COVID vaccines shots are going into lots of arms. The CDC says nearly half off all adults in the U-S have received at least one dose. It also says an average of 3-point-2 million doses are being administered each day.

Dr. George Rutherford is an epidemiologist & director of the Division of Prevention & Public Health at UC San Francisco's School of Medicine.  As we continue the battle against COVID-19, the main focus these days are variants.
