The first vaccine to protect endangered koalas from chlamydia has officially been approved in Australia. “The vaccine has been trialled on hundreds of wild koalas, others in captivity and wildlife hospitals, and over multiple generations.”[ Related: Wild koalas are getting vaccinated against chlamydia. ] The vaccine itself is based on the Chlamydia pecorum’s major outer membrane protein (MOMP) and three crucial levels of protection. Australia Zoo Wildlife Hospital, owned by the family of the late “Crocodile Hunter” Steve Irwin, also contributed to the vaccine trials. Funding and major donations to ensure that the vaccine can be rolled out across Australia are also needed.
