What do you mean by this?
With mRNA some cells in your body are tricked into growing so they have some unique but supposedly harmless aspect of the virus, like the spikes. [0] The immune system encounters these cells, recognizes them as not right, terminates and communicates to the larger system to be on the lookout for the molecular markers it found. If traditional vaccine is a trial by fire, then mRNA is trial by flashlight. It simulates some aspects of the fire but not others.
Immunization by mRNA may be better, sufficient or worse than the traditional immunity from actual virus material. I don’t think anyone knows for sure yet but I do know enough big money is riding on mRNA that it may be made to look like the only right approach even if it is only one of several good approaches.

Until it wanes, which you don’t know when it does, so you take a booster until you get a breakthrough case because you aren’t immunized, you got a biological shortcut.
