Understanding mRNA COVID-19 Vaccines

Facts About COVID-19 mRNA Vaccines

COVID-19 mRNA vaccines cannot give someone the virus that causes COVID-19 or other viruses.

mRNA vaccines do not use the live virus that causes COVID-19 and cannot cause infection with the virus that causes COVID-19 or other viruses.

They do not affect or interact with our DNA in any way.

mRNA never enters the nucleus of the cell where our DNA (genetic material) is located, so it cannot change or influence our genes. The mRNA and the spike protein don’t last long in the body.

Our cells break down mRNA and get rid of it within a few days after vaccination.

Scientists estimate that the spike protein, like other proteins our bodies create, may stay in the body up to a few weeks.

How mRNA Vaccines Work

To trigger an immune response, many vaccines put a weakened or inactivated germ into our bodies. Not mRNA vaccines. Instead, mRNA vaccines use mRNA created in a laboratory to teach our cells how to make a protein—or even just a piece of a protein—that triggers an immune response inside our bodies. That immune response, which produces antibodies, is what protects us from getting infected if the real virus enters our bodies.

COVID vaccine

First, COVID-19 mRNA vaccines are given in the upper arm muscle. The mRNA will enter the muscle cells and instruct the cells’ machinery to produce a harmless piece of what is called the spike protein. The spike protein is found on the surface of the virus that causes COVID-19. After the protein piece is made, our cells break down the mRNA and remove it.
Next, our cells display the spike protein piece on their surface. Our immune system recognizes that the protein doesn’t belong there. This triggers our immune system to produce antibodies and activate other immune cells to fight off what it thinks is an infection. This is what your body might do to fight off the infection if you got sick with COVID-19.

At the end of the process, our bodies have learned how to protect against future infection from the virus that causes COVID-19. The benefit of COVID-19 mRNA vaccines, like all vaccines, is that those vaccinated gain this protection without ever having to risk the potentially serious consequences of getting sick with COVID-19. Any temporary discomfort experienced after getting the vaccine is a natural part of the process and an indication that the vaccine is working.

Messenger RNA (mRNA) Vaccines for COVID-19: How Do They Work?

When the vaccine is injected into the upper arm, the mRNA enters cells near the site of the injection and tells the cells to start making the same protein that is found in the COVID-19 virus. The immune system recognizes this protein and begins producing antibodies that can fight the virus if the vaccinated person is later infected.

None of the vaccines interact with or alter your DNA in any way, and therefore cannot cause cancer. MRNA is not the same as DNA and cannot be combined with DNA to change your genetic code. The mRNA is fragile and it delivers the instructions to your cells to make antibodies against SARS-CoV-2. The mRNA does not enter the nucleus of the cell — the part that contains your DNA. Therefore, there is no truth to the myth that somehow the mRNA vaccine could inactivate the genes that suppress tumors.

The COVID-19 vaccine does not expose you to the virus that causes COVID-19.
