Ｒ值 (某疫苗接种数与另一疫苗接种数的比值 )与Ｄ值 (某疫苗实际接种率与估计接种率之差 )是评估接种率的常用指标。在实际应用中 ,我们发现Ｒ值与Ｄ值受出生率与儿童流动情况两大因素的影响。1接种率评估的常用指标1 1Ｒ值所谓Ｒ值 ,是通过比较各种疫苗间的应种人数来判断报
The R value (the ratio of the number of vaccinations to another vaccination) to the value of D (the difference between the actual vaccination rate and the estimated vaccination rate) is a common indicator for evaluating the vaccination rate. In practice, we found that R and D values are influenced by two major factors: birth rate and child mobility. 1 inoculation rate of commonly used indicators of evaluation 1 1R value The so-called R value is determined by comparing the number of vaccines among various vaccines to judge
