It hasn't been fully tested. It hasn't been approved yet. But they came running to get a place in the queue for the vaccine. Anyone can turn up, pay the fee and get the jab here and now.
言语间透露出一种信息:你们怎么可以拿人民当小白鼠,置群众的生命安全于不顾呢?
It wasn't that long ago that people were queuing for Covid-19 tests, but now it's the vaccine. And this isn't part of a clinical trial. What's happening here in China is it's being rolled out to the public. You turn up, pay your money, you get your number and then over there you get in the queue and in the next few hours that clinic is going to open and people are going to get the vaccine.
The UK was in the queue in one way when this vaccine gets the formal go-ahead, though. China has pledged to help developing nations first and likely the ones most favored by this country.
