I don't think weakened viruses go through our protein-making machinery (aka code execution), but directly cause immune system reactions. Edit: I stand correcte

  Viral vectors on the other hand are.

  Attenuated/weakened viruses still infect cells and go through normal protein-making machinery. Inactivated viruses and subunit/recombinant vaccines, however, just directly expose our immune system to the antigen(s) of the pathogen. mRNA/viral vector/attenuated all involve some degree of "code execution."

  > I don't think weakened viruses go through our protein-making machinery (aka code execution) Yes they do. They are live viruses, and they attack cells and hijack their protein-making machinery for making more viruses. But the attenuated vaccine viruses are not capable of causing a severe disease, so in time the body's immune system cleans them out. https://en.wikipedia.org/wiki/Attenuated_vaccine https://en.wikipedia.org/wiki/Attenuated_vaccine
