It is "very unrealistic" the Tokyo Olympics and Paralympics will take place next year unless a coronavirus vaccine has been found by then, says a leading global health scientist.
Professor Devi Sridhar said the development of effective and affordable treatment would be a "game-changer" in whether the postponed Games take place.
The International Olympic Committee and Tokyo 2020 organisers held an executive board meeting this week at which they reiterated their hope the Games can be the "light at the end of the tunnel".
However, IOC coordination commission chair John Coates acknowledged Covid-19 could still affect the rescheduled Olympics, which are due to take place from 23 July-8 August 2021.
