So this is a common question that we get if we all lived in a bubble and there was no movement of people, this myth might hold true, but, you know, because of travel and movement of people around the world, Even if a vaccine preventable disease has been eradicated from a certain area, it can easily be reintroduced.
所以,這是一個常見的問題,如果我們都生活在一個保麗龍中,沒有人員流動,這個神話可能會成立,但是,你知道,由於世界各地的旅行和人員流動,即使一種疫苗可預防的疾病已經從某一地區被消滅,它也很容易被重新引入。
