Under the rules, all adult foreign air travelers to the U.S. must be fully² vaccinated against COVID-19 before they can board a flight. This is in addition to the current requirement that travelers show proof of a negative COVID-19 test carried out within 72 hours of departure to the U.S.

根据规定，所有前往美国的成年外国航空旅客必须在登机前完全接种疫苗。这是对目前要求前往美国的旅客出示登机前72小时内新冠肺炎检测阴性证明的补充。

The new policies cover travelers from 26 European nations including France, Germany, Italy, Spain, Switzerland and Greece. The rules will also permit conditional³ U.S. entry to flyers from Britain, Ireland, China, India, South Africa, Iran and Brazil.

The administration of former U.S. President Donald Trump⁴ first placed COVID-19-related travel restrictions⁵ on air travelers from China in January 2020. These were later extended to many other countries.

前总统川普领导的美国政府于2020年1月对中国航空旅客首次实施了与新冠肺炎相关的旅行限制。这些限制后来扩展到了其它许多国家。

在整个新冠病毒大流行期间，美国允许了来自150多个国家的国际航空旅客入境。一些专家批评这项政策，因为它包括了新冠肺炎发病率很高的国家。

The new rules affect almost all foreigners flying to the U.S.

这项新规定几乎影响到了所有飞往美国的外国人。

The new policy also affects unvaccinated Americans traveling to the U.S. Now, they must be tested for COVID-19 within a day of travel. They must show proof of the test and its result. And, they have to show proof of purchase of a virus test they are required to take after entering the U.S.

新政策也影响到了未接种疫苗的美国人回国。现在，他们必须在旅行前24小时内接受新冠肺炎检测。他们必须出示检测证明及其结果。而且，他们还得出示一项入境美国后必须要做的病毒检测的购买证明。

The U.S. Centers for Disease Control and Prevention (CDC) says the government will accept full vaccination⁶ of travelers with any COVID-19 vaccine⁷ approved for emergency use by the World Health Organization (WHO). This includes the vaccines⁸ from Pfizer, Moderna and Johnson & Johnson.

美国疾控与预防中心表示，政府将承认旅客完全接种世卫组织批准紧急使用的任何新冠肺炎疫苗。这其中包括辉瑞、莫德纳和强生公司的疫苗。

Other WHO-approved vaccines will also be accepted. These include AstraZeneca and China's Sinovac. The WHO is reviewing Russia's Sputnik V vaccine, but has not yet approved it.

其它世卫组织批准的疫苗也将被认可。其中包括阿斯利康疫苗和中国的科兴疫苗。世卫组织正在审查俄罗斯的卫星V疫苗，但是尚未批准该疫苗。

Separately on Monday, the United States extended pandemic restrictions at land borders with Canada and Mexico. Those rules bar nonessential travel through October 21. Officials did not say if the new vaccination rule for air travel would also be established at border crossings on land.
