The Advisory Committee on Immunization Practices, an external group of medical experts that advises the Centers for Disease Control and Prevention, is due to vote Tuesday on who will be the first to receive the coronavirus vaccine.
Scientists and infectious disease experts have discussed who will get the first shots and how the vaccine will be distributed. Medical experts have said health workers should get it first, followed by vulnerable Americans, including the elderly, people with pre-existing conditions, and key workers.
