安徽智飞新冠疫苗要打三针的原理是什么(智飞三针)，

目前国内上市的多款新冠疫苗主要可分为三类，腺病毒载体疫苗只需要接种1针，灭活疫苗需要接种2针，而重组蛋白疫苗需要接种三针。而目前很多市民接种的安徽智飞新冠疫苗就是三剂次的，那安徽智飞新冠疫苗为什么要打三针呢？一起来了解看看吧。

安徽智飞新冠疫苗为什么要打三针

安徽智飞新冠疫苗是一种重组蛋白疫苗，这种疫苗的安全性是比较高的，有效率也非常的高。而之所以要接种三针，目的是使得免疫效果更加持久，接种之后的有效期是比较长的，可以达到两年。

该款疫苗技术原理和已经运用很成熟的乙肝CHO细胞疫苗类似。它采用基因工程技术，在CHO细胞内表达病原体抗原RBD蛋白，经过纯化加入氢氧化铝佐剂制成的疫苗。整个生产过程是蛋白表达和纯化的过程，没有活病毒参与，所以生产过程是安全的，也容易大规模生产。相比较之前大范围接种的灭活疫苗，这款重组蛋白疫苗需要接种三剂，在接种之后，绝大部分的受试者均没有不良反应，极少数受试者可有接种部位的疼痛、红晕或者硬结，基本1-3天内能够自愈，因此安全性是良好的。
