阿联酋目前已经接种了超过750万剂冠状病毒疫苗，其中大部分是国药集团的疫苗。

那么，它的有效性如何呢？对人体的保护可以持续多久？

///国药集团的疫苗对预防新冠有效吗？

阿联酋的测试表明，在31000名志愿者参加的第三阶段试验中，该疫苗的有效性为86%——在接收到更多数据之后，又将这一数字修正为79.34%。

专家表示，关键指标在于该疫苗是否可以保护人们免受严重的感染。

仍然没有证据表明有人在接种疫苗后患上严重疾病。

国家Covid-19临床管理委员会主席纳瓦尔·卡比博士说，在接种疫苗的人群中，没有人出现严重感染情况或者死亡。

她说，在接种两剂疫苗后依旧被感染的人中，大多仍然是无症状或只出现轻微症状的患者。

///国药集团的疫苗抵御新病毒株的效果如何？

2月份的一项研究显示，该型疫苗对南非变种新冠病毒的效果较差，但仍有效。

这是最令人担忧的变种之一，因为它更具传染性。

///疫苗提供的保护能持续多久？

阿联酋政府目前的估计表明，两剂疫苗可以提供4至6个月的免疫力保护。
