mRNA Vaccines
mRNA vaccines are a type of vaccine that teach our cells how to recognize and fight off viruses. Instead of using a weakened form of a virus, mRNA vaccines use a small piece of genetic material (messenger RNA) that contains instructions for making a harmless part of the virus, like its spike protein. When the vaccine is injected, our cells produce this protein, and the immune system learns to recognize it. If the real virus later enters the body, the immune system is prepared to respond quickly, helping to prevent illness. Examples include the Pfizer-BioNTech and Moderna COVID-19 vaccines.

mRNA vaccines are a new type of vaccine that use messenger RNA (mRNA) to teach our cells how to fight infections. Unlike traditional vaccines, which often use weakened or inactivated viruses, mRNA vaccines contain a small piece of genetic material that instructs our cells to produce a harmless piece of the virus, prompting an immune response. This prepares our immune system to recognize and combat the real virus if we're exposed. They have been pivotal in controlling diseases like COVID-19 and are seen as a breakthrough in vaccine technology.
