Will vaccines be a necessary condition for next year's Olympic Games?

As we all know, due to the COVID-19 epidemic, the Tokyo Olympic Games could not be held as planned this year. After many considerations, we decided to postpone it for one year. But is it safe to postpone it for one year? Many people have put a question mark in their hearts. On this issue, the representative of Japan has made a statement: No matter what the epidemic situation is next year, the Tokyo Olympic Games will be held as scheduled, and the time will be July 23, 221. Is Japan's statement irresponsible? I don't think so. How to prevent the virus, Japan has made many considerations and put forward many constructive measures, such as controlling the number of venues and staff, strengthening nucleic acid detection and so on. When asked about the vaccine, a Japanese spokesman said that even if the vaccine has not been successfully developed, the Olympic Games will be held as scheduled. Of course, it would be best if there is a successful vaccine on the market. These remarks represent Japan's determination to hold the Olympic Games. Japan's bid to host the Olympic Games has already incurred huge losses. If it is postponed again, the losses may never be recovered. So is the vaccine a necessary condition for the Olympic Games? I don't think so. With the strict implementation of anti-epidemic measures in various countries, the epidemic situation in many places has been effectively controlled. Even if there is no vaccine, there will be no large-scale outbreak. Even so, the role of vaccines can not be underestimated. It is a great good thing for all people in the world to have vaccines. Moreover, it is said that the current vaccine has been successfully developed, and it is highly likely that the vaccine will be promoted worldwide next year. It is foreseeable that next year's Tokyo Olympic Games will not be very hot for two reasons. Athletes from many countries will refuse to take part in the competition. There won't be many spectators at the scene. But it must be held. Now we can only expect Japan to make all the preparations and wait quietly for the Olympic Games.
