本文通过对南阳市９个县市的１４１１名７岁以下儿童血清中麻疹抗体水平的横断面抽查，经统计学处理分析后认为：麻疹疫苗的免疫接种是提高小年龄组抗体水平的主要途径。１岁年龄组至６岁年龄组的抗体限性者其ＧＷＴ存在逐年递减的情况，但和阳性率一样其间尤显著性差异。所以，７周岁儿童麻疹疫苗加强的主要意义还是在于增加补漏的免疫机会。各县市儿童麻疹抗体阳性者ＧＭＴ的差异反映出计免工作开展的不均衡。因此，尽可能准确地掌握儿童数，增加及时免疫机会，保证接种质量是目前进一步提高７岁以下儿童抗体水平，减少暴发点出现的关键。
In this paper, a cross-sectional survey of the serum levels of measles in 1411 children under 7 years of age in 9 counties and cities of Nanyang was conducted. After statistical analysis, the measles vaccine immunization was the main way to raise the antibody level in the younger age group. Antibody-bound individuals with age-related limitation of 1-year-old to 6-year-old have decreased their GWT year by year, but there is a significant difference between the GWT and the positive rate. Therefore, the main significance of strengthening the measles vaccine for children of 7 years of age lies in increasing the chances of immunization of trapping. The differences in the GMT of measles antibody-positive children and counties in all counties reflect the imbalance in job-setting. Therefore, as accurate as possible to control the number of children, increase the chances of timely immunization, and ensure the quality of vaccination is the key to further raise the antibody level of children under 7 years of age and reduce the outbreak point.
