It's such a shame, too. You can likely re-freeze the spikevax vials with partial shots to be used at a later date, but that's too uncontrolled to add to the EUA/BLA label. Comirnaty is (was) in phosphate buffer and saline, which you really cannot re-freeze. They did just request a formulation change to the same composition as spikevax (or at least very similar), which should also get rid of the saline dilution step making it overall much easier to administer.
