New Vaccine for Osteosarcoma in dogs

A new vaccine for osteosarcoma in dogs is being tested and has shown promising results. Dogs diagnosed with osteosarcoma currently face a grim prognosis. With aggressive surgical resection (amputation) and chemotherapy, survival times are generally around a year.

In contrast, dogs in the trial group with the new vaccine have lived up to 4 to 4 1/2 years. The vaccine is administered after surgical resection and chemotherapy. It is given as three doses, two weeks apart, then every 6 months.

Dr. Mason said: “These dogs live normal lives. They have an excellent quality of life. If you look at these dogs, other than the fact that they are missing a limb, you wouldn’t know anything’s wrong with them.
