Hum Vaccin Immunother:4CMenB疫苗接种后免疫反应的持久性

2020-06-14 MedSci原创 MedSci原创

多组分脑膜炎球菌血清群B疫苗4CMenB已证明可有效预防婴儿的侵袭性MenB疾病和控制MenB爆发。尚未确定是否需要额外的加强剂量/定时。

多组分脑膜炎球菌血清群B疫苗4CMenB已证明可有效预防婴儿的侵袭性MenB疾病和控制MenB爆发。尚未确定是否需要额外的加强剂量/定时。

 

我们回顾了八项评估婴儿,儿童,青少年和年轻人的初次4CMenB疫苗接种后抗体持久性和增强作用的研究。

 

结果显示,在婴儿期初次接种后24-36个月,有76-100%的儿童维持了≥1疫苗抗原的假定的血清保护性hSBA滴度,而在生命的第二年初次接种后,则维持在84-100%。青春期初免后4年和7.5年,疫苗中的hSBA水平高于未接种疫苗的相似年龄人群。抗体对NHBA和NadA的持久性高于对PorA或fHbp的抗体。加强疫苗接种可引起强烈的记忆消除反应,证明4CMenB在不同年龄段的人均可有效引发。

 

这些数据可以为决策提供依据,以优化疫苗接种策略。
