Immunogenicity of BHK-Rabies Vaccine in Cattle

In this study, the immunogenicity of a rabies vaccine that was used in one of the Isfahan cattle farms is reported. This vaccine was produced by replication of the Pasteur virus (PV) strain on BHK-21 monolayer cell culture. The virus suspension was inactivated by ß-propiolactone treatment and the harvested pool showed sterility and safety. Thus, the obtained vaccine was tested on mice and a sat...
