Bovine leukemia virus (BLV) infects cattle worldwide, imposing a severe economic impact on the dairy cattle industry. The purpose of this research is to develop a novel vaccine against BLV for eliminating BLV infection. This approach can be applied to other retroviruses including human immunodeficiency virus type 1 (HIV-1) and human T cell leukemia virus type I (HTLV-1) which cause acquired immunodeficiency syndrome (AIDS) and adult T-cell leukemia (ATL), respectively.
