中国工程院院士王军志:未发现病毒变异株对我国新冠疫苗保护率产生明显影响

2021-04-03 中国新闻网 中国新闻网

“目前,我们还没有发现新冠病毒的变异株对我国附条件上市的新冠疫苗的保护率产生明显的影响。”科研攻关组疫苗研发专班副组长、中国工程院院士王军志15日表示。

“目前,我们还没有发现新冠病毒的变异株对我国附条件上市的新冠疫苗的保护率产生明显的影响。”科研攻关组疫苗研发专班副组长、中国工程院院士王军志15日表示。

15日,国务院联防联控机制就推进新冠疫苗接种有关情况举行发布会。针对“目前国内已经获批附条件上市的几款疫苗在应对新冠病毒变异方面效果如何”一问,王军志作出如上表述。

王军志还称,研发企业针对当前收集到的国内外这几种变异株采用疫苗免疫血清进行交叉中和能力的测试和评估,最新一篇报道也没有发现灭活疫苗、重组蛋白疫苗对变异株,包括南非株的中和活性有明显下降,所以还要跟踪进行研究。

“我们对这个问题应该高度重视,病毒长期传播可能会产生多个突变的积累,积累到一定程度就会出现影响疫苗保护力的风险,这个风险是存在的。为有效应对病毒变异造成的影响,我们必须提前谋划和积极准备。”王军志表示。

王军志指出,有两个方面的工作非常重要,一方面密切监测,实时监测,发现后尽快收集,收集到以后进行测定,及时发现它对疫苗的影响。另一方面,加强疫苗的平台建设,通过五条技术路线的部署,我国已经建立了很强大的疫苗研发平台。

“我国同时积极研究新一代的疫苗,一旦出现我们担心的情况,病毒变异引起疫苗免疫效果消失或者大幅度降低的情况,能够在最短时间研发出针对变异株的疫苗,这是非常关键的。”王军志表示。

“整体上来说,我们要通过综合能力的提高,提升应对各种病毒变异株的能力,这是最重要的。”王军志称。
