Epidemics of meningococcal disease constitute a major public health challenge in Africa, affecting mostly the 24 countries of the meningitis belt. These epidemics led to a call for a call for a safe, effective and affordable conjugate vaccine against the major serogroup responsible for recent epidemics by leaders of the region.
This paper documents experiences with efforts at eliminating epidemic meningitis in the African Region.
The meningoccocal serogroup A conjugate vaccine was developed, licensed and offered to more than 235 million people through mass vaccination campaigns in 16 countries since 2010. Future plans include providing the vaccine to the remaining countries in the African Meningitis Belt and, to implement the vaccine into routine national infant immunization programme and to organise catch-up immunization campaigns every 5 years for unvaccinated <5 year-olds who had missed their routine vaccinations.
The success of the project is evidenced by the large declines in cases of group A meningococcal disease since 2010, with no cases reported in vaccinated persons across the 16 countries, reflecting the highly effective nature of the vaccine. The successful control of serogroup A meningococcal disease has highlighted the need to tackle other meningococcal serogroups through development of polyvalent conjugate vaccines with the aim of eliminating epidemics of meningococcal meningitis in the African region.
脑膜炎球菌病的流行是非洲面临的一项重大公共卫生挑战,主要影响脑膜炎带的24个国家。这些疫情促使该地区领导人呼吁研发一种安全、有效且价格可承受的结合疫苗,以应对导致近期疫情的主要血清群。
本文记录了非洲区域消除流行性脑膜炎工作的经验。
自2010年以来,A群脑膜炎球菌结合疫苗已研发、获批,并通过在16个国家开展的大规模疫苗接种活动,为超过2.35亿人接种。未来计划包括向非洲脑膜炎带的其他国家提供该疫苗,将其纳入国家常规婴儿免疫规划,并每5年为未接种常规疫苗的5岁以下未接种儿童组织补种活动。
自2010年以来,A群脑膜炎球菌病病例大幅下降,16个国家的接种人群中均未报告病例,这证明了该项目的成功,也反映出该疫苗的高效性。A群脑膜炎球菌病的成功防控凸显了通过研发多价结合疫苗应对其他脑膜炎球菌血清群的必要性,目标是消除非洲区域的脑膜炎球菌性脑膜炎疫情。
