If the purpose of the vaccines is to cause your body to produce the spike protein to generate an immune response then why didn’t they just create and inject spike proteins as the vaccine? That seems like a much simpler solution.

I think this is called a subunit protein vaccine. Novavax is the only one that I know of. I haven’t read much about it as it is not available in the U. S.
With any of the routes that we have available in the U. S. today, i.e. wait to get infected, vaccinate with an mRNA vaccine (Modern or Pfizer), or vaccinate with a vector virus vaccines (J&J), your ribosomes are going to be using mRNA to be crank out spike proteins (and a lot of other stuff besides if you get infected.)
