Credentialism aside, there were no sources provided.

I do find the point about no SARS vaccine compelling, however. Is that true?

I know the flu vaccine gets updated every year or so with new viruses that are prevalent, so if there is no SARS vaccine then I wonder if that is true and if it is true it couldn't be developed.

Again, multiple things thrown out there without sources which are not common knowledge, followed by "you can look this up yourself".

Wikipedia says so, and just gives essentially the same advice as being given for SARS-CoV-2 (or any human-transmissible virus, I imagine).
