目的了解洪泽县1~7岁人群水痘疫苗接种情况,为进一步提高水痘疫苗接种率和控制水痘疫情提供依据。方法通过免疫规划信息系统对洪泽县1~7岁儿童的水痘疫苗接种史进行描述性分析。结果共调查23 318名儿童,水痘疫苗接种率为59.80%(47.83%~66.48%),各年龄组之间儿童水痘疫苗接种率差异有统计学意义(χ2=3616.681,P<0.01),4岁组儿童接种率最高,为66.48%。本地与流动接儿童种率分别为58.65%和64.10%,流动儿童接种率高于本地儿童,差异有统计学意义(χ2=506.500,P<0.01)。结论洪泽县水痘疫苗接种率水平较低,需加强7岁以下儿童水痘疫苗接种宣传,提高接种率,控制托幼机构和学校水痘疫情。
Objective To understand the situation of chickenpox vaccination in 1 ~ 7 years old population in Hongze County and provide the basis for further increasing the rate of chickenpox vaccination and controlling the epidemic of chickenpox. Methods The immunization planning information system was used to describe the history of varicella vaccination among children aged 1 ~ 7 in Hongze County. Results A total of 23 318 children were investigated. The vaccination rate of chickenpox was 59.80% (47.83% ~ 66.48%). There was significant difference in the vaccination rate of children with chickenpox among all age groups (χ2 = 3616.681, P <0.01) The highest vaccination rate was 66.48%. The prevalence rates of local and migrant children were 58.65% and 64.10% respectively. The vaccination rate of migrant children was higher than that of local children (χ2 = 506.500, P <0.01). Conclusions The level of varicella vaccination in Hongze County is low. It is necessary to strengthen the publicity of varicella vaccination in children under 7 years of age, increase the vaccination rate and control the epidemic of chickenpox in kindergartens and schools.
