Australia is preparing to roll out vaccines against the deadly H5N1 bird flu, with priority being given to vulnerable native bird species kept in captivity. The rollout is expected to begin in the coming days.

Australia has recorded more than 230 confirmed cases of H5N1, while the country experienced its first mass wildlife mortality event linked to the virus last week.

Agriculture Minister Julie Collins said vaccination would form part of the government’s response to protect species most at risk. The exact species to be vaccinated will be decided by individual states and territories based on vulnerability and conservation importance.

The government has secured an initial $2 million worth of vaccines. However, authorities have not yet confirmed how many birds will receive the vaccine.

Wild birds are not the main focus because the vaccine requires two doses, making large-scale vaccination of free-flying birds difficult. Where practical, some wild birds may still be vaccinated.

Australia’s Chief Veterinary Officer Beth Cookson stressed that vaccination is not a standalone solution, as vaccines are not 100 per cent protective. Strong biosecurity measures will remain essential to protecting wildlife and preventing further spread.
