周二,疫苗概念股普涨。截至发稿,Moderna盘中涨超13%,截至发稿涨9%。BioNTech SE涨近6%,诺瓦瓦克斯医药、辉瑞涨2%。消息面上,据世界卫生组织公布,近期西非、中美洲和加勒比地区、东欧、西南欧和西亚部分国家新冠疫情呈上升趋势。同时,美国食品和药物管理局(FDA)宣布新的COVID-19疫苗增强剂指南。
根据最新报道,FDA计划要求对65岁以下健康成年人进行新的临床试验,以批准年度COVID-19增强剂注射。这一政策可能会限制今年秋季增强剂的使用范围,主要面向65岁以上老年人和高风险人群。尽管这可能会延迟更新疫苗的上市时间,但FDA官员表示,预计仍有1亿至2亿美国人有资格每年接种疫苗。
