the random pieces of mrna floating around in your bodies cells creating spike proteins eventually break down then the pieces are re used by your body for other tasks.

This is the key difference between the actual virus and the 'vaccine' the part that causes it to self replicate is missing. The J&J uses the typical cold virus shell to bypass your bodies defenses, the other vaccines use a lipid fatty/flesh-foam that bubbles into your cells as a delivery mechanism.

If you google search for adeno virus, you will see there are 3 parts; spike, triangle pieces of shell, and the mrna inside.

the vaccines theoretically only make 1 /3 of the virus, the spike, they don't create the shell or more copies of the mrna.

however, if you catch a DIFFRENT cold, then I wonder what is going to stop the vaccine spikes your body is making from connecting up with and joining into a different virus you are infected with?

In the animal studies it wasn't until a year or more later when another season round of mutated normal viruses go around that the animals had cascade failures that lead to death.
