Australia approves world-first koala vaccine against chlamydia

Australia has approved a world-first vaccine to protect koalas from chlamydia, a disease causing infertility and death in the iconic marsupial. Developed over a decade, the single-dose vaccine has shown to reduce chlamydia symptoms and mortality in wild koalas by at least 65%, offering hope for endangered populations. While welcomed, some conservationists emphasize that habitat preservation remains crucial for koala survival, alongside disease management efforts.
