What's Happening?
New Zealand has completed a year-long vaccine trial aimed at protecting some of its most endangered bird species from the highly pathogenic avian influenza (HPAI). The trial, conducted by the Department of Conservation (DOC), involved five captive species, including the kākāpō, takahē, kakī, tūturuatu, and kākāriki. Up to 10 birds from each species were vaccinated, focusing on those in captivity where the full two doses of the vaccine could be administered. The trial cost $66,000 and represents a significant step in safeguarding New Zealand's unique wildlife, which has little immunity to the virus due to its isolated evolution. The results of the trial have been shared with Australia, which is also preparing for the potential arrival of HPAI.

Why It's Important?
The vaccine trial is crucial as it addresses the threat of extinction faced by New Zealand's endangered bird species due to avian influenza. With New Zealand having the highest proportion of threatened species globally, the trial's success could help prevent significant biodiversity loss. The initiative also highlights the importance of international collaboration, as New Zealand shares its findings with Australia, which faces similar challenges. The trial's outcome could influence policy decisions in Australia regarding the vaccination of priority threatened species in captivity, potentially enhancing biosecurity measures and conservation efforts.
What's Next?
Australia is considering the vaccination of its threatened species in captivity, building on existing biosecurity measures. The country's Department of Agriculture has advised that vaccination should complement effective biosecurity rather than replace it. The Australian government has announced investments to improve quarantine populations of species like the plains-wanderer and Regent honeyeater. These efforts are part of a broader strategy to protect native fauna from HPAI, with a $35.9 million fund earmarked for conservation initiatives. The collaboration between New Zealand and Australia may lead to further joint efforts in combating avian influenza and preserving biodiversity.
