@3fc9a904: mRNA vaccines are a new type of vaccine that work by using a small piece of genetic material called messenger RNA (mRNA) to instruct cells in the body to produce a protein that triggers an immune response. This immune response helps the body recognize and fight off the virus that the vaccine is designed to protect against. mRNA vaccines have been shown to be highly effective in preventing COVID-19 and have been authorized for emergency use in many countries.
