On Aug. 3, 2020, the University of Oxford and the COVID Symptom Study joined forces to widen access to two clinical trials of potential treatments for COVID-19. The COVID Symptom Study App was developed and is managed by health technology company ZOE, with the research using data from the app being undertaken by academics at King’s College London.

To date, the app had now been downloaded by over 3.5 million people in the UK and has recruited over 800,000 citizen scientists to its Vaccine and Trial Registry.
