一项新研究发现，国药疫苗对Delta变体有效。

斯里兰卡一所大学的研究人员表示，在接受第二次注射后的两周内，282名志愿者中有超过95%的人产生了抗体。

他们说，81%的（接种国药疫苗的）人能够产生中和病毒的特异性抗体。

然而，研究人员表示，与20至39岁年龄组的人相比，60岁以上人群的抗体反应较低。

“老年人的血清转化率和免疫原性似乎较低，”研究人员在一篇尚未经过同行评审的论文中写道。

研究人员表示，虽然该疫苗对Delta的抵抗力特别好，但与原始毒株相比，其保护水平略低。

国药集团研发了两种疫苗。该小组测试了这家中国制药公司北京分部生产的疫苗，该疫苗已在阿联酋广泛使用。

美国一家医学杂志表示，这两种疫苗的保护力达到了72.8%和78.1%，这与国药集团此前宣布的结果基本一致。

今年在阿布扎比进行的一项研究发现，国药疫苗在减少感染者的住院率方面有 90%以上的效果。

阿布扎比公共卫生中心的研究发现，阿联酋境内接种第二剂疫苗的人群中，新感染 新冠病毒的比率显着下降。

研究表明，所有疫苗，包括高效的mRNA型——例如 Pfizer-BioNTech）对Delta变种的预防效果都略差。
