The study aimed to assess the capacity of AEFI surveillance during vaccination campaigns with the new conjugate meningitis vaccine (MenAfrivac). A systematic review of studies on MenAfrivac™ published in English during 2001-2016 was done.AEFIs incidence (I) was estimated and compared between MenAfrivac™ clinical trials and immunization campaigns using incidence difference (Id). Nine studies were included with an overall local AEFI I of 11,496/100,000 doses administered per week in clinical trials and 0.72/100,000 doses in immunization campaigns. An Id of 11,497.92 [11,497.91-11,497.93] and 17,243.20 [17,241.80-17,245.90] per 100,000 doses administered per week for overall local and systemic AEFI, respectively, were observed with highest from clinical trials. The incidence of AEFIs after MenAfrivac™ vaccination was far lower in campaigns than in clinical trial studies. Current capacity of AEFI surveillance during vaccination campaigns requires extensive re-assessment of its structure and capacity.
该研究旨在评估在使用新型结合型脑膜炎疫苗(MenAfrivac)开展疫苗接种活动期间的疑似预防接种异常反应(AEFI)监测能力。对2001年至2016年期间以英文发表的关于MenAfrivac™的研究进行了系统评价。通过发病率差异(Id)对MenAfrivac™临床试验和免疫接种活动中的AEFI发病率(I)进行了估计和比较。纳入了9项研究,临床试验中总体局部AEFI发病率为每周每10万剂次接种11496例,免疫接种活动中为每10万剂次接种0.72例。观察到总体局部和全身AEFI每周每10万剂次接种的发病率差异分别为11497.92[11497.91 - 11497.93]和17243.20[17241.80 - 17245.90],临床试验中的发病率差异最高。MenAfrivac™疫苗接种后的AEFI发病率在免疫接种活动中远低于临床试验研究。当前疫苗接种活动期间AEFI监测的能力需要对其结构和能力进行广泛的重新评估。
