澳大利亚政府正在探索可用于哺乳动物的禽流感疫苗选项 1。环境部长Murray Watt警示称："我们可能会看到鸟类和哺乳动物的大规模死亡" 1。农业部长Julie Collins透露，北美正进行一项使用为牛开发的疫苗的试验，但"目前没有商业化可用的疫苗" 1。
Australian authorities have intensified efforts to vaccinate little penguins against avian influenza following the detection of a second mammal infected with the H5N1 virus. Five suspected H5N1 cases were recorded in South Australia on Monday, including a long-nosed fur seal 1. The first confirmed case of H5N1 in a mammal was identified in a long-nosed fur seal at Beachport on Sunday 1.
In response to the outbreak, Victoria has launched a vaccination campaign targeting approximately 5,000 little penguins across Phillip Island and St Kilda, with roughly 1,000 penguins already receiving their first dose 1. Environment Minister Murray Watt warned that "we may see mass deaths of birds and mammals" 1. Agriculture Minister Julie Collins revealed that North America is conducting trials using a vaccine developed for cattle, though she noted that "there is currently no commercially available vaccine" for this purpose 1. Australian officials are investigating whether any existing avian influenza vaccines could be adapted for use in mammals 1.
