作者使用单向辐射状溶血试验和 RIA 两种方法检测123名志愿者接种风疹疫苗后6～ 16年的抗体水平。123名受种者分为两组:第一组85人,6～8年前曾分别接种 RA27/3、Cendehill、HPV77-DES 或日本 To-336风疹活疫苗,另9名在此期间感染自然风疹的志愿者一并观察;第2组38人,11～16年前接种 RA27/3或 Cendehill 疫苗。用 RIA 检测风疹特异性 IgG,有110人(89.4%)抗体浓度高于最低免疫滴度(>15,000 IU/L),11
The authors tested the antibody levels of 6 to 16 years after immunization with rubella in 123 volunteers using one-way radial hemolysis and RIA. 123 raccoon dogs were divided into two groups: the first group of 85 people were vaccinated with RA27 / 3, Cendehill, HPV77-DES or Japanese To-336 rubella vaccine 6-8 years ago, and the other 9 were naturally infected during this period Rubella volunteers were observed; Group 2 38 were vaccinated with RA 27/3 or Cendehill 11-16 years earlier. Rubella-specific IgG was detected with RIA, with 110 (89.4%) antibody concentrations above the minimum immunologic titer (> 15,000 IU / L), 11
