Medical researchers are working on a vaccine¹ for lymphoma, a blood cancer that afflicts² both humans -- and dogs.   In fact, the veterinary school at the University of Pennsylvania is working closely with the university's medical school to develop a vaccine for lymphoma that could prevent the disease in dogs, and then someday perhaps, prevent people from getting this form of cancer.  VOA's Carol Pearson has the story.
