RNA vaccines

RNA vaccines use a small piece of genetic material called messenger RNA (mRNA) to instruct cells in the body to produce a protein found on the surface of a virus, such as the coronavirus spike protein. This triggers the immune system to recognize and respond to the protein, building immunity without causing illness. Unlike traditional vaccines, which often contain weakened or inactivated viruses, RNA vaccines directly deliver instructions for the body's cells to make the viral protein. They are developed quickly, are highly effective, and do not contain live viruses, making them a safe and adaptable tool for disease prevention.
