Comparison of vaccination results of different live vaccines against classical swine fever from three biopharmaceuticals
Abstract：In order to investigate the vaccination results of different live vaccines against classical swine fever （CSF） produced by different veterinary biopharmaceuticals, 3 vaccines manufactured using bull testicular （BT） culture and one vaccine produced using swine testicular （ST） culture were used for the experiments in selected swine farms. Our results showed that the vaccination results revealed by the titers and durations of specific antibody, of ST cell-originated live CSF vaccine is, as the whole, more effective than those of three BT cell-originated live CSF vaccines, in which two of those BT cell-originated CSF vaccines are superior to another one. The effective antibody titers preventing CSF virus infection were reached in pigs after only one vaccination with ST cell-originated live vaccine, however, this protective antibody levels can only be reached by twice vaccinations when the BT cell-originated vaccines were used. Furthermore, we also found that vaccinating the attenuated live highly pathogenic PRRS vaccine in pigs could potentially interfere the production of antibodies against CSF virus.
