Across the state, health departments are beginning to open up COVID-19 vaccine clinics to children 12 and older. That comes on the heels of the CDC's announcement Wednesday that it endorses the use of the Pfizer vaccine for that age group. Dr. Sean O'Leary is a professor of pediatrics at the University of Colorado Anschutz Medical Campus and an infectious disease specialist. He works closely with the CDC's committee that recommended the approval of Pfizer's COVID-19 vaccine for kids 12 and over.
