The livestreamed event, happening May 8, will be hosted by actress and musician Selena Gomez. The live audience will consist of vaccinated frontline and essential workers.

The Sussexes are expected to deliver a message on the importance of global vaccine equity, according to a press release. The pair have also been leading a coordinated effort to raise funds across the private sector for the vaccine-sharing program COVAX, which has wealthy governments share excess doses and encourages pharmaceutical companies like Moderna to make vaccines available at not-for-profit prices.

“Over the past year, our world has experienced pain, loss, and struggle—together. Now we need to recover and heal—together,” Harry and Meghan said in a statement. “We can’t leave anybody behind. We will all benefit, we will all be safer, when everyone everywhere has equal access to the vaccine. We must pursue equitable vaccine distribution, and in that, restore faith in our common humanity. This mission couldn’t be more critical or important.”
