Recombinant viruses and viral nucleic acids are contemplated that provide to the infected cell various regulatory molecules that stimulate T-cell and NK-cell activity and that suppress inhibition of T-cell and NK-cell activity. Most preferably, the virus and viral nucleic acid will further include a human cancer-associated sequence, and especially a sequence that encodes a plurality of cancer associated antigens, cancer specific antigens, and/or patient and tumor specific neoantigens. Especially preferred regulatory molecules include CD80 (B7.1), CD86 (B7.2), CD54 (ICAM-1/BB2), CD11 (LFA-1), and an inhibitor of CTLA-4.
