The first COVID-19 vaccines to reach the market are likely to be messenger RNA (mRNA) vaccines. According to the Centers for Disease Control and Prevention, mRNA vaccines work by teaching cells in the body how to make a protein that triggers an immune response. Unlike many vaccines that use weakened or inactivated forms of a virus, mRNA vaccines do not use the live virus that causes COVID-19.

Gregory A. Poland, M.D., an infectious diseases expert and head of Mayo Clinic's Vaccine Research Group, explains how mRNA vaccines work, gives a status update on the pandemic and answers listener questions.
