I would hope the world is working on producing a vaccine 24 and 7 right now. This is no joking matter to be taken lightly. It should be getting every bit of funding that it needs.
The bird flue virus has not evolved to a human transmissable form, yet. until that happens, any vaccine developoed today would be specificn against the un-mutated bird virus and not the type that is extremely virulent against humans. Once that mutation has occurred, then vaccine development is possible. You can't create a vaccince for a disease that does not yet exist.
