How Do mRNA Vaccines Work?

Published on January 31, 2022

Rupali Limaye, PhD, of Johns Hopkins Bloomberg School of Public Health presents a kid-friendly explanation of the science behind mRNA vaccines, specifically, the COVID-19 vaccine.

The mRNA Vaccine Process

Dr. Limaye begins with explaining mRNA. Messanger RNA sends a message to cells to develop a spike protein, displayed on the surfaces of cells.  Soon thereafter, the cells will release these spike proteins. Once the body realizes that the protein is a foreign mass, the immune system is triggered to produce antibodies. Antibodies mimic an infection in the body, training the immune system to prepare the appropriate response. This helps our bodies fight off a future COVID-19 infection.

Dr. Limaye continues to touch on proper dosage and potential side effects, explaining it as an immune response.
