World first: Koala gets life-changing two-shot chlamydia vaccine

An 18-month-old koala named Bamse has made history by receiving the first two-shot chlamydia vaccine, marking a significant milestone in treating koalas suffering from the sexually transmitted infection. This new double-dose format is a game-changer, enabling large-scale treatment that could help save Australia's endangered koala population. The vaccine, developed in part by Queensland University of Technology, underscores the urgent need to protect biodiversity and highlights the innovative approaches scientists are taking to combat infectious diseases in wildlife.
