[Protective medium for the lyophilization of a live vaccine against swine erysipelas--VR2].
Hydrolysate was obtained through enzyme hydrolysis from waste residual fibrin in the production of hyperimmune swine blood. Fibrin hydrolysate and gelatose in 2.5 : 1.5 ratio were tested as protective medium for the freeze-drying of VR2 vaccine against swine erysipelas. It was found that the freeze-drying of the vaccine with the addition of the hydrolysate-gelatose medium at the rate of 4-5 per cent of the vaccine volume met the requirements of the standard for sterility, innocuity, vaccinal titer, and residual moisture.
