US Patent 7795020 Tumor cell vaccines

An effective cancer cell vaccine for canines has been developed. The vaccine is prepared from autologous lymphoma cells transfected with emm55. Once an animal is vaccinated, the expressed Emm55 antigen stimulates an immunogenic response to the tumor cells resulting in significantly increased survival, strong autologous and cross reactive humoral and cell mediated responses in several breeds of dogs diagnosed with later stage lymphomas.
