作者对1075名成年医护人员采血,用辐射状溶血法(RH)测定风疹病毒抗体。凡测出溶血带直径(D)>6mm者为具有免疫力。检测结果为,84/1075(7.8%)血清阳性(D<4mm);93/1075(8.7%)具有低水平抗体(D=4～5mm)。对上述177人中64名志愿者肌肉接种风疹病毒减毒活疫苗(RA27/3株),分别在接种时及接种后3周和3个月采血。对其中54名接种者随访其免疫应答结果,免疫后3周,血清阴性或具有低水平抗体的个体仅有轻微
The author of 1075 adult health care workers blood collection, determination of rubella virus antibodies by radial hemolysis (RH). Where the measured hemolytic zone diameter (D)> 6mm were immune. The test results were 84/1075 (7.8%) seropositive (D <4 mm); 93/1075 (8.7%) had low levels of antibody (D = 4-5 mm). Sixty-four of the 177 volunteers were intramuscularly immunized with the live attenuated rubella vaccine (RA27 / 3) at 3 and 3 months after inoculation and after vaccination, respectively. Among 54 vaccinated individuals, 54 immunized patients were followed up for immunization. Only 3 weeks after immunization, there were only a few patients with seronegative or low antibody
