In addition, infection questions remain unanswered. People who have been vaccinated against asymptomatic or breakthrough infections may be able to infect others with the virus, but it is not yet clear how often it happens.
Many experts have said that it is best to make mistakes on the part of safety and regular testing until the science becomes more definitive, or the vaccination rate rises. For example, at the Olympic Games, frequent testing can help protect a wider range of Japanese with relatively low immunization rates and support staff who may be older and at higher risk.
“It’s those people that I’m really most worried about,” said Dr. Lisa Broseau. a Research consultant at the University of Minnesota Infectious Diseases Research Policy Center.
They are infected with the virus and not only burden the Japanese medical system, but can also be a source of infection. “Everyone is at risk and everyone can get infected,” she said.
According to the Tokyo 2020 Press Office, all Olympic staff and volunteers were provided with vaccination opportunities, but authorities did not provide data on the number of people who received the shots.
Instead of reducing the frequency of tests, Dr. Vinnie said authorities could rethink how they respond to positive tests. For example, if a person is vaccinated and tests positive for asymptomatic, the person must be quarantined, but rather than being quarantined, it would only be necessary to monitor close contact. ..
“You are trying to balance the destructive nature of what someone does when they are vaccinated with the benefits of slowing or stopping the spread of the virus,” Dr. Vinnie said. Told.
