Professor Timms said.<\/p>\n<p>&#8220;Some individual wild colonies, where infection rates can be as high as 70%, are edging closer to extinction every day.<\/p>\n<p>&#8220;We were determined to do the hard yards to move from research to this vital next stage\u2014a high-quality, veterinary-approved product that can now be used in wildlife hospitals, veterinary clinics and in the field to protect the nation&#8217;s most at-risk koalas.&#8221;<\/p>\n<p>Until now, antibiotics were the only treatment available for infected koalas, but they can disrupt a koala&#8217;s ability to digest eucalyptus leaves\u2014its sole source of food\u2014leading to starvation and, in some cases, death. They also often fail to prevent future infection, leaving populations vulnerable.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Fighting_chance_Pathway_to_a_vaccine\"><\/span>Fighting chance: Pathway to a vaccine<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A decade of clinical data, gathered through multiple vaccination trials, confirmed the vaccine&#8217;s safety and effectiveness.
