| Abstract: | Marek's Disease(MD)vaccine(CVI988/Rispens)produced domestically by the use of the imported Seed Virus of serotype I vaccine strain CVI988/Rispens from the Netherlands was tested for its efficacy in two trials.One day old SPF chickens were all vaccinated with 3 batches(01,02 and 03)of the home grown vaccines and 1 batch of the imported commercial product.Challenge was all done at 7 days postvaccination using the blood virus of viulent MD virus(strain J 1).The protection indices(PI)obtainded at 60 days of age were 90.0,90.0,93.3 in the lst trial and 100.0,100.0,94.5 in the 2nd respectively,compared to 93.3 and 100.0 of the imported vaccine without a significant difference(P>0.05).The results showed that all the vaccines(CVI988/Rispens)of the two different sources provided high rate of protection against the vMDV,and that the protective efficacy of CVI988/Rispens vaccine domestically developed reached the advanced leval of the same kind imported.
