Through its normative and public health leadership roles, the World Health Organization (WHO) plays a key role in the availability of vaccine products in low-and middle-income countries. The recent introduction of a new group A meningococcal conjugate vaccine, PsA-TT (MenAfriVac), in Africa exemplifies this process. WHO requires that any new vaccine to be introduced in countries for public health reasons and supplied through United Nations centralized mechanisms be licensed by the national regulatory agency (NRA) in the producing country, then prequalified and given a marketing authorization in the user countries.
PsA-TT was manufactured by the Serum Institute of India, Ltd (SIIL), which submitted a license application in April 2009 to the Drug Controller General of India (DCGI), the Indian NRA responsible for licensing vaccines. WHO encouraged the DCGI to establish a collaboration with Health Canada's Centre for Vaccine Evaluation for the review. Through this collaborative effort, registration was facilitated and in December 2009 an export license was granted to SIIL, which subsequently submitted an application for WHO prequalification.
Given the importance of the vaccine, WHO "fast tracked" the prequalification review, and after a detailed review and site visit, WHO prequalification was granted to PsA-TT in June 2010. Country use of the new vaccine could not occur until the vaccine was a registered product in each country seeking its use. WHO facilitated country reviews by conducting regulatory training exercises (in French and English) for country NRA staff, which used the PsA-TT registration as a case study.
PsA-TT was gradually registered in African countries as vaccine introduction proceeded. The regulatory pathway for this new group A meningococcal conjugate vaccine proved to be a useful training opportunity both in India and Africa, because the availability of the vaccine was a high African public health priority, as well as for WHO as a case study to facilitate registration of vaccines based on reliance on other regulatory bodies.
通过其规范和公共卫生领导作用,世界卫生组织(WHO)在低收入和中等收入国家疫苗产品的供应方面发挥着关键作用。最近在非洲引入的一种新型A群脑膜炎球菌结合疫苗,即PsA-TT(MenAfriVac),就是这一过程的例证。WHO要求,出于公共卫生原因在各国引入并通过联合国集中机制供应的任何新疫苗,须先获得生产国药管局(NRA)的许可,然后在使用国进行预认证并获得上市许可。
PsA-TT由印度血清研究所(SIIL)生产,该研究所于2009年4月向印度药品总监(DCGI)提交了许可申请,DCGI是负责疫苗许可的印度NRA。WHO鼓励DCGI与加拿大卫生部疫苗评估中心建立合作进行审评。通过这一合作努力,审评得以顺利进行,2009年12月SIIL获得了出口许可,随后提交了WHO预认证申请。
鉴于该疫苗的重要性,WHO对预认证审评进行了“快速通道”处理,经过详细审评和实地考察后,2010年6月PsA-TT获得了WHO预认证。在每个希望使用该新疫苗的国家将其注册为产品之前,该国无法使用该疫苗。WHO通过为各国NRA工作人员开展监管培训活动(用法语和英语)来推动各国审评,培训以PsA-TT注册为案例研究。
随着疫苗引入工作的推进,PsA-TT在非洲国家逐步注册。这种新型A群脑膜炎球菌结合疫苗的监管途径在印度和非洲都被证明是一次有益的培训机会,因为该疫苗的供应是非洲公共卫生的高度优先事项,同时对于WHO而言也是一个便于基于对其他监管机构的依赖来推动疫苗注册的案例研究。
