摘要: 为有效地预防肾综合征出血热(HFRS)的发生与流行,对沙鼠肾细胞型灭活疫苗的安全性及血清学、流行病学效果进行观察。结果:疫苗接种总反应率0.89%(557/62311),中反应率0.03%(19/62311);疫苗基础免疫全程接种两周后的血清中和抗体阳转率70.37%(38/54),荧光抗体阳转率83.33%(25/30);垦区HFRS冬季主要宿主动物为黑线姬鼠,占62.61%(360/575),野外黑线姬鼠密度11.13%(204/1833),带病毒率6.0496(9/149),带病毒鼠指数0.0820;HFRS病人血清IgG抗体检测为Ⅰ型,流行峰型为冬峰型,秋冬季节(8~1月份)发病人数占93.91%;健康人群隐性感染率3.47%(56/1616)。1995年10~12月份,疫苗全程接种组人群HFRS发病率0(0/17127),全程非接种组人群发病率101.36/10万(144/142061),保护率100%。由此显示:黑龙江垦区HFRS疫区类型为姬鼠型;该疫苗具有较高的安全性和较好的近期防病效果。

Abstract: Evaluation on the safety, immunological and preventive effects of inactivated HFRS vaccine produced from primary tissue culture of Mongolian gerbils kidney by Tianyuan Company, Hangzhou, was carried out in population in reclamation areas, Heilongjiang province from 1994 to 1995. The results showed that,the rate of total side effects of the vaccine was 0. 98%(557/62311),the rate of moderate and severe side effects was 0.03 % ( 19/62311).Two weeks after the third dose of immunization, the seroconversion rates were 70. 37%(38/54)by neutralization tests,83. 88%(25/30)by indirect immunofluorescent antibody tests.According to the epidemiological properties and serotyping results by IgG-ELISA of HFRS patient sera, the endemic area for evaluation was HTN type focus. For the evaluation, 17127 volunteers were vaccinated, 142061 nonvaccinated people lived in the same areas with the vaccinees were used for controL One year's observation showed that the protection rate was 100 %. All these showed that the vaccine was safe and effective.
