Re: #2 -For vaccines, that seems unlikely given that companies with the highest probability of success are already pouring money into this. A clear benefit of the proposal is to reduce risk that if they fail, which is very plausible, or are less effective than at least some alternatives, which is even more likely, the competition will be months and months behind. And for other equipment, it seems even less likely.
