I read in the news that they are working on a vaccine for avian bird flu in chickens. Do you think they will succeed in an avian bird flu vaccine for chickens?

I don't really know, do you know how much effort there is to this end?
I could be wrong but it seems every year there is a new variant so I don't know how successful it would be.
