澳大利亚对野生小企鹅进行大规模禽流感疫苗接种

澳大利亚维多利亚州正在对野生小企鹅进行禽流感疫苗接种，这被认为是全球规模最大的野生鸟类疫苗接种计划1。超过1000只小企鹅已接种第一剂H5N1疫苗，约5000只企鹅将在菲利普岛和圣基尔达岛完成两剂疫苗接种，每剂之间间隔三周1。

近期菲利普岛、袋鼠岛和塔斯马尼亚州金岛均发现禽流感确诊或疑似病例，促使该计划加速推进1。菲利普岛的小企鹅种群约有40000只，该岛每年吸引约70万游客，为维多利亚州贡献约5亿澳元经济价值1。维州环境部长雅克琳·塞梅斯表示，小企鹅是标志性物种，对地区和维州具有重要经济价值1。

根据研究报告，企鹅需要10周时间才能达到免疫峰值1。在最坏情况下，该地区可能有16000只企鹅死亡1。该疫苗接种计划旨在防止这一灾难性后果。

Australia's Victoria State has undertaken what is believed to be the world's largest wild bird vaccination program, inoculating more than 1,000 little penguins against H5N1 bird flu 1. Approximately 5,000 penguins across Phillip Island and St Kilda Island are scheduled to receive two doses of the vaccine, administered three weeks apart 1. The accelerated campaign follows recent confirmed cases of avian influenza detected on Phillip Island and in South Australia 1.

The vaccination effort addresses a critical threat to a species of significant ecological and economic importance. Phillip Island's penguin population numbers around 40,000 and attracts approximately 700,000 visitors annually, contributing roughly AU$500 million to Victoria's economy 1. According to research, little penguins require approximately 10 weeks to reach peak immunity following vaccination, with projections suggesting that without intervention, as many as 16,000 penguins could die in a worst-case scenario 1. Victoria's Environment Minister Jaclyn Semes emphasized that little penguins are an iconic species with substantial regional and state economic value 1.
