才23%！南非研究显示辉瑞疫苗对奥密克戎有效性大幅下降

华尔街见闻2021-12-12

今日，据彭博社报道，南非实验室最新研究显示，接种两剂辉瑞新冠疫苗对预防奥密克戎有症状感染的有效性只有22.5%，但仍可防止重症。此前，南非非洲健康研究所在本周二发布了测试两剂辉瑞疫苗的研究数据。这项研究分析了12名参与者的血浆样本，南非研究人员发现，与感染初代新冠病毒患者体内抗体浓度水平相比，感染奥密克戎患者体内的中和抗体浓度水平下降了约40倍。该实验室的研究负责人 Alex Sigal在周五...

这不就是一个礼拜前的新闻了么？12个人的sample size…Pfizer CEO也说了booster能加强多少倍的抵抗力..疫苗过度有效，说明不用再打了…预期收益会降低…疫苗效果不大，会需要更多和frequent的 booster…只要疫苗的防重症率高，后面就真和流感一样了…就是打了也一样得，不会重症，口服药治疗 … Paxlovid的apporval和治愈率非常关键. $辉瑞(PFE)$是一直股价被压制的龙头股…
