5月20日盘中,诺瓦瓦克斯医药(NVAX)股价大涨5.1%,引发市场关注。此次涨势或与美国食品和药物管理局(FDA)最新发布的COVID-19疫苗增强剂指南有关。
根据FDA的新指南,65岁以上的老年人和具有高风险因素的人群仍将有资格每年接种COVID-19疫苗增强剂。FDA预计,基于测量患者免疫反应的测试数据,将能够批准为这些群体提供增强剂。这一政策可能会使约1亿至2亿美国人有机会每年接受注射,这对诺瓦瓦克斯等疫苗制造商来说是一个巨大的市场机会。
值得注意的是,诺瓦瓦克斯的COVID-19疫苗已于上周获得FDA批准,使用范围限于老年人和12岁以上因疾病而面临风险的人群。这与FDA新指南所针对的人群高度吻合,可能使诺瓦瓦克斯在未来的疫苗市场中占据有利地位。尽管FDA对健康成年人的疫苗批准政策更为严格,但老年人和高风险群体仍然是COVID-19疫苗的主要目标人群,这可能是投资者看好诺瓦瓦克斯前景的原因之一。
