That's sensible. Do we know how effective the h5n1 vaccine is, given that bird flu is so rare in humans to begin with?

We don't "know know" because the infections are so rare and the virus is so dangerous. This is not a virus where one would do human challenge tests.

We do know what a successful flu vaccine match looks like though, and in animal tests (like the one linked) it shows what we want to see.
