The mRNA will enter the muscle cells and instruct the cells’ machinery to produce a harmless piece of what is called the spike protein.
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.
At the end of the process, our bodies have learned how to protect against future infection from the virus that causes COVID-19.
