Australia approves first vaccine to protect koalas from chlamydia

A world-first single-dose vaccine has been approved in Australia to protect endangered koalas from chlamydia, a disease causing significant mortality and infertility, with the vaccine shown to reduce symptoms and death rates by at least 65%. Despite this advancement, conservationists emphasize habitat preservation as crucial, as habitat loss remains the primary threat to koalas' survival. The vaccine's development was supported by government funding, aiming to help combat the disease amid ongoing threats to koala populations.
