One of the most innovative ways to protect ourselves from diseases is by using mRNA vaccines. These vaccines work by using a molecule called messenger RNA (mRNA) that carries a genetic instruction to our cells. The instruction tells our cells to make a protein that looks like the one on the surface of the virus or bacteria that causes the disease. When our immune system sees this protein, it learns to produce antibodies that can fight off the real infection. mRNA vaccines are very convenient because they do not contain any part of the virus or bacteria, so they cannot make us sick. They are also easy to make and modify, which means they can be quickly updated to match new variants of diseases. mRNA vaccines have been proven to be very effective and safe against COVID-19, the disease caused by the new coronavirus, and they could be used for many other diseases in the future.
