摘　　要： 本研究采用鸡胚连续传代的方法,使自然鸽痘强毒致弱,从而获得一株免疫原性好、安全且使用简便的鸽痘弱毒疫苗株。结果表明弱毒株所制疫苗接种鸽体后10～14天,便产生最少达9个月的坚强免疫力,现场试验的保护指数在88以上,使用于出壳当天的雏鸽也未见有任何不良的接种反应。置零下28～30℃冰箱中疫苗及其种毒分别经12、24个月效果均未受影响。 Attenuation of pigeon pox virus by serial passage in chick embryos was conducted. The results indicated that the virus lost its pathogenicity to pigeons after 15 passage. The pigeons vaccinated, even at one day of age, had established an immunity for more than 9 months since 10~14 days after inoculation, without any undesirable side effects. The vaccine protective index was 88~92. The vaccine preserved as long as 12 months at minus 20~30℃.
