目的:通过分析2013年杭州市第一类疫苗损耗系数,了解第一类疫苗损耗程度,以便科学制定疫苗使用计划,规范疫苗管理。方法:运用浙江省免疫规划信息管理系统,对2013年杭州市一类疫苗损耗系数进行分析。结果:2013年杭州市使用的一类疫苗共11种,损耗系数最高的为卡介苗2.12,其次为白破疫苗1.55,A群流脑疫苗1.44,脊髓灰质炎减毒活疫苗糖丸1.24,甲肝减毒活疫苗和麻腮风疫苗的损耗系数均为1.01,麻风疫苗、无细胞百白破疫苗、A+C群流脑疫苗、乙脑减毒活疫苗与10ug乙肝疫苗的损耗系数均为1.0。将损耗系数在不同地区作比较,脊髓灰质炎减毒活疫苗糖丸的损耗系数在老城区、新城区和郊县市分别为1.23、1.23和1.28,卡介苗的损耗系数分别为2.09、2.16和2.08,白破疫苗的损耗系数分别为1.36、1.62、1.70,A群流脑疫苗的损耗系数分别为1.39、1.42和1.56,其余一类疫苗在3个地区的损耗系数均为1.0。不同地区之间的一类疫苗损耗系数均未显示存在统计学差异。结论:2013年杭州市一类疫苗损耗系数较低,一类疫苗损耗程度较小。
OBJECTIVE: To understand the extent of the first type of vaccine loss by analyzing the first type vaccine loss factor in Hangzhou in 2013 in order to scientifically formulate a vaccine use plan and regulate vaccine administration. Methods: Using the immunization planning information management system in Zhejiang Province, the first-class vaccine loss coefficient in Hangzhou in 2013 was analyzed. Results: A total of 11 kinds of vaccines were used in Hangzhou in 2013 with the highest loss coefficient of 2.12 BCG, followed by Baipai vaccine 1.55, A group meningitis vaccine 1.44, poliovirus vaccine 1.24, The loss coefficients of the live vaccine and the mumps vaccine were both 1.01. The loss coefficients of leprosy vaccine, cell-free diphtheria-pertussis vaccine, A + C meningitis vaccine, live attenuated JE vaccine and 10ug hepatitis B vaccine were both 1.0. The loss coefficients were compared in different regions. The loss coefficients of live attenuated polio vaccine were 1.23,1.23 and 1.28 respectively in old city, new urban area and suburban counties, and the loss coefficients of BCG were 2.09, 2.16 and 2.08 , The loss factor of Baibu vaccine was 1.36,1.62,1.70 respectively, the loss coefficient of meningitis A group vaccine were 1.39,1.42 and 1.56, respectively. The loss coefficients of the remaining vaccine in three regions were 1.0. There was no statistical difference in a class of vaccine loss factors between regions. Conclusion: In 2013, the first-class vaccines had a lower loss coefficient and a lower degree of vaccine loss.
