要避免计划免疫工作出现高接种率、高发病率的“二高”现象,关键在于提高有效接种率和建立高效信息系统。特别是象宜黄县这样的山区,由于居民居住分散,村组交通不便,做到这一点显得尤为困难而必要。笔者认为:急需建立这样一种应用模式——将计划免疫工作总体程序,按照严格的时空概念加以分解和组合,落实于农村计划免疫实施全过程,以建立稳固的免疫屏障。为此,我 To avoid the “second highest” phenomenon of high vaccination rate and high morbidity in immunization work, the key is to increase the effective vaccination rate and establish an efficient information system. Especially in the mountainous areas like Yihuang County, it is particularly difficult and necessary to do this because residents are scattered and the transportation of villages is inconvenient. The author believes that urgently need to establish such an application model - the overall program of immunization work plan, according to a strict space-time concept to be decomposed and combined, implemented in the entire process of implementation of rural plan immunization, in order to establish a solid immune barrier.
