I think it's an open question. Never has a vaccine had so much scientific muscle behind it, so that means something. SARS vaccines were developed, but none were tested because the outbreak was contained.

But there are lots of diseases we have tried to develop vaccines for and failed. AIDS has killed millions and we still don't have a vaccine despite years and lots of research dollars and focus. We can make effective vaccines for flu (If you get a flu shot and still get the flu it's likely a strain that wasn't well covered in that year's vaccine. COVID won't have that problem, at least not initially), so it's not like we can't make a vaccine for a respiratory virus. I don't think there is a big scientific breakthrough that needs to happen, but it's possible that in spite of the best scientific efforts, we may not be able to make a good vaccine for this particular virus because of issues intrinsic to the virus.
