阿斯利康的COVID-19候选疫苗:有效率达70%

2020-11-23 MedSci原创 MedSci原创

该结果意味着黑猩猩腺病毒改良版的新冠疫苗达到了试验的主要终点。

在英国COV002 II/III期试验和巴西COV003 III期研究的中期分析中显示,阿斯利康和牛津大学的新冠病毒COVID-19候选疫苗AZD1222平均功效达70%。

AZ在声明中表示,该结果意味着黑猩猩腺病毒改良版的新冠疫苗达到了试验的主要终点,表明其“在预防COVID-19方面非常有效”。

平均功效率来自两种不同的给药方案,其中一种表现出更好的效果。第一种剂量方案:首先以半剂量使用AZD1222,然后在至少一个月后以全剂量使用,显示出90%的疫苗效力。第二种方案:两次均以全剂量使用,间隔至少一个月,显示出62%的功效。

同样在本月,辉瑞/BioNTech和Moderna分别公布了各自COVID-19疫苗III期试验的结果。

辉瑞/BioNTech的mRNA疫苗BNT162b2功效为95%,而Moderna的候选mRNA-127的功效为94.5%。
