Embodiments of the present disclosure concern oncolytic viruses, such as vaccinia virus, for example, for the treatment of cancer, wherein the viruses encode an engager molecule having an activation domain that recognizes a cell molecule, such as CD3, for example, on T cells and an antigen recognition domain that recognizes a tumor antigen, such as EphA2, HER2, GD2, or Glypican-3, for example. In some embodiments, the engager molecules further comprise a cytokine or co-stimulatory domain, for example. Methods of treating cancer using one or more of the compositions are encompassed in the disclosure. 1. An oncolytic virus that encodes a bipartite molecule comprising a single chain variable fragment (scFv) specific for a cell surface molecule and a scFv specific for a tumor antigen.2. The virus of claim 1 , wherein the cell surface molecule is on effector cells.3. The virus of claim 2 , wherein the effector cells are T lymphocytes.4. The virus of claim 1 , wherein the tumor antigen is selected from the group consisting of EphA2 claim 1 , HER2 claim 1 , or GD2.5. The virus of claim 1 , wherein the cell surface molecule is selected from the group consisting of CD3 claim 1 , CD4 claim 1 , CD5 claim 1 , CD8 claim 1 , CD16 claim 1 , CD28 claim 1 , CD40 claim 1 , CD134 claim 1 , CD137 claim 1 , and NKG2D.6. The virus of claim 1 , wherein the cell surface molecule is CD3.7. The virus of claim 1 , wherein the oncolytic virus is vaccinia virus claim 1 , adenovirus claim 1 , Herpes simplex virus 1 (HSV1) claim 1 , myxoma virus claim 1 , reovirus claim 1 , poliovirus claim 1 , vesicular stomatitis virus (VSV) claim 1 , measles virus (MV) claim 1 , or Newcastle disease virus (NDV).8. A method of treating an individual for cancer claim 1 , comprising the step of delivering to the individual a therapeutically effective amount of the virus of .9. The method of claim 8 , wherein the amount of the virus comprises 10-10pfu of the virus.10. The method of claim 8 , further comprising the ...
