Very very simplified: Basically, you have a blob of fat that the mRNA sits in. The fat sticks to the cell, merges with the cell membrane and the mRNA pokes into the cell. It's not a modified virus, it's a much simpler structure but it has a similar mechanism. It's much simpler in that it can't replicate itself or do much else. It's literally just the code for a protein that's found on the surface of the covid virus, in a blob of fat. That's for the BioNTech/Pfizer vaccine. Other vaccines, such as the Oxford/AstraZeneca one do use a modified virus.

So no spike protein needed? Safe to assume that in time these will evolve into new forms of fat-embeded rna virus which no living being has immunity to?

  The mRNA contains the spike protein or at least a sufficient part of it for the immune system to recognize, as well as other genes.

  No, they won't. They can't survive for long enough inside the body, and are even less durable outside.
