So, what I'm saying in summary, is that after our cells make copies of the protein, the enzymes in the body degrade the mRNA and dispose of it. The cell breaks down the mRNA into harmless pieces and gets rid of it. If people are infected, they can shed virus via. Since our cells are continuously producing proteins, mRNA is broken down fairly quickly by normal body processes. What is viral shedding anyway People can shed (or release) virus after a viral infection, such as SARS-CoV-2, the virus that causes COVID-19. It doesn't enter the nucleus of the cell and it does not alter DNA. The idea is that someone who has been vaccinated is shedding spike protein to those around them who have not been vaccinated. It stays in the cytoplasm, attaches to the ribosome, passes on its message, and then gets destroyed. There have been rumors of vaccine shedding causing side effects to people who have not been vaccinated. Our B lymphocytes and T lymphocytes, both types of white cells, remember how to fight the virus that causes COVID-19 if we're ever infected in the future.įortunately, mRNA has a very short life span. The body's immune system recognizes the spike protein shouldn't be there, so it produces the protection against it. That protein is unique to the SARS-CoV-2 virus, but it's harmless by itself. As you know, the mRNA translates the information needed to produce the SARS-CoV-2 spike protein, that protein that's on the surface of the virus.

What Stops the Body from Continuing to Produce the COVID-19 Spike Protein after Getting an mRNA Vaccine?
