Moderna认为其疫苗将至少一年预防冠状病毒

Biotechnology company Moderna believes its vaccine should protect people against 新冠肺炎 for at least a year, 一位高级官员周一告诉投资者.

Our expectation is that the vaccination should last you at least a year,” Moderna’s chief medical officer Tal Zaks told the JP Morgan 39th Annual Healthcare Conference.
Both Moderna’s and Pfizer/BioNTech’s coronavirus vaccines have won emergency use authorization from the US Food and Drug Administration.
Zaks said the company will have to test people to see if adding a third dosea boostmight extend protection. 目前, the vaccine is given as two doses about a month apart. Because both vaccines were only invented within the past year, no one knows how long they’ll protect people.
We’ll have to boost people to see how well the boost works,” Zaks said. “We think there is an opportunity to boost, especially the ones at high risk, should you need it.
