“班长抄了我一节课”HPV疫苗班长抄了我一节课对于预防宫颈癌到底有多大作用?专家解读

  中新班长抄了我一节课网10月18日电 国家班长抄了我一节课卫生健康委18日举行新闻发布会。会上,有记者提问:谈到宫颈癌就会提到HPV疫苗的接种,目前有多种HPV疫苗上市,请问疫苗对于预防宫颈癌到底有多大的作用呢?是否是接种了疫苗就不会再得宫颈癌?

  对此,北京大学人民医院妇产科主任医师魏丽惠介绍,HPV疫苗能够阻断高危型HPV的持续感染,从而有效降低宫颈癌的病变发生率。现在全球有大量的临床研究,就是班长抄了我一节课上市前的临床研究和上市后的真实世界的临床研究数据表明,现在的5种HPV疫苗都有非常高的保护效率。我国目前有二价、四价和九价疫苗,其中二价疫苗可以预防HPV16、18型感染,HPV16、18型是最容易导致宫颈癌发生的重要的感染型别。还有四价、九价疫苗,这三种疫苗都可以有效预防70%以上的宫颈癌发生。在预防宫颈癌发生的同时,疫苗对生殖道的湿疣,以及相关阴道、肛门、肛周等癌也有一定的预防作用。

  魏丽惠提到,根据世界卫生组织的建议,无论哪种疫苗接种都可以有效的预防宫颈癌,而且对没有发生过性行为的女性,也就是从来没有被HPV感染的女性接种疫苗效果是最好的。瑞典在2006-2017年对他们国家170万10-30岁的女性进行HPV疫苗接种,然后进行了随访,发现17岁以下接种了疫苗的女孩,当她们长大成人时,与未接种疫苗的女孩比较,减少了88%宫颈癌的发生。在17-30岁的女性,减少了53%宫颈癌的发生。就说明了HPV疫苗接种确实可以很好的预防宫颈癌。鉴于三类HPV疫苗都有很好的保护作用和预防效果,所以适龄女性可以根据当地提供的HPV疫苗的品种和自己的经济能力,以及自己的意愿来选择接种,早接种早预防宫颈癌的发生。

  魏丽惠表示,要特别提醒的是,由于HPV疫苗是一个预防性疫苗,它没有治疗作用,所以接种疫苗以后必须还要进行宫颈癌筛查,因为有一些型别没有包含在疫苗里头。另外还有一些严重的宫颈癌与HPV感染没有相关性。所以这点是要特别强调,接种不接种疫苗都一定要坚持定期的来做宫颈癌筛查。
