Are mRNA Covid Vaccines Risky? Here’s What the Experts Say

Instead of introducing the body to an inactivated or weakened version of a virus or a piece of it, they temporarily turn the body’s cells into tiny vaccine-making factories. They do this using synthesized versions of something called messenger RNA, a molecule that normally carries genetic coding from a cell’s DNA to its protein-making machinery.

In this case, the mRNA instructs the body to make the spike protein that Sars-CoV-2 uses to enter cells.
