US may cut vaccine doses
美考慮將疫苗劑量減半
The US government is considering giving some people half the dose of Moderna's COVID-19 vaccine in order to speed vaccinations, a federal official said on Sunday.
一位聯邦政府官員1月3日表示，美國政府正在考慮將莫德納公司研發的新冠疫苗每針劑量減半，以加快疫苗接種速度。
Moncef Slaoui, head of Operation Warp Speed, the federal vaccine program, said on CBS' "Face the Nation" that officials were in talks with Moderna and the Food and Drug Administration about the idea.
聯邦新冠疫苗項目曲速行動的負責人蒙塞夫·斯拉維在接受美國哥倫比亞廣播公司《面向全國》節目採訪時表示，聯邦官員正在與莫德納公司、美國食品和藥物管理局就上述設想進行溝通。
Moderna's vaccine requires two injections.
莫德納公司的疫苗需要注射兩次。
"We know that for the Moderna vaccine, giving half of the dose to people between the ages of 18 and 55, two doses, half the dose, which means exactly achieving the objective of immunizing double the number of people with the doses we have," Slaoui said. "We know it induces identical immune response" to the full dose, he added.
斯拉維説：“給18歲到55歲之間的人羣注射一半劑量的莫德納疫苗，注射兩劑，這樣可以在現有疫苗存量情況下讓接種人數增加一倍。”他還説，這樣做與注射全部劑量產生的免疫反應差不多。
Moderna and the FDA could not immediately be reached for comment.
目前莫德納公司和美國食品和藥物管理局對此沒有發表評論。
