Vaccinating Birds?

So I don't know if this counts, because it's primarily about birds, however, since the vaccine would be created with intentions of decreasing the spread of this virus from animals to humans, I thought it was relevant... Wait can someone who knows more about this than I do tell me how realistic it is to even do this? Has it been done before? And isn't there still a really high chance that the flu will just mutate?

Russia could develop a bird flu vaccine targeted at wild birds within
2 years, creating a revolution in the flight against the disease, the
chief vet at Russia's food safety watchdog said Tuesday [25 Sep 2007].

"It will, speaking mildly, be a revolution, because no one has ever
tried to control the spread of the flu virus among wild birds. And
this is the source of all the trouble," Nikolai Vlasov said.

Bird flu has never really disappeared from Russia since 2005, Vlasov
told journalists, adding that, out of 100 birds that are culled,
around 2-80 will actually have been infected depending on the location.

According to watchdog estimates, by the end of the year [2007], the
numbers of birds which will die from bird flu outbreaks in Russia
will be 4 times lower than last year's [2006] figure.
