　　World Health Organization (WHO) chief scientist Soumya Swaminathan said Monday that herd immunity to coronavirus would not be achieved in 2021, despite the growing availability of vaccines.

　　世界卫生组织的首席科学家苏米娅·斯瓦米纳坦周一（1月11日）表示，即使疫苗产量不断增加，也不可能在2021年实现对新冠病毒的群体免疫。

　　Mitigating factors to herd immunity include limited access to vaccines in developing countries, skepticism over vaccination, and the potential for virus mutations, according to health experts.

　　卫生专家指出，阻止群体免疫实现的因素包括发展中国家获得疫苗的能力有限、民众对接种疫苗的质疑以及病毒变异的可能性。

　　A growing number of countries around the world, including the United States, the United Kingdom, Singapore, Germany and other European Union countries, are in the first stages of mass-vaccination campaigns.

　　全世界越来越多的国家都开始了第一阶段的大规模疫苗接种，包括美国、英国、新加坡、德国和其他欧盟国家。

　　Herd immunity occurs when enough people in a population have immunity to an infection so that it prevents the disease from spreading.

　　当足够多的人口对一种传染病免疫，从而防止了疫病传播，群体免疫就实现了。

　　"We are not going to achieve any levels of population immunity or herd immunity in 2021," Swaminathan told a briefing, while emphasizing that measures like physical distancing, hand washing and mask wearing continue to be necessary in containing COVID's spread for the rest of the year.

　　斯瓦米纳坦在新闻发布会上说：“我们不可能在2021年实现任何程度的人群免疫或群体免疫。”同时她还强调，继续推行保持距离、勤洗手、佩戴口罩等措施对于在接下来的这一年控制新冠疫情传播很有必要。

　　However, Swaminathan commended the "incredible progress" made by vaccine researchers to develop several safe and effective vaccines at unprecedented speed. Countries are currently administering vaccines developed by BioNTech-Pfizer, Oxford University/AstraZeneca and Moderna.

　　不过，斯瓦米纳坦称赞了疫苗研究人员取得的“惊人进展”，他们以史无前例的速度研发出了数种安全有效的疫苗。目前多个国家正在接种生物新技术/辉瑞、牛津/阿斯利康和莫德纳公司研发的疫苗。
