If it did become available, wouldn't it be an issues once the flu mutated again? Like human influenza's?

In the article I posted it explains-

To create the mosaic vaccine, the researchers collected DNA sequencing data from nearly 20,000 strains of avian influenza. This helped them pick the antibodies most likely to ensure that the resulting vaccine protects against several strains of the virus. :)

This is a true concern.

Since it's mainly spread by wild birds should they be eliminated also? That would be unthinkable to me. Although I started discouraging wild birds awhile back due to lice right after the black birds landed, but I don't kill them.
Although I thought about it when a pair of ducks were in the creek.

In Europe and (broadly) the Medieterranean basin, they are doing just that. Even with protected species.

"Several Strains" is not immunity - any more than annual trivalent human flu shots provide immunity to us human-types.

From and HPAI perspective, they are interested in ALL H5 and H7 virii, regardless of the N#. That's an incredible number of variations, and sadly, just targetting the H5 or H7 protein section directly hasn't previously been possible. Perhaps with new methods, such as those used by Pfizer and Moderna to craft the mRNA vaccines, we have some hope - but it will be a mitigation measure, nothing like our successes with, say, Polio.

The thing I found most interesting about that particular article is it said-

“We are one of the few labs in the world trying to use all the sequences that are present in avian influenza in order to develop a vaccine against all of them.”

Today I came across this article https://www.reuters.com/world/us/us-considers-vaccines-protect-poultry-deadly-bird-flu-2022-04-04/

and this https://www.foodsafetynews.com/2022...improved-surveillance-and-some-vaccine-hopes/

From what I've read, the trouble with current poultry AI vaccines is not only mutations and limited immunity but also the testing they use for surveillance during outbreaks can not distinguish between vaccinated and infected birds. That's a real problem when you are trying to cull sick birds.
