使用有效生物制品以提高易感者机体免疫力,可以有效地控制和消除相应传染病。因此,预防接种后监测一个地区传染病发生情况,可作为评价计划免疫工作质量的一个可靠指标,1984年5～12月我们参照世界卫生组织(WHO)扩大免疫规划(EPI)按容量比例的概率抽样方法,通过培训抽查了我省71个市、县的2130个抽样单位(城市为居委会街道、农村为区级乡村),12～24个月龄儿童14,863名,进行卡介苗(BCG)、脊髓灰质炎活疫苗(OPV)、麻疹活疫苗(MV)、百白破三联混合剂(DPT)、(简称为“四苗”一下同)考核调查,现报告如下。
The use of effective biological products to improve susceptibility to the body’s immune system, can effectively control and eliminate the corresponding infectious diseases. Therefore, monitoring the incidence of infectious diseases in a region after vaccination can be used as a reliable indicator to evaluate the quality of planned immunization work. From May to December 1984, we refer to the probability of EPI according to the capacity of the World Health Organization (WHO) Sampling method, 2130 sampling units in 71 cities and counties in Shaanxi Province were selected (14,863 children aged 12-24 months) from 2130 sampling units (streets of neighborhood committees and districts in rural areas) and BCG (poliomyelitis) OPV, MV, DPT (DPT), (referred to as “Si Miao” about the same) assessment survey, are as follows.
