Resolves YES if a "universal flu vaccine" has entered phase III trials by the beginning of 2026. See, eg, recent news.

I'm using "universal flu vaccine" colloquially for the purposes of this question--it wouldn't need to target every possible flu strain but might, for example, target certain elements of a virus common to the majority of flu viruses that infect humans.
