Australia approves world-first vaccine to save koalas from chlamydia

Australia has approved a world vaccine to protect chlamydia koalas. This disease causes infertility and death in endangered species. Developed by the University of Sunshine Coast, the single dose vaccine reduces symptoms and mortality of at least 65%. Approval means that it can now be used in land and field hospitals. Some environmentalists argue that resources should focus on preserving habitat. Koalas are faced with threats to loss of habitat, climate change and disease. Experts warn that without action, the Koalas could disappear by 2050. The vaccine is part of a wider effort to save them.
