蒋健敏建议6月龄以上，没有禁忌症的人员，都需要每年接种流感疫苗，也有以下人员需要优先安排接种的： 第一类是重点人群，主要是60岁及以上的老年人，还有患慢性疾病的患者。这类人群免疫力较低，如果感染流感病毒以后，容易引发肺炎、心肌炎等严重的 并发症，而且还有可能加重原有的基础性疾病，所以要优先接种。其次，是6月龄以上的婴幼儿和儿童，婴幼儿的免疫系统尚未发育完善，如果感染流感疫 苗以后，也往往容易引发高热惊厥、肺炎、脑炎这些重症的风险，而且也有可能在托幼机构或者学校内引发聚集性疫情。 21世纪经济报道记者 贺佳雯 北京报道 2025年10月9日，国家卫生健康委召开新闻发布会，介绍时令节气与健康（寒露）有关情况，并答记者问。 会上，南方财经·21世纪经济报道记者提问：天气转凉，流感等呼吸道疾病逐渐进入高发季。不少人对流感疫苗存在困惑。流感疫苗为什么每年打？哪些人 需要优先打？得过流感后还需要打疫苗吗？ 浙江省疾控中心研究员蒋健敏回应，目前，预防传染病最经济有效的技术方法就是接种疫苗。关于流感疫苗，为什么每年都要接种呢？主要有两方面的原 因：一方面，流感病毒容易发生变异，每年流行株的型别都可能不一样。因此，我们国家会根 ...

国家卫生健康委今天举行新闻发布会，介绍时令节气与健康有关情况。浙江省疾控中心研究员蒋健敏介绍，目前，预防传染病最经济有效的技术方法是接种 疫苗。 建议6月龄以上且无禁忌证的人都需要每年接种流感疫苗，以下人群更要优先安排： 每年都要接种流感疫苗，主要有两方面原因： 流感病毒容易发生变异，每年流行的毒株可能都不一样。我国会根据全国流感监测数据，参考世界卫生组织每年发布的流感疫苗株推荐意见，调整当季流感 疫苗的组分，让疫苗能与当年流行株抗原性尽可能匹配。 接种流感疫苗后，体内的抗体水平会随着时间慢慢下降，所以，需要每年接种才能获得更好的防护效果。 哪些人需要优先接种疫苗 为什么每年都需要接种流感疫苗 这类人群接种疫苗不仅可以预防自身感染，还可以保护身边那些感染后容易出现重症的人群，所以要优先接种。 为什么得过流感还要打疫苗 得过流感也要打疫苗，主要有两方面原因： 一方面，流感病毒有多种型别，得过一次流感产生的抗体，只对这次感染的型别有用。 一类是重点人群，主要是60岁及以上的老年人、慢性病患者等，他们免疫功能较低，感染流感病毒后容易引发肺炎、心肌炎等严重并发症，或加重原有基础 疾病； 其次是6月龄以上婴幼儿和儿童， ...

眼下又到了流感疫苗接种季，每年通过接种流感疫苗可有效预防流感流行，减少重症发生。到底有几种疫苗可以接种？该如何接种？ 流感疫苗有几种类型？ 该如何接种？ 医务人员提示，每年接种流感疫苗是预防流感最有效的手段，可以显著降低接种者罹患流感和发生严重并发症的风险。今年我国共有三种流感病毒疫苗： 疫苗中的"价"，指疫苗可以预防的某种病原体的类型数，从数量上来说，四价流感疫苗比三价的可以多预防一种乙型流感病毒的亚型。 北京市丰台区大红门社区卫生服务中心预防保健科医师 刘美玲：我们对于6月龄到三周岁的孩子推荐使用裂解疫苗，三周岁到17周岁的人群，这三种疫苗都 可以使用，大于18周岁的人群，我们推荐使用裂解疫苗和亚单位疫苗。 医务人员表示，要把握好接种流感疫苗的时间，流感高发期一般在冬春季节，也就是11月到第二年的3月。考虑到疫苗接种到人体后，一般需要2周到4周时 间才能产生保护作用，最好在流感季开始之前（每年9月到11月之间）接种流感疫苗。 哪些人不适合接种鼻喷流感疫苗？ 流感病毒灭活（裂解）疫苗（三价/四价，注射） 流感病毒灭活（亚单位）疫苗（三价/四价，注射） 流感病毒减毒活疫苗（三价，鼻喷） "三价""四价"的区别 ...
