新华社北京12月13日电（记者李恒、张泉）中国疾控中心免疫规划首席专家王华庆13日在国务院联防联控机制新闻发布会上介绍，新冠病毒疫苗应用以来，从目前监测到的情况来看，60岁及以上老年人接种后，不良反应总体报告发生率略低于60岁以下人群，严重的不良反应发生率和其他人群发生的情况也基本类似，在百万分之一以下。王华庆说，一些特殊体质的人群接种疫苗之后，会出现与接种无关的反应，包括一般反应和异常反应。不良反应当中绝大多数都属于一般反应，极少数的是异常反应。针对接种新冠病毒疫苗之后多久能产生抗体的问题，王华庆表示，一般接种疫苗之后，人体在一周到两周的时间产生抗体。如果要产生比较高水平的抗体，大概在全程免疫之后4周左右。 “加强免疫之后产生抗体的时间更快、更短，产生的抗体水平也更高。”王华庆说，这也进一步提示，没有完成疫苗接种的老年人要尽快接种疫苗，获得更好保护。【纠错】【责任编辑:薛涛】
