Prince Harry and Meghan Markle will serve as campaign chairs of the VAX LIVE concert, a May 8 global broadcast and streaming special that celebrates the COVID-19 vaccine.

Selena Gomez will host the event described as "the concert to reunite the world," as it aims to encourage "world leaders to step up to make sure vaccines are accessible for all so we can end the pandemic for everyone, everywhere."

In their role, the Duke and Duchess of Sussex will encourage the private sector to make donations to COVID-19 Vaccines Global Access (COVAX), which is a vaccine-sharing program co-led by the World Health Organization (WHO).

"Over the past year, our world has experienced pain, loss, and struggle—together. Now we need to recover and heal—together. We can't leave anybody behind," the couple said in a statement posted on their Archewell Foundation page.

"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," the statement continued.

It's almost time for #VaxLive! On May 8, join us, @SelenaGomez, Prince Harry and Meghan, Duke and Duchess of Sussex, @JLo, @FooFighters, @chrissyteigen and more for a show with an urgent message: everyone, everywhere deserves access to a COVID-19 vaccine.
