For example, the International Olympic Committee has said it would urge participants to get vaccinated but not require it. About 83% of the U.S. delegation, which includes 613 athletes, have been vaccinated, said Jonathan Finnoff, chief medical officer of the United States Olympic & Paralympic Committee. That means about 100 athletes have not yet received a COVID-19 vaccine.
The Olympics are also hugely unpopular in this year's host country, where polls show 60% to 80% of Japan's residents say the games should not be held this summer.
