扩大免疫规划(EPl)是一个使全球儿童都能得到预防六种传染病的免疫接种计划,仅在发展中国家这一计划每年就可挽救320万儿童的生命。儿童疫苗计划是一个在统一管理机构下协调产品开发、征募研制人员及赞助者的规划,它的最终目的是使人们认识到只有采用新疫苗和改良疫苗,才能使全球免疫规划达到最佳效果。高效疫苗的开发不仅能增强EPI的效力,节约资金,而且关系到CVI的成败。新疫苗的研制需要较大的投入,但资金来源是一个严重问题。对发展中国家,CVI将为它们筹集必要的资金。
EPI is an immunization program that enables children worldwide to prevent six infectious diseases and this program alone in developing countries can save 3.2 million children each year. The Children’s Vaccine Program is a program that coordinates product development, recruiting developers and sponsors under a unified management agency whose ultimate goal is to make people aware that the best results of global immunization programs can only be achieved with new and improved vaccines. The development of highly effective vaccines not only enhances the effectiveness of EPI, saves money, but also affects the success or failure of CVI. The development of a new vaccine requires a large investment, but the source of funding is a serious problem. For developing countries, CVI will raise the necessary funds for them.
