利用生物制品进行预防接种要求有较高的预防接种率,以保证形成人群免疫屏障,达到控制某些传染病的发生与流行的目的。接种率是经常用来评价和衡量预防接种质量的重要指标,进行接种率调查已被列为常规工作。但是,在使用接种率对预防接种质量进行评价时只有运用正确的调查方法,才能得出与实际相符的科学结论。接种率这一概念,与WHO提出的覆盖率具有相似的含义。实际上疫苗覆盖率 The use of biological products for vaccination requires a higher vaccination rate in order to ensure the formation of the population immune barrier, to control the occurrence and prevalence of certain infectious diseases. Vaccination rates are often used to evaluate and measure the quality of vaccination, an important indicator of the vaccination rate survey has been classified as routine work. However, when using vaccination rates to evaluate the quality of vaccination, only the correct investigation method can be used to arrive at a scientific conclusion that is consistent with the actual situation. The concept of inoculation rates has a similar meaning to that proposed by the WHO. In fact the vaccine coverage
