1991年1～7月,江陵县部分乡镇农场发生较大麻疹暴发流行。4月中下旬,对已暴发或受到严重威胁的71个村8个月～15岁儿童进行了麻疹疫苗应急接种,每人0.2 ml。应种29282人,实种18292人,接种率62.47％。对其中96名儿童进行血清学效果观察,于接种前和接种后一个月采滤纸全血,用ELISA法测定麻疹IgG水平。结果在96人中,57人抗体水平呈≥4倍增长,应急接种成功率为59.38％。麻疹IgG阳性率(IgG≥1:200为阳性)和GMT,接种前、后分别为69.79％、98.96％和1:61.79、1:679.34。达保护滴度(≥1:800)人数由接种前的15人(15.63％)增加到
From January to July 1991, some measles outbreaks occurred in some towns and villages in Jiangling County. In late April, emergency vaccination against measles at a rate of 0.2 ml was conducted in 71 villages of 8 months to 15 years of age which were already outbreaks or were seriously threatened. Should be planted 29282 people, real species 18292 people, vaccination rate of 62.47%. One hundred and ninety-six children were serologically observed, whole blood was collected before inoculation and one month after inoculation, and measles IgG level was determined by ELISA. Results Among the 96 people, the antibody level of 57 people showed a ≥4 fold increase, and the success rate of emergency inoculation was 59.38%. The positive rate of measles IgG (IgG≥1: 200 was positive) and GMT were 69.79%, 98.96% and 1: 61.79, 1: 679.34 respectively before and after inoculation. The number of protection titers (≥1: 800) increased from 15 (15.63%) before vaccination
