Dumb question here but that's because I'm unlearne

Dumb question here but that's because I'm unlearned in the ways of the FDA. So it seems like if, by some miracle, we suddenly get emergency approval for severe/critical...not just emergency authorization, but approval. Does that make HIV just a label expansion and possibly move things along quicker for HIV? Wondering if that is a possible methodology to the madness that is our initial BLA perhaps a feet dragging thing for a week or two. If S/C trial is told to fill then resubmit BLA. Just curious...
