ABSTRACT:
The invention includes a viral vector method and composition comprising transcomplementary replication incompetent viral vectors, preferably adenoviral vectors, which are cotransformed to a recipient cell. The two vectors complement each other and thus allow viral replication, in a synergistic combination which enhances both gene delivery and gene expression of genetic sequences contained within the vector.
