Amid growing opposition and COVID-19 fears, the International Olympic Committee (IOC) reassured Japan on Wednesday that the Tokyo Olympics would be safe for athletes and the host community.
Speaking in Tokyo alongside senior Japanese officials, IOC chief Thomas Bach said he believed more than 80% of residents of the Olympic Village would be vaccinated or booked for vaccination ahead of the Games set to start on July 23.
He rejected growing calls to cancel the global sporting showpiece, already delayed once due to the pandemic, saying that other sporting events had proved the Olympics could go ahead with strong COVID-19 precautions.
"Together with our Japanese partners and friends, I can only reemphasize this full commitment of the IOC to organize safe Olympic and Paralympic games for everybody," Bach said.
"To accomplish this, we are now fully focused on the delivery of the Olympic Games."
Less than 30% of medics in Japan's major cities have been vaccinated against the coronavirus, with just 65 days left to the start of the Olympics, the Nikkei newspaper said.
Cabinet figures showed this week that three months into Japan's vaccination push, less than 40% of its medical workers were fully inoculated.
The problem is especially pronounced in the capital, Tokyo, which plays host to the Games, and other large population centers, where the rate of fully vaccinated medical workers was less than 30%, the Nikkei added.
Much of the vaccine supply was concentrated in large hospitals, and there had been problems in the reservation systems for medical staff, it said.
The slow pace of vaccinations of doctors and nurses has been among the complaints cited by medical groups that oppose the Games.
Bach said the IOC would do its part to keep the Japanese public safe, by having additional medical personnel as part of the NOC delegations to support the medical operations and the strict implementation of the COVID 19 countermeasures.
Much of Japan, including the key cities of Tokyo and Osaka, is under a state of emergency until month-end to rein in infections. The southern prefecture of Okinawa will request its own emergency declaration as new infections reached record highs, it said on Wednesday.
Japan aims to inoculate most of its 36 million people older than 65 by the end of July. It hopes to deliver about a million shots a day, or three times faster than the current pace to reach that target.
So far, just 3.7% of the population of 126 million have received at least one vaccine shot, the lowest rate among wealthy countries. Initially, the holdup was scant supplies of the vaccine developed by Pfizer Inc. and BioNTech SE, the only one approved by regulators.
But arrivals of the Pfizer vaccine have increased dramatically in May, and Japan is expected to approve Moderna Inc.'s candidate this week for use in mass vaccination centers. The shot developed by AstraZeneca PLC is also being considered by domestic regulators.
As supply bottlenecks eased, problems with vaccine reservation systems and manpower shortages have cropped up. The government is looking into letting pharmacists give the injections, after a similar move regarding dentists last month.
