"We can't leave anybody behind. We will all benefit, we will all be safer, when everyone, everywhere has equal access to the vaccine," the Duke and Duchess of Sussex said in a release, "We must pursue equitable vaccine distribution, and in that, restore faith in our common humanity. This mission couldn't be more critical or important."

President Joe Biden, along with First Lady Dr. Jill Biden and Vice President Kamala Harris, will also be making an appearance at the star-studded show where they will be aiming to increase public confidence in vaccines through the White House's "We Can Do This" initiative.

The virtual show, which will be hosted by Selena Gomez and also feature musical performances by Jennifer Lopez, the Foo Fighters, Eddie Vedder, J Balvin, and H.E.R., will be streamed Saturday, May 8, at 8 p.m. ET on Global Citizen's official Youtube channel.
