VOA常速英语2021--5月底前有足够疫苗供成年美国人接种（在线收听）

This is VOA news. Via remote, I'm Marissa Melton. U.S. President Joe Biden has announced that thanks to a new cooperation between two drug companies, there will now be enough doses of the coronavirus vaccine available for the entire adult population in the United States by the end of May. The president added, however, that it will take longer than that to inoculate everyone and he urged people to remain vigilant by wearing masks. Mr. Biden had previously said there would be enough doses by the end of July. On Tuesday, he said the faster production of the vaccine was in part the results of an agreement by the pharmaceutical giant Merck & Co. to help manufacture the new Johnson & Johnson coronavirus vaccine. The unusual agreement between the two rivals announced on Tuesday was brokered by the White House. The U.S. Food and Drug Administration approved the Johnson & Johnson vaccine for emergency use last week. But the company has encountered unexpected production problems.

欢迎收听美国之音新闻。我是玛丽莎·梅尔顿，为您远程报道。美国总统拜登宣布，由于两家制药公司的新合作，到5月底，美国将有足够剂量的冠状病毒疫苗可供所有成年人注射。然而，拜登总统补充说，让所有人接种疫苗需要更长的时间，因此他敦促人们戴上口罩保持警惕。拜登此前曾表示美国到7月底将会有足够的疫苗剂量。周二，他表示，疫苗生产速度加快的部分原因是制药巨头默克集团达成协议，帮助生产新的强生新冠疫苗。这两个竞争对手周二宣布的不同寻常的协议是由白宫斡旋达成的。美国食品和药物管理局上周批准强生疫苗的紧急使用。但强生公司遇到了始料不及的生产问题。

Texas is lifting its COVID-19 mask mandate. Republican Governor Greg Abbott's announcement on Tuesday makes Texas the largest U.S. state to do away with a face-covering order. The new rule takes effect on March 10. The decision comes as governors across the United States are easing coronavirus restrictions despite warnings from health experts that the outbreak is far from over. Texas has seen a sharp plunge in cases and hospitalizations in recent weeks. More than 42,000 people have died from the virus in Texas, however. It trails only California and New York.
