Maj. Gen. A.C. Roper, Deputy Commanding General, U.S. Army Reserve Command, receives his second injection of the COVID-19 vaccine at Fort Bragg, North Carolina, Feb. 1, 2021. Roper received the first dose of COVID-19 inoculation Jan. 11, 2001, ensuring 21 days passed between vaccinations. The Pfizer and Moderna vaccines work by using transient information carrying molecules (mRNA) to teach our cells to make a protein that triggers antibody formation to create an immune response in our bodies. The mRNA is synthetic, not extracted from actual viruses, and it does not enter or interact with your body’s own DNA.
