I agree, and it's possible he may overestimate the variety of mechanisms the virus deploys, but the potential for a vaccine is limited by all previous SARS dead or attenuated virus vaccines causing higher morbidity and mortality, rather than immunity.

I had hoped that SARS vaccine trials, and possibly wider vaccination, explained the far higher infection impact in China, but the recent exponential growth in Italy, Iran, and soon everywhere, belies that hope. Other forms of vaccine remain possible, and DRACO yet may offer a cure.

Nothing is presently being manufactured that might prevent or cure this disease, and that's the situation we should anticipate continuing for the foreseeable future.
