Abstract
Abstract What are disclosed are methods for modifying the genome of vaccinia virus to produce vaccinia mutants, particularly by the introduction into the vaccinia genome of exogenous DNA; modified vaccinia prepared by such methods; certain DNA sequences and unmodified and genetically modified microorganisms involved as intermediates in such methods; and methods for infecting cells and host animals with such vaccinia mutants to provoke the amplification of exogenous DNA and proteins encoded by the exogenous DNA, including antigenic proteins, by said cells and host animals.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
25 words
A recombinant vaccinia virus synthetically modified by the presence, in a non-essential region of the vaccinia genome, of DNA not naturally occurring in vaccinia virus.
Claim 2
Dependent Claim
25 words
A recombinant vaccinia virus synthetically modified by the presence, in a non-essential region of the vaccinia genome, of DNA not naturally occurring in vaccinia virus.
Claim 3
Dependent Claim
21 words
A vaccinia virus as in claim 1 wherein said DNA is expressed in a host by the production of a protein.
