to get vaccinated

This is called "herd immunity", which protects the people who get hurt easily, including those who can't be vaccinated for medical reasons, babies too young to get vaccinated and people on whom the vaccine doesn't work ．

这就是所谓的"群体免疫",它保护那些比较脆弱的人,比如由于医学原因不能接种疫苗的人,年纪太小无法接种疫苗的婴儿,以及接种无效的人。

One customer who gave the company one star wrote: "Called to get a ride and was told, 'vaccinated people aren't allowed in our cars.' Good luck with that business model."

一位给该公司一颗星的顾客写道：“打电话叫车，却被告知‘接种疫苗的人禁止乘车。’祝你在这种商业模式下好运。”
