what happens to the vaccine after the mRNA is processed by the ribosome?

So obviously i understand a bit of how the covid19 vaccine works, but what happens to the strands of mRNA after the ribosome "reads" it? Does it just float around in the cell or does it get broken down, or something else?

It is broken down. Your body is constantly sending mRNA to the ribosomes and there are enzymes in the cytoplasm there ready to catch it and break it down. That way the ribosomes aren’t forever making the same proteins over and over. This has actually been the biggest hurdle in developing mRNA treatments and vaccines, getting them to stick around long enough to be read by a ribosome before the enzymes break it down!
