Australia approves world-first koala chlamydia vaccine

Australia has approved a world-first vaccine to combat the chlamydia epidemic devastating koala populations. The single-dose vaccine, developed over a decade by UniSC scientists, significantly reduces chlamydia symptoms and mortality in koalas, which can cause blindness and infertility. Chlamydia is a major threat to koalas, contributing to thousands of deaths and an estimated remaining wild population of only 50,000.
