In 1993, an official with the Center for Disease Control and Prevention (CDCP) called a few employees into her
office and asked the question: what was the CDCP doing about the risk that animal-to-people transplants might
introduce new germs into the human population? “My first reaction was—nothing,” recalled Louisa Chapman, an
expert on animal viruses that infect humans. “Transplants from animals were so rare, and recipients lived so briefly
that it didn’t seem a threat.”
But as she looked into the situation, she changed her mind. Interest in xenotransplants was heating up. Animals
could not only ease the shortage of kidneys, hearts, and livers for transplantation, but also supply brain tissues for
treating diseases like Parkinson’s. These days, drug and biotech companies have poured more than $100 million into
xenotransplant research. Scientists have reported progress in overcoming rejection of animal organs. But the concern
Chapman heard in that 1993 meeting has not gone away: would xenotransplants give new germs a sneaky entrée into
the human population?
