Both were injected by scientists with dead tumours. Clinky produced no antibodies, but Cedric did and appears to have built-in defences against the mystery illness.

Scientists hope marsupials that share his genetic pattern could also be immune to the cancer or capable of responding to a vaccine.Scientists hope marsupials that share his genetic pattern could also be immune to the cancer or capable of responding to a vaccine.
If real progress is not made soon, experts worry that the Tasmanian Devil could be extinct within 20 years.If real progress is not made soon, experts worry that the Tasmanian Devil could be extinct within 20 years.
