Not exactly. The mRNA fragments are instructions to build pieces of the virus. Your cells execute the mRNA instructions, build virus fragments, and _then_ the immune system notices all these unknown fragments and learns how to destroy them.

That'll trigger CD4+ and CD8+ T-cells to also go into action. Some of the cells will be transported to lymph nodes and the gut for processing by the immune system. CD8+ cells will learn to recognize the MHC-antigen on the surface of cells and kills the "infected" cells. Then next time around B-cells and T-cells are primed from all this target practice and its a lot easier, even if the neutralizing antibodies wane.
