Abstract: The present disclosure provides a pseudorabies virus (PRV) expressing a porcine circovirus 2 (PCV2) capsid protein in its envelope, and use thereof. In the present disclosure, an attenuated PRV vaccine strain is used as a vector to express an exogenous immunogen. The exogenous immunogen only replaces an extracellular domain of a non-essential envelope protein of the PRV, while retaining a transmembrane domain and an intracellular domain of an original envelope protein, thereby allowing the expression of one or more exogenous immunogens on the viral envelope without changing genes of other PRV autoimmunogens. During the recombinant PRV particle being recognized by the body's immune system, the host's immune system recognizes all immunogens (exogenous immunogens and PRV autoimmunogens) on the recombinant PRV particle and then initiates an immune response, thus exerting a protective effect of a bivalent vaccine or a polyvalent vaccine based on the recombinant PRV particle.
