Like all vaccines, mRNA vaccines benefit people who get vaccinated by giving them protection against diseases like COVID without risking the potentially serious consequences of getting sick. However, researchers have been studying and working with mRNA vaccines for decades.

However, for a booster dose , the booster dose product does not need to match the product used for the primary series. They do not affect or interact with our DNA in any way. 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. Facebook Twitter LinkedIn Syndicate.

Last Updated Jan. The virus assembles new copies of itself and spreads to more parts of the body and—by way of saliva, sweat, and other bodily fluids—to other humans. One of the reasons viruses are such a challenge is that they change and mutate in response to drugs.

That means novel virus treatments and vaccines have to be created each time a new strain of virus presents itself. Traditional vaccines against viruses like influenza inject inactivated virus proteins called antigens. This mRNA provides cells with instructions to produce the virus antigen themselves. Since the SARS-CoV-2 virus spike protein is foreign to our bodies, our bodies will then make antibodies that inactivate the protein. An RNA-based vaccine therefore acts as a code to instruct the body to make many copies of the virus protein—and the resulting antibodies—itself, resulting in an immune response.

Unlike more traditional vaccines, RNA-based vaccines are also beneficial in that they eliminate the need to work with the actual virus. Adam Fenster. Maquat has been studying RNA since and was part of the earliest wave of scientists to realize the important role RNA plays in human health and disease.

Recap Unlike traditional vaccines that contain a weak or inactive form of a virus, messenger RNA mRNA vaccines instruct cells in your body to build a protein similar to the virus.
