There has been a lot of work on how to best design a vaccine against coronaviruses in general.

By using more than one feature of the virus (epitope) to train the immune system, more viral variations can be resisted. If you pick them carefully, relatively few epitopes are needed to stimulate wide resistance across the whole family of Coronaviruses.

Some experimental vaccines that I have heard of use as few as three, others up to twelve. The Walter Reed Army Institute of Research (WRAIR) has a broad spectrum coronavirus vaccine in development, as do several other research organizations in the USA.

Whole coronavirus vaccines can produce severe and fatal reactions (such as ADE), so excluding the problematic epitopes for safety is vitally important, in addition to choosing the right ones for effectiveness.

So far, it looks very promising that vaccines will be able to be made for coronaviruses in general, but it is not a near term prospect (multi-year). If it was needed on an emergency basis however, we are pretty far down the road of figuring out how to best configure one, and mRNA technology would allow for very rapid creation and production.

The problem with mRNA "vaccines" is still the same - you aren't training your body to fight off invaders, you're training your body to build stuff it then has to fight. mRNA modifications do NOT produce antibodies, they force your body to produce fake virus particles, which your body then has to identify as 'bad', even though your own body produced them, and then you produce the antibodies. Against your own body production.

Sure, it's good to train your body to defend against invaders in multiple ways, but having you produce those bad guys yourself is not a good idea. That's just asking for auto-immune issues.
