云南省两市区脊髓灰质炎灭活疫苗接种情况调查

Inoculation Situation of Inactivated Polio Vaccine in Two Urban Areas in Yunnan Province

目的:分析云南省昆明市五华区及丽江市脊髓灰质炎疫苗(PV)接种情况及脊髓灰质炎灭活疫苗(IPV)在每个剂次中所占的比率及普及情况。方法:从两地疾病预防控制中心儿童免疫规划信息管理系统中收集2016年5月～2017年7月儿童PV接种数据,应用描述性流行病学方法进行分析。结果:2016年5月～2017年7月,五华区共接种PV 65 349剂,每一剂接种率均为99%以上,第1、2、3及4次剂IPV所占比率分别为86. 02%、33. 62%、26. 30%及20. 33%;丽江市共接种脊髓灰质炎疫苗21 962剂,每一剂次接种率均为99%以上,第1、2、3及4次剂IPV所占比率分别为39. 75%、7. 55%、8. 20%及0. 07%,使用IPV种类多为Sabin-IPV、Salk-IPV、DTa P-IPV/Hib,DTa P-IPV/Hib所占比率最高(62. 63%,χ~2=9 597. 6,P <0. 001);丽江市IPV相对单一,95%为免费Sabin-IPV,五华区IPV接种率明显高于丽江市(χ~2=22 614. 9,P <0. 001)。结论:昆明市五华区IPV接种率明显高于丽江市。

Objective:To investigate inoculation situation of the polio vaccine(PV)and the proportion of inactivated polio vaccine(IPV)in each dose in Wuhua District of Kunming City and Lijiang City,Yunnan Province.Methods:The PV and IPV vaccination data of children from May 2016 to July 2017 were collected from the information management system of the Children's Immunization Program of the two local disease prevention and control centers.The descriptive epidemiological methods were used for analyzing data.Results:There were 65 349 PV doses in Wuhua District,and the inoculation rate of each dose was over 99%,and the percentages of IPV in the first,second,third and fourth dose were 86.02.%,33.62%,26.30%and 20.33%,respectively.In Lijiang City,there were 21 962 PV doses in total,and the inoculation rate of each dose reached 99%or more,but the percentage of IPV in the first,second,third and fourth dose were 39.75%,7.55%,8.20%and 0.07%.In Wuhua District,the most commonly used IPV types are Sabin-IPV,Salk-IPV and DTaP-IPV/Hib,among them,DTaP-IPV/Hib reached 62.63%(χ^2=9 597.6,P<0.001).In Lijiang City,95%of IPV is free Sabin-IPV.IPV vaccination rate in Wuhua District is significantly higher than that in Lijiang City(χ^2=22 614.9,P<0.001).Conclusion:The IPV vaccination rate in Wuhua District of Kunming City is significantly higher than that in Lijiang City.
