美国有线新闻 CNN 美国扩大疫苗接种人群 不再保留第二剂疫苗

A CNN medical analyst¹ says the United States might have passed the peak of new coronavirus cases. A few weeks ago, health officials said hospitalizations related to the disease were at about 132,000 per day. Now, these hospitalizations are down to 124,000 per day. So some improvement there.

美国有线电视新闻网（简称CNN）的一位医学分析人士表示，美国可能已经度过了冠状病毒新增病例的高峰期。几周前，卫生官员表示，冠状病毒相关的入院人数约为每天13.2万人。现在，日均入院人数已减少到12.4万人。情况有所改善。

But a former commissioner² from the U.S. Food and Drug Administration says there's a new variant³ of COVID, a new strain of it that could cause another increase in coronavirus cases. He says the silver lining⁴ there is that a lot of people will have already been infected with the disease and will be immune to it, and a lot of others will be getting a new emergency vaccine⁵.

但是一名美国食品和药物管理局的前专员表示，新冠肺炎出现新变种，即可能导致病例再次增加的新毒株。他表示，一线希望是，很多人已经感染了这种疾病，且将其产生免疫，还有很多人将接种一种新的紧急疫苗。

This is how herd⁶ immunity⁷ is achieved. It's when most of a population becomes immune to a disease and it can happen in two main ways, either enough people have recovered from the illness and developed immunity naturally, or a drug like a vaccine prevents people from getting sick in the first place. Scientists don't know yet if the two approved vaccines⁸ work against the new COVID variant.

这就是实现群体免疫的方式。群体免疫指大多数人对一种疾病产生免疫力，这主要通过两种方式发生，其一是有足够多的人从疾病中康复并自然产生免疫力，另一种是像疫苗这样的药物一开始就预防患病。科学家尚不清楚两种获批疫苗是否能对抗新冠肺炎新变种。

There's also been some confusion about whether the second doses will be available. Drugmakers say each of the approved vaccines requires two shots given a few weeks apart to be fully⁹ effective, and because the government released all of its available doses to try to give as many people as possible their first shot, it's not clear if the second dose will be available to everyone on time.

对于是否能获得第二剂疫区也存在一些困惑。制药商表示，每种获批疫苗都需要间隔几周注射两次才能完全有效，由于政府公布了所有可用剂量，试图让尽可能多的人接种第一剂疫苗，因此目前不清楚第二剂疫苗能否按时提供给所有人。

The Trump¹⁰ administration says it's confident that ongoing¹¹ vaccine production will keep up with demand.

特朗普政府表示，他们有信心对疫苗生产能跟上需求。
