<p>A vaccine containing Mycobacterium bovis BCG which secretes a fused protein obtained by inserting a foreign antigen peptide to the surface of a molecule of a secreted protein having a signal peptide as a carrier. The BCG secretes a fused protein obtained by inserting a foreign antigen peptide to the surface of a molecule of an α-antigen originating in an acid-fast bacterium. As the fused protein has extremely enhanced antigenicity and immunogenicity, it is recognized, when inoculated into animals, by B cells which efficiently recognize the α-antigen, and can effectively induce the production of an antibody against the α-antigen. When the BCG itself is inoculated into an animal, it continues to secrete the fused protein while continuing to grow in the animal body, thus providing a very useful vaccine.</p> |
