Elephant virus vaccine trial under way at Chester Zoo

Chester Zoo is embarking on a world-first trial of a vaccine that could save the lives of young elephants.

It’s designed to protect the animals from a common and very dangerous virus called elephant endotheliotropic herpes virus.

The disease is responsible for more than half of the deaths of Asian elephants in zoos and is a significant threat to elephants in the wild.
