TOKYO (Reuters) - The Tokyo Olympics next July will be a "uniquely risky" event, demanding flexibility from organisers amid the uncertainty of the coronavirus pandemic, particularly if a vaccine has not been rolled out by then, medical experts say.

Japan and the International Olympic Committee made the unprecedented decision last month to delay the Games for a year, as the world battles the virus that has infected 2.3 million people and killed more than 150,000 globally.
