A regulator in Australia has approved a world-first vaccine to protect koalas from chlamydia. The disease causes infertility and high death rates in this endangered animal. The vaccine, created after more than ten years of research at the University of the Sunshine Coast in Queensland, was announced recently. Studies showed that the vaccine reduced the chance of koalas developing symptoms and lowered death rates in the wild by 65 percent. Approval allowed its use in wildlife hospitals, veterinary clinics, and conservation areas. Reports said that chlamydia caused almost half of koala deaths, with infection rates in some regions reaching 70 percent.

The new vaccine was seen as a remarkable step for conservation. Still, experts warned that habitat loss from fires, urban growth, and climate change continues to intensify the threat. The project was called a constructive and advantage for science, but also challenging because it requires more funding and support.
