As public opinion about next month’s Tokyo Olympics continues to sour, Japanese authorities are racing to get vaccination numbers up amid a fourth wave of the virus. Japan, which yesterday passed 750,000 COVID cases since the pandemic began, wants to vaccinate 1 million residents a day. It’s currently delivering half that, and it’s expected that 70% of the country will be unvaccinated by the time the Games’ start on 23 July. Japan’s medicos say the Olympics could become an incubator for a ‘Tokyo variant’ of the virus as athletes, officials, sponsors and journalists arrive from around the world. But having already postponed the Games last year, the Japanese Government and Olympic officials are determined to steam ahead.
