路透社称,透露这一消息的是美国疫苗和药物攻关计划“曲速行动”的首席顾问蒙塞夫•斯拉维。他在接受美国哥伦比亚广播公司(CBS)《面对国家》节目采访时说,美政府官员们正与美国生物技术企业莫德纳公司和美国食品和药物管理局就上述想法进行沟通。报道提到,莫德纳的疫苗需要对接种者进行两次注射。

斯拉维说,“我们知道,对于莫德纳疫苗来说,给18岁至55岁之间的人注射一半剂量,分两次注射,都是一半剂量,恰好意味着可以在现有疫苗存量情况下让接种人数增加一倍的目标。”他还说,“我们知道,(注射一半剂量)可以与注射全部剂量产生出完全相同的免疫反应”。
报道称,斯拉维还对疫苗接种将继续加速持乐观态度。他拒绝了有关官方应优先给更多人注射一剂疫苗而不为第二次注射保留剂量的建议,并称将莫德纳疫苗剂量减半是“一种基于事实和数据的更负责任的方法”。
