The goal was to answer important questions about the natural history of COVID-19 to help guide fu…
