Lancet:多元B群脑膜炎球菌疫苗(4CMenB)效果评价

2016-10-30 MedSci MedSci原创

2015年9月,英国成为第一个引入多元B群脑膜炎球菌(MenB)疫苗(4CMenB, Bexsero)的国家,建立公立国家免疫计划。在婴儿2个月和4个月时,提供两剂量的疫苗接种。4CMenB可以对抗73–88%的MenB。我们的目的是,评估4CMenB的有效性,以及该疫苗对疫苗合格的婴儿的影响。英国公共卫生部门(PHE)增强脑膜炎球菌疾病监测(结合临床、公共卫生和实验室报告)。实验室确诊脑膜炎球菌

2015年9月,英国成为第一个引入多元B群脑膜炎球菌(MenB)疫苗(4CMenB, Bexsero)的国家,建立公立国家免疫计划。在婴儿2个月和4个月时,提供两剂量的疫苗接种。4CMenB可以对抗73–88%的MenB。我们的目的是,评估4CMenB的有效性,以及该疫苗对疫苗合格的婴儿的影响。

英国公共卫生部门(PHE)增强脑膜炎球菌疾病监测(结合临床、公共卫生和实验室报告)。实验室确诊脑膜炎球菌病的患者由PHE当地健康保护小组、全科医生和医院临床医生进行随访,收集人口统计数据、疫苗接种史、临床表现和预后。对于2015年9月1日到2016年6月30日诊断的案例,使用筛选方法评估疫苗的有效性。比较疫苗合格的婴儿中MenB案例数与过去4年同等队列中的案例数,以及疫苗不合格的婴儿中的案例数,以评估疫苗的影响。

疫苗合格的婴儿中4CMenB覆盖率较高,一剂量达到95·5%,两剂量达到88·6%。两剂量疫苗对所有MenB的有效率为82·9%(95% CI 24·1–95·2),对覆盖率为88%的MenB株的有效率为94·2%。与疫苗接种前的时期相比,疫苗合格队列的MenB案例降低50%(37例 vs 74例;IRR 0·50 [95% CI 0·36–0·71]; p=0·0001),与疫苗不合格的队列比较,看到类似趋势。

两剂量4CMenB对婴幼儿MenB疾病的预防非常有效。目前国家正在继续监控,以调查该计划的长期影响,以确保疫苗能对抗这种致命的感染。
