Bivalent vaccine composition for preventing and/or treating porcine circovirus infections and preparation method and use thereof

摘要

A vaccine composition for preventing and/or treating porcine circovirus infection is described, which comprises an immunogenic amount of porcine circovirus type 3 antigen, an immunogenic amount of porcine circovirus type 2 antigen and a pharmaceutically acceptable carrier. The vaccine composition can not only prevent and/or treat related diseases caused by infection or mixed infection of different gene subtypes of porcine circovirus, but also have immunoprotective effects against strains of different geographical origins.
