Comparative estimation of antigenic and immunogenic activity of commercial live vaccines against classic hog cholera

The authors determined the antigenic and immunogenic activity of three commercial live vaccines against classic hog cholera (Plivac, LK-VNIIVViM and KS NPO «Narvak»). It was shown, that all vaccines are harmless and arectogenic for the pigs and have the pronounced antigenic and immunogenic properties. Variations in vaccine antigenic activity depend on different content of vaccine virus in original preparation.
