It's not easy to catch, vaccinate and release wolves, so oral vaccines are incorporated into meat left overnight for the wolves. Researchers will continue to monitor the effectiveness of the vaccines, but it's a positive move forward for the species.
The rabies virus can kill entire wolf packs in a short amount of time. Symptoms of rabies infection include pica, hydrophobia, seizures, aggression and paralysis. Prognosis: death. By the time symptoms are obvious, it's too late. Thank you to the hard work of WILDCRU
and scientists working to save endangered animals.
