Live recombinant vaccine comprising inefficiently or non-replicating virus

摘要

The subject invention pertains to a novel recombinant vaccinia virus vaccine for use in immunizing animals and humans against disease. The vaccine comprises a live vaccinia or replication deficient mutant vaccinia virus capable of expressing a single or multiple heterologous genes or gene fragments. In a preferred embodiment, the recombinant virus is contained in an orally-administered package that will only dissolve in the host animal's gut. The subject invention also pertains to a method of inducing a broad protective immune response through the oral, intranasal, or other mucosal means of administration of the recombinant vaccinia virus vaccine.
