IDK they used measles virus in the movie, but in mRNA they don't use virus at all. They just use lipid nanoparticle with mRNA, it can't replicate. It just delivers mRNA to cells and the mRNA is used by the cells as a boilerplate to manufacture some proteins. In case of SARS-COV-2 vaccine it's spike (s-protein), not the virus itself, not lipid particle protein RNA, just RNA for the spike alone. RNA is not stable, for our human proteins we constantly manufacture new RNA from DNA. So basically we send command to manufacture some spike proteins so that our immune system can learn to recognize and neutralize the spikes. The movie parallel is just on the surface but in reality it works differently. I'm not saying that you shouldn't start packing your zombie-apocalypse backpack though.
