美传染病专家:强生疫苗有效率较低但仍有助抗疫
阿思达克 02-02 11:00
美媒报道,美国国家过敏和传染病研究所所长福奇(Anthony Fauci)表示,强生(JNJ.US)新冠疫苗有效率低於Moderna及辉瑞(PFE.US)疫苗,但在应对疫情上仍能起作用。他指最重要的是疫苗对严重疾病的预防比率仍然非常高,即使在变种病毒主导的南非。他亦表示,在现实角度,於试图令民众不必入院及预防死亡方面,强生疫苗仍有附加值作用。

强生疫苗在预防温和至严重新冠个案的有效率为66%,低於辉瑞及Moderna的95%,在美国测试的有效率为72%,在南非测试的有效率为57%。但在预防严重个案中仍有85%有效率,在注射後28天预防入院或死亡的比率更达100%。
