    本研究应用高致病性猪繁殖与呼吸综合征活疫苗（JXA1－R株）对28～30日龄的仔猪进行免疫，前8周每周采血，8周后每2周采血进行疫苗毒核酸检测，直至免疫后第16周。结果表明，高致病性猪繁殖与呼吸综合征活疫苗（JXA1－R株）在血清中存在的最长时间约为6周，但有的猪呈现间歇性携带疫苗毒。

    Abstact:Immunize the piglets which were 28 to 30-days-old with the JXA1-R strain high pathoge-nicity PRRS (Porcine reproductive and respiratory syndrome) attenuated vaccine. Sampled the blood every week for the first Eight weeks, then sampled two weeks a time untile sixteenth weeks. The samples collected for virus detection. The results showed that the JXA1-R strain high pathogenici-ty PRRS attenuated vaccine can be surviving for six weeks, but some piglets appeared infected by the virus intermittently.
