So it sounds to me like antigen express tinkered with or thought about SARS and there ability to create a vaccine, it's unclear if they did or simply thought they could.
Now we are contemplating a potential deal with China, presumably because they would pay for the needed cost of study and formulation of the vaccine, it appears to me that regardless of the China negotiations, as soon as the S1 is finished and funds are available, we should create the vaccine ourselves and show the world or tech.
