I think too, Jim, just to kind of go back to the point here on CEPI, as I understand it, their calls really are going to pan coronavirus vaccines, and in particular hitting on themes that we're hitting on here too for us to have relevance, right? So, once again, it's durability, access and the variants, right? And I think here and along the way, we'll be looking at seeing how much of a contribution that we can make towards providing a differentiated product and watching how the pandemic unfolds with the existing vaccines and their ability to provide a durable immune response. If this continues, and you're looking at something on the order of six months or seven or eight months or whatever that may be, and that's not to speak generally. I don't think there's enough data that's in there. But I'm just prospectively – as we think about our role here, if that turns out to be the case, well, then the capacity that we have and the potential for nucleocapsid based protein to provide more durability and more coverage for the variants will be important. But then also too, if one looks at COVAX and that organization and how it's relating to the World Health Organization, this pandemic raging in India, the impact of the P.1 variant down in Brazil, and so much more indicates that we may very well need more solutions. And if we can't get non-dilutive government funding, well, then it is a question. Can we and should we, on our own, fund a Phase I study, and I think we're going to look at not only the unmet medical needs that are out there, but also the commercial opportunity. If we believe we have a viable product candidate, then indeed we've got the funding in place, we have an understanding of what it would take in terms of the cost for that kind of the clinical trial. But in some respects, we're almost happy that we didn't get selected before because it looks like, in our view, that a spike-only based vaccine, if we're going into a Phase III clinical trial with that right now on our own versus competition, the likes of Pfizer and Moderna, AstraZeneca/J&J, I think that would be pretty tough to be – having to spend that money on a big Phase III with patients difficult to recruit at this point. So, in some ways, maybe we were lucky. But it's a long way of saying, I think, in the end, we'll make the best decision on behalf of prospective patients and our investors. If we think we can bring a differentiated product to market that can be commercially successful, then indeed we intend to move that forward and try to make an important contribution here towards at least mitigating some of the ongoing effects of this pandemic.
