南通开发区2005—2006年度脊灰疫苗强化免疫活动效果评价

Evaluation of the Aggrandized Immunization of Polio Vaccine in Nantong Economic and Technological Development Zone during 2005—2006

目的了解南通市开发区2005—2006年度脊髓灰质炎疫苗强化免疫活动效果,为今后计划免疫工作提供依据。方法按照脊髓灰质炎强化免疫活动实施方案于2005年12月5、6日和2006年1月5、6日在全区范围内开展了2轮脊灰疫苗强化免疫活动,并在每轮服苗结束后进行了现场快速评估。结果2轮报告接种率分别为98.44%、98.57%,均达到95%以上的目标。通过零剂次儿童分析,发现零剂次儿童主要集中分布在<1岁组儿童(96.08%),并且流动儿童中零剂次免疫儿童占全部零剂次免疫儿童的75.00%。现场快速评估调查外来居住<3月龄的流动儿童接种率分别只有58.82%和43.75%,且现场快速评估接种率低于报告接种率。结论2轮强化免疫活动取得了较好的成绩,但消除脊髓灰质炎是一项长期而艰巨的任务,需要不懈的努力。零剂次儿童是强化免疫的重点。流动儿童接种率偏低,今后应继续加强儿童预防接种工作,特别是流动儿童预防接种工作。

[ Objective ] To understand the effect of aggrandized immunization of polio vaccine in Nantong Economic and Technologi- cal Development Zone during 2005--2006 and provide evidence for the future planned immunization work. [ Methods ] According to the implementation plan of aggrandized immunization of polio vaccine, two rounds of polio vaccine immunization activities were carried out in December 5th and 6th of 2005 and January 5th and 6th 2006; on-site rapid assessment was carried out after each immunization activity. [ Results] The two reported vaccination rates were 98.44% and 98.57% respectively, both of which reached the goal of 95% ; the zero-dose children analysis found that the zero-dose children were mainly concentrated in the group aged under 1-year- old { 96.08% ）, 75.00% of which were floating children; the on-site rapid assessment found that the vaccination rates were only 58. 82% and 43.75 % among the floating children under the age of 3 months; the vaccination rate got on-site was lower than that reported. [ Conclusion] The two rounds of aggrandized immunization of polio vaccine was proved to be successful, but to eliminate polio is a long-term and arduous task requiring unremitting efforts; the zero-dose children is the emphasis of the aggrandized immunization; the vaccination rate is low among the floating children; prevention and vaccination work should be improved among the children, especially among the floating children.
