The Duke and Duchess of Sussex celebrated their son Archie’s birthday on May 6 by sharing a new photo of the now two-year-old.

In the photo, Archie has his back to the camera while holding a large bunch of balloons.

Fans of the royal couple haven’t seen a photo with the toddler’s face since his first birthday, when Meghan released a video of her reading a book to Archie.

For his second birthday, the couple are asking fans to donate to vaccine equity.

The Duke and Duchess of Sussex said they are “deeply touched” by “the warmth and support for our family”, thanking fans for their donations to charities in Archie’s name.

“Many of you donate to charities on his behalf, and mark the occasion by giving back or doing an act of service – all through the goodness of your hearts,” they said in a statement on their Archewell website.

Having recently been campaign chairs for the Global Citizen Vax Live concert, they told fans that a US$5 (AUD$6.45) donation would pay for a single dose and that each donation would be matched by other organisations to increase the number of doses available for people in developing countries.

“We cannot think of a more resonant way to honour our son’s birthday,” they said.

“If we all show up, with compassion for those we both know and don’t know, we can have a profound impact. Even a small contribution can have a ripple effect,” the couple continued.

“Together we can uplift, protect, and care for another.”

Though it is tradition for the royals to release a new portrait to mark royal children’s birthdays, it remains to be seen whether the couple will uphold the tradition after their departure from the British Royal Family last March.
