辉瑞宣布其新冠疫苗有效性高达90%

A vaccine has been shown to be more than 90% effective in preventing Covid-19. That's good news right? But it sadly doesn't mean we can get the vaccine tomorrow. This is a preliminary analysis from a phase three trial, and more evidence is needed about how safe and effective this vaccine is, and then regulators need to be convinced that it can meet quality standards before it can be given to more people. But before we get too carried away, we really have to be careful about safety and scale around the vaccine. So whilst we can go with confidence, I don't think we're seeing any return to normal by Christmas. But the companies behind the vaccine- that's Pfizer and BioNTech- they're going to apply for emergency approval to use the vaccine by the end of November. We'll do our best, we've been working day and night. The clock never stops in our labs or offices so we'll keep on with that momentum.

经证实,有一种疫苗在预防新冠肺炎上的有效性超过90%。这是个好消息,对吧?但遗憾的是,这并不意味着我们明天就能够接种疫苗。这是针对第三阶段试验的初步分析,我们需要更多的证据来证明这种疫苗的安全性和有效性,还要说服监管机构疫苗能够达到质量标准,然后才能给更多的人注射。在忘乎所以之前,我们真的必须要注意疫苗的安全性和规模。尽管我们满怀自信,但我并不觉得在圣诞节之前能够恢复正常。但研制疫苗的辉瑞公司和BioNTech生物技术公司将申请紧急批准,争取在11底之前获批使用疫苗。我们会夜以继日的工作,尽力而为。实验室或办公室里的时钟不停,我们也将继续保持我们的工作势头,永不停歇。

This vaccine will need to be given in two doses around three weeks apart. But storing it is going to be a big challenge, it needs to be kept in ultra cold conditions at around -80℃, that's a big challenge. But the companies believe they can supply 50 million doses by the end of this year and around 1.3 billion by the end of 2021. It's important to say this is not the only Covid-19 vaccine currently in development. They are around a dozen at the same stage of testing and we could have others soon. There's a kind of tendency that we… when we get excited about these vaccines is to think about vaccines as a sort of silver bullet and this cannot replace just the time and tested methods of track and trace, monitoring the outbreak, changing our behavior. So extremely exciting, very hopeful but let's not take our eye off the ball of the very basics of how we respond to health crises.

这种疫苗需要分两次注射,间隔大约三周。但疫苗的储存也将是一个很大的挑战。它需要储存在-80℃的超低温条件下,任务艰巨。但研制疫苗的公司相信,他们到今年年底将能够供应5千万剂疫苗,到2021年年底将供应大约13亿剂疫苗。重要的是,这并不是目前唯一一种正在研发的新冠肺炎疫苗。有大约十几种疫苗正处于相同测试阶段,我们很快也会有其他疫苗问世。现在存在着一种趋势,我们对于这些疫苗兴奋不已,我们将这些疫苗视为灵丹妙药,但疫苗不能取代历经时间和经过检验的追踪方法,不能检测疫情,也不能改变我们的应对行为。所以尽管我们非常激动,而且满怀希望,但不要忽视卫生危机的基本应对方式。
