Walgreens has unveiled the next commercial in its “This Is Our Shot” campaign designed to win over vaccine skeptics — and, of course, let viewers know that its stores will be administering the shots free of charge. Featuring John Legend, the ad emphasizes the need for vaccine equity.

The ad will air on Sunday, April 18, during NBC’s “Roll Up Your Sleeves” special, which is sponsored by Walgreens. The special is designed to raise awareness of the vaccination push and make a compelling case to the vaccine-hesitant and -skeptical. Personalities set to appear include President Biden, Barack and Michelle Obama, Lin-Manuel Miranda and Matthew McConaughey, who will interview Dr. Anthony Fauci.
