在一片悲伤情绪笼罩下的网络世界，今天来一点点正能量消息！全世界第一支新冠肺炎疫苗，今天（2020年3月16日）打出了第一针，而接受疫苗的是一位已经两个孩子的中年妈妈，为她的勇气点赞。
在西雅图“凯撒医疗集团华盛顿健康研究中心”(Kaiser Permanente Washington Health Research Institute)43岁的Jennifer Haller成为了第一个接种疫苗的人。
受测者将注射不同剂量的疫苗，他们不会因此而感染，原因在疫苗本身不含新冠病毒。实验的目标纯粹在检查看疫苗不会出现令人忧心的副作用，为接下来更大型测试铺路。
此次疫苗是NIH和Moderna公司联合开发的，Moderna公司曾在2018年创下美国最大生物医疗公司 IPO 纪录，是全球mRNA巨头之一。
3月5日， Moderna宣布，美国食品药品监督管理局（FDA）已完成对该公司研制的新型冠状病毒mRNA疫苗——“mRNA-1273”的审查，批准其进入临床试验。
在FDA批准“mRNA-1273”疫苗进入临床试验后，Moderna公司开始招募45名健康志愿者进行药物测试。
很快45人就到位，目前预期具体结果或将于7月或8月宣布。
截至目前，新冠肺炎治疗仍没有特效药或者疫苗出现。

Coronavirus: US volunteers test first vaccine
By Michelle RobertsHealth editor, BBC News online
The first human trial of a vaccine to protect against pandemic coronavirus has started in the US.
Four patients received the jab at the Kaiser Permanente research facility in Seattle, Washington, reports the Associated Press news agency.
The vaccine cannot cause Covid-19 but contains a harmless genetic code copied from the virus that causes the disease.
Experts say it will still take many months to know if this vaccine, or others also in research, will work.
The first person to get the jab on Monday was a 43-year-old mother-of-two from Seattle.
"This is an amazing opportunity for me to do something," Jennifer Haller told AP.
Scientists around the world are fast-tracking research.
And this first human trial, funded by the National Institutes of Health, sidesteps a check that would normally be conducted - making sure the vaccine can trigger an immune response in animals.
But the biotechnology company behind the work, Moderna Therapeutics, says the vaccine has been made using a tried and tested process.
Dr John Tregoning, an expert in infectious diseases at Imperial College London, UK, said: "This vaccine uses pre-existing technology.
"It's been made to a very high standard, using things that we know are safe to use in people and those taking part in the trial will be very closely monitored.
"Yes, this is very fast - but it is a race against the virus, not against each other as scientists, and it's being done for the benefit of humanity."
Typical vaccines for viruses, such as measles, are made from a weakened or killed virus.
But the mRNA-1273 vaccine is not made from the virus that causes Covid-19.
Instead, it includes a short segment of genetic code copied from the virus that scientists have been able to make in a laboratory.
This will hopefully prime the body's own immune system to fight off the real infection.
The volunteers were being given different doses of the experimental vaccine.
They will each be given two jabs in total, 28 days apart, into the upper arm muscle.
But even if these initial safety tests go well, it could still take up to 18 months for any potential vaccine to become available for the public.
