这种候选疫苗是正在研发的150多种新冠肺炎疫苗中最先进的一种。新冠肺炎已经在全球夺去了60多万人的生命,并给经济造成严重影响。
The vaccine utilizes the chemical messenger RNA to instruct cells to make proteins that mimic the surface of the coronavirus, which the immune system sees as a foreign invader and mounts an attack. Although the technology has been around for years, there has never been an approved messenger RNA (mRNA)vaccine.
这种疫苗利用化学信使RNA来命令细胞制造模仿冠状病毒表面的蛋白质,免疫系统将其视为外来入侵者并发动攻击。尽管这项技术已经存在多年,但还没有一种被批准的信使RNA疫苗。
The Trump administration has agreed to spend billions of dollars for the development and procurement of potential vaccines under its Operation Warp Speed program.
特朗普政府已经同意花费数十亿美元通过“曲速行动”项目来研发和采购潜在的疫苗。
The aim is to produce vaccines that can end the pandemic by protecting billions of people from infection or severe illness, and governments have signed deals with drugmakers to secure supplies of various candidates. Whether any will succeed remains far from clear.
这样做的目的是生产疫苗,保护数十亿人免受感染或患上严重疾病,从而结束疫情。多国政府已与制药商签署协议,以确保各种候选疫苗的供应。然而是否有哪种疫苗会成功还远不清楚。
