US may cut vaccine doses
美考虑将疫苗剂量减半
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.
一位联邦政府官员1月3日表示，美国政府正在考虑将莫德纳公司研发的新冠疫苗每针剂量减半，以加快疫苗接种速度。
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.
联邦新冠疫苗项目曲速行动的负责人蒙塞夫·斯拉维在接受美国哥伦比亚广播公司《面向全国》节目采访时表示，联邦官员正在与莫德纳公司、美国食品和药物管理局就上述设想进行沟通。
Moderna's vaccine requires two injections.
莫德纳公司的疫苗需要注射两次。
"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.
斯拉维说：“给18岁到55岁之间的人群注射一半剂量的莫德纳疫苗，注射两剂，这样可以在现有疫苗存量情况下让接种人数增加一倍。”他还说，这样做与注射全部剂量产生的免疫反应差不多。
Moderna and the FDA could not immediately be reached for comment.
目前莫德纳公司和美国食品和药物管理局对此没有发表评论。
