doesn't the regulatory framework allow such changes though? afaik we aren't doing any phase 3 trials for the annual flu shot, or are we? (genuine question) But if we aren't, couldn't we just expand this to also take into account the Covid-shot?

The flu shot gets a special exception to the process. They study safety every year, but not effectiveness. This takes months off the development time.
