"Because scientists were working for decades or more on Sars vaccines and also on Mers vaccine, they found out some very key pieces of information about coronaviruses... If we do that kind of homework on every one of the 25 or so viral families that we already know have the potential to cause disease in humans ... then we can actually gain a lot of knowledge ahead of time about something that doesn't exist yet."
Given researchers aren't working with a known pathogen - it's just assumed a really bad one will emerge at some point - work to prevent an ensuing global pandemic is hypothetical at best.
