Recombinant swinepox virus

摘要

This invention provides a recombinant swinepox virus comprising a foreign DNA sequence which is (a) inserted into the swinepox virus genomic DNA, wherein the foreign DNA sequence is inserted within a region of the genome which corresponds to the 2.0 kb HindIII to BglII subfragment located within the HindIII M fragment of the swinepox virus genome and (b) is expressed in a swinepox virus infected host cell. The invention further provides homology vectors, vaccines and methods of immunization.
