Public opposition to the Games is growing in Japan as the country struggles to contain a fourth wave of infections which is pushing medical resources to the brink.

Japan reported more than 7,000 new infections on Wednesday, with 969 cases in Games host-city Tokyo.

To forestall a virus outbreak during the event, Japan is preparing to offer vaccinations to about 2,500 Olympic and Paralympic athletes and support staff, using donated shots.
