# A vaccine to treat chlamydia in Australia’s koala population has been approved in a world-first project. Researchers developed the vaccine to protect the famed marsupial. Chlamydia is responsible for half of koala deaths in the country’s wild populations, which are predominantly found in the eucalyptus forests along the east coast. Often used as an emblem of local culture, the animals can only be found in Australia. The creatures are also vulnerable to habitat loss, animal attacks and being hit by cars, and were named critically endangered in 2022.
