摘要

A method of inducing expression of immune active cytokines in tumors in situ is provided wherein a vaccinia virus vector capable of inducing expression of a selected cytokine is generated and injected into a tumor so that cells of the tumor express the selected cytokine. A method of enhancing immunity in a host by administration of a vaccinia virus vector is also provided. Methods of treating cancer by administration of these vaccinia virus vectors are also provided.
