The present invention provides a recombinant virus containing a nucleotide sequence encoding a tumor-therapeutic full-length antibody with human constant regions, and uses thereof. After a nucleotide sequence of a gene encoding a tumor-therapeutic full-length antibody with human constant regions of the light chain and the heavy chain is inserted into the genome of a recombinant virus, the tumor-therapeutic full-length antibody with human constant regions can be efficiently expressed in tumor cells, thereby inhibit the growth and metastasis of tumors.
