The present invention relates i.a. to EHV vectors comprising at least one (at least two) exogenous antigen encoding sequence relating to a pathogen infecting food producing animals, said exogenous antigen encoding sequence is inserted into an insertion site (preferably ORF70) and said exogenous antigen encoding sequence is operably linked to a promoter sequence (preferably promoter sequence comprising 4pgG600 (SEQ ID NO:1) or 4pMCP600 (SEQ ID NO:2) or the complementary nucleotide sequences thereof or a functional fragment or a functional derivative thereof or the complementary nucleotide sequences thereof). Furthermore, the present invention relates to methods for immunizing a food producing animal comprising administering to such food producing animal an immunogenic composition of the present invention. Moreover, the present invention relates to methods for the treatment or prophylaxis of clinical signs caused by swine influenza virus in a food producing animal of need.
