鼻喷疫苗能抵挡奥密克戎吗_热点头条，

如今，疫情防控措施放宽，感染新冠的人越来越多，许多人都希望可以接种第四针疫苗来加强免疫。最新消息，由厦门大学、香港大学和万泰生物联合研发的鼻喷流感病毒载体新冠肺炎疫苗获批紧急使用。那么，鼻喷疫苗能抵挡奥密克戎吗？下面来了解看看吧。

　　目前，奥密克戎毒株仍在全球广泛传播，感染人数持续增加。研发团队表示，鼻喷疫苗通过鼻腔喷注的形式进行接种，有效模拟了新冠病毒进入并感染机体的路径。从目前病毒变异的规律来看，奥密克戎及今后可能出现的变异株的传染速度势必会更快，把新冠病毒抵御在机体第一道防线之外尤为重要。

　　此外，该鼻喷疫苗通过鼻腔喷注的形式进行接种，接种禁忌症和偶合并发症更少。另外，该款疫苗在三期临床时侧重了对60岁以上老年人群和基础慢病人群的保护效果和安全性验证。

　　专家指出，新冠疫苗仍然是群体预防新冠最经济、最有效的手段，尤其在降低老年人感染新冠病毒后发生重症、危重症和死亡风险方面具有重要保护作用。为更快恢复到健康的生产、生活状态，未完成3剂疫苗接种的应尽快完成，已完成全程3剂灭活后6个月的重点人群可尽快前往社区接种新一轮的加强剂次。

　　以上就是鼻喷疫苗能抵挡奥密克戎吗介绍了。希望上述内容对大家有所帮助。

其他拓展知识
*:答:有一定的预防作用。研究结果显示,现有疫苗对奥密克戎变异株仍有一定保护效果,只是对其预防感染的能力有所下降,针对奥密克戎变异株,现有疫苗预防重症和死亡仍有效果,而接种...

*:◆如果原有疫苗所产生的中和抗体针对变异株活性大幅下降,就需要研发新疫苗; ◆如果对变异株仍具有很好的中和作用,则无需研发新疫苗。尽管奥密克戎毒株变异速度快,出现不同分支,但并不会针对每个...

*:但随着新型冠状病毒的不断变异,变异株的免疫逃逸能力逐渐增强,新型冠状病毒疫苗所能起到的预防作用相对减弱,尤其新型冠状病毒奥密克戎变异株的免疫逃逸能力比较强,所以吸入式...","subtitleWithAvatar":[{"text":"迟翔宇主任医师山东省立医院三甲发布时间:
