The koala population in Australia is facing a severe decline due to a chlamydia epidemic that threatens their survival. With estimates suggesting their numbers have dropped by up to 80% in some regions, wildlife hospitals like Currumbin Wildlife Sanctuary are racing against time to vaccinate affected koalas. Two separate vaccines are in development, with ongoing trials aiming to provide hope for recovery. However, funding and logistical challenges complicate the path to widespread vaccination, leaving the fate of these national icons in jeopardy.
