In a significant move to combat the chlamydia epidemic threatening koala populations, Australia has approved the world’s first vaccine aimed at protecting these beloved marsupials. This groundbreaking vaccine comes after a decade of research dedicated to developing a solution for the disease that has severely impacted koala numbers, with some populations already facing functional extinction. As the rollout begins, conservationists are hopeful that this new weapon will help save Australia’s iconic koalas and curb the killer epidemic they face.
