普通の会話に中でも話題として出るだろうと思いますが、そんな時集団免疫であるとか単語が出ると思います。A Herd Immunityがその単語、通常から目を通して置かないと出てきません。
(CNN)After months of effort to limit the spread of the coronavirus in the United States, herd immunity has emerged as a controversial topic.
White House Coronavirus Task Force member Dr. Scott Atlas responded to a report on Monday that claimed he is a proponent of a "herd immunity" strategy to combat Covid-19. "I've never advocated that strategy," Atlas said at a press conference in Florida.
Such an approach -- similar to what was pursued in Sweden -- would mean that many people nationwide would have to get sick with the coronavirus in order to build up a natural immunity across communities. As the virus spreads and sickens people, many could die in the process.
