Abstract:

笔者对143名4~7月龄婴儿麻疹胎传抗体及其对麻疹疫苗的免疫应答情况进行了研究,结果表明:4~7月龄婴儿麻疹胎传抗体的阴性率为75.00%~94.87%,且6~7月龄婴儿较4~5月龄婴儿的阴性率更低(χ²=5.11,P<0.05);而4~7月龄婴儿初免麻疹疫苗后,其免疫成功率为84.38%~100.00%,6~7月龄婴儿的免疫成功率显著高于4~5月龄的婴儿(χ²=5.37,P<0.05),GMT在各月龄组婴儿中的差异亦存在显著性意义(F=5.40,df=3,P<0.01)。另外,初免麻疹疫苗前麻疹抗体的滴度对免疫应答结果有明显的影响。综合以上结果,笔者认为要减少1岁内婴儿(尤其是9月龄以下婴儿)麻疹的发病,应将麻疹疫苗的初免时间提月龄。

English Abstract:

A total number of 143 infants at the age of 4 to 7 months from Yantai city-Shandong was selected for the study of antibody level against measles by maternal-fetal transfer and immuno-res-ponse to measles vaccine in October of 1993. The results showed that the negative rates of maternal-fetal antibody among infants of 4, 5, 6 and 7 month olds were 75.00%, 81.25%, 94.87%and 90.91%, respectively. The positive rates and geometric mean titers (GMTs) for immuno-response to measles vaccine were 92.86%, 84.38%, 97.44%, 100.00% and 55.17, 42.41, 69.95, 71.46, respectively. There was significant lower immune response to measles vaccine in infants who had high titer (>1:2) than those who had low titer (≤ 1:2) of maternal-fetal antibody (χ²=88.38, P<0.001). In order to decrease the number of measles cases under 1 year old (especially under 9 month-old), the author suggested that the primary immunization for measles vaccine should be started at 6 month olds.
