COVID-19 vaccines help our bodies develop immunity to the virus that causes COVID-19 without actually getting the illness. Unlike other vaccines which put a weakened or inactive germ into our bodies, mRNA vaccines, when injected, instruct the cells how to make a protein that triggers an immune response. The immune response will produce antibodies that will protect our bodies from getting infected if the real virus enters our bodies. This is the first time that mRNA vaccines have received an emergency use authorization, but researchers have been working with mRNA for decades. These vaccines can be developed in a laboratory using readily available materials, which can result in a quicker release of the vaccine as compared to other traditional types of vaccines. As soon as necessary information about coronavirus became available, scientists started working on the vaccine.
