摘要: 我省是肾综合征出血热(HFRS)高发省,近年来年发病7000多例,90%以上的县、市、区都有疫情报告。为此,我们选择姬鼠型疫区,使用兰州生物制品研究所研制的鼠脑纯化HFRSⅠ型灭活疫苗进行了免疫效果观察,共观察8333人(接种者4081人),证实免疫反应率较低(3.19%),未出现异常反应;全程免疫2周后荧光抗体阳转率达83.67%,但中和抗体阳转率仅为31.4%,且两者的GMT都很低,分别为31.45和6.86;隐性感染者接种后未出现异常反应;经过一个流行高峰的观察,该苗近期流行病学效果较好,疫苗保护率达100%。但远期流行病学效果尚有待进一步观察。

Abstract: It is higher of HFRS prevalance in Hunan province. The incidence of HFRS reached more than 7000 cases one year. Epidemics of HFRS have reported in more than 90 percent of counties in this province. Inactivated HFRS vaccines have been developing in China. The immune of HFRS vaccine were conducted in epidemic area. 4081 people were vaccinated, The immune response of the vaccine and the side effects of the vaccine was rare to seen The seroconversion rate of IFA was 83.67%, but the neutralizing antibody was only 31.4%, and the titer of them were all lower. The person who had been infected had no symptom and sign. Observed for an epidemic season of HFRS, it had good recent efficacy and the rate of protection was 100%. But the prevalent efficacy of the HFRS vaccine has to continue for study.
