VOA常速英语2021--美疾控--学校可以在教师未接种疫苗的情况下重新开放（在线收听）

This is VOA news. Reporting by remote, I'm David Byrd. The head of the U.S. Centers for Disease Control and Prevention says that schools can safely reopen even if teachers do not get coronavirus vaccines. AP's Sagar Meghani has details. The CDC's vaccination plans prioritize teachers as essential workers but many have not gotten the shots yet. Some teachers unions are refusing to allow in-person instruction to resume until they do. But CDC Director Rochelle Walensky says that's not necessary. "Vaccination of teachers is not a prerequisite for the safe reopening of schools," saying data show social distancing and mask-wearing can significantly reduce virus spread in schools. President Biden is pushing for nearly all K-8 schools to reopen in his first 100 days. Sagar Meghani, Washington.

欢迎收听美国之音新闻。我是大卫·伯德，为您远程报道。美国疾病控制与预防中心的负责人表示，即使教师没有接种冠状病毒疫苗，学校也可以安全地重新开放。请听美联社记者萨加尔·梅加尼带来详细报道。美国疾病控制与预防中心的疫苗接种计划将教师列为优先接种的主要工作人员，但许多教师尚未接种疫苗。一些教师工会拒绝允许恢复线下授课，直到这些教师接种疫苗。但是美国疾病控制与预防中心主任罗谢尔·瓦伦斯基表示，没有这个必要。“教师接种疫苗并不是学校安全重新开学的先决条件，”数据显示，保持社交距离和戴口罩可以显著减少病毒在学校的传播。拜登总统正在推动几乎所有的K-8学校在其就任前100天重新开学。萨加尔·梅加尼，华盛顿报道。

A new study appears to vindicate Britain's decision to delay the second virus vaccine dose. AP correspondent Charles De Ledesma reports. Health Secretary Matt Hancock says research showing a single dose of the COVID-19 vaccine developed by Oxford University and AstraZeneca provides a high level of protection for 12 weeks supports the government's strategy of delaying the second shot so more doses can be delivered to more people. Hancock's comments came after Oxford says there's evidence the vaccine cuts transmission of the virus by two-thirds and prevents serious disease. The study has not been peer-reviewed yet but has been greeted with excitement by British officials under pressure to justify their decision to delay the second dose. Charles De Ledesma, London.

一项新的研究似乎证明了英国推迟第二次新冠疫苗接种的决定是正确的。请听美联社记者查尔斯·德·莱德斯马报道。英国卫生部长汉考克表示，研究显示，单剂接种牛津大学和阿斯利康公司开发的新冠疫苗可在12周内提供高水平的保护，这为英国政府推迟第二次注射的策略提供了支持，以便更多人能进行疫苗接种。汉考克发表这番评论之前，牛津大学表示，有证据表明其疫苗能将病毒传播减少三分之二，并能预防严重疾病。这项研究尚未经过同行评议，但受到了英国官员的热烈欢迎，这些英国官员正面临压力，证明其推迟第二次注射的决定是合理的。查尔斯·德·莱德斯马，伦敦报道。
