In fact, the vaccine is cleared after a couple of weeks leaving only your boosted immune response. No one who knows what long-term effects some people may have to that - but they'll be long-term and no one's willing to wait for 2 years for that (although phase 4 trials will continue that long)

The mRNA vaccines do technically prompt your body produce virus protein. That said, the proteins don't have the ability to infect your cells. It's similar to how we inject dead flu cells to develop flu immunity before the body is faced with active viral cells.

Yep, a small portion of mRNA that codes for the receptor binding domain on the spike protein of the virus (the part that actually sticks to your cell when being infected) - that small portion of mRNA that does nothing by itself is encased in a nano lipid particle (think small small small oil droplet). Since our cells are made of lipid on the outside - imagine oil droplets in water and how they interact with each other. So the nanoparticles fuse with our cell membranes and that tiny portion of mRNA is introduced into the cell where it's turned into binding domain proteins, not replicated, by our cells ribosomes. Since it's recognized as foreign - specialized molecules called MHC will grab it and displayed on the cell surface. From there our immune system takes over, sees the Protein that's been produced, and start producing antibodies against it. That is a nutshell is how it works.
