But if you took this 30 percent, these 300 people and had them nominate their friends and took the same number of vaccine doses and vaccinated the friends of the 300 -- the 300 friends -- you can get the same level of herd immunity as if you had vaccinated 96 percent of the population at a much greater efficiency, with a strict budget constraint.
でもこの同じ30%の300人に 友人を挙げてもらって 同じ数の予防接種を 300人が挙げた友人達300人に 実施すると 集団免疫と同等の免疫ができます 集団の96%に予防接種したのと同じ効果を 厳しい予算でもずっと効率よく得られるのです
