Australian zoo saving baby elephants from killer virus

Key points

• Three young elephants at Werribee Open Range Zoo are the first from Australia to join a vaccine trial against elephant endotheliotropic herpesvirus, known as EEHV. The virus has no cure and can kill young Asian elephants within 24 hours by causing internal bleeding.
• Zookeeper Lucy Truelson said the zoo's elephant Man Jai died of the virus three years ago at the age of nine. Researcher Tabitha Hoornweg, of Utrecht University in the Netherlands, leads the trial.
• Eleven elephant calves have been vaccinated across Europe so far.
