         61 . The method of  claim 60 , wherein the adjuvant is GM-CSF. 
     
     
         62 . The method of  claim 61 , wherein the composition is provided in a therapeutically effective amount sufficient to treat a cancer associated with CMV in the subject. 
     
     
         63 . The method of  claim 62 , wherein the cancer associated with CMV is a glioblastoma. 
     
     
         64 . The method of  claim 62 , wherein the cancer associated with CMV is a breast cancer. 
     
     
         65 . The method of  claim 51 , wherein the composition comprises a glycoprotein UL55 (gpUL55; a/k/a gB). 
     
     
         66 . The method of  claim 65 , wherein the composition is provided in a therapeutically effective amount sufficient to treat a cancer associated with CMV in the subject. 
     
     
         67 . The method of  claim 66 , wherein the cancer associated with CMV is a glioblastoma. 
     
     
         68 . The method of  claim 66 , wherein the cancer associated with CMV is a breast cancer. 
     
     
         69 . The method of  claim 65 , wherein the composition further comprises at least one adjuvant. 
     
     
         70 . The method of  claim 69 , wherein the adjuvant is selected from at least one of: GM-CSF, G-CSF, IL-2, IL-4, IL-7, IL-12, IL-15, IL-21, TNF-α, and M-CSF.
