Prince Harry pens letter on behalf of late mother Princess Diana on World AIDS Day

The Duke of Sussex, Prince Harry spoke on behalf of his late mother Princess Diana in his letter on World AIDS Day. The royal called the world to join in the cause that was so close to her heart.

In his letter, Harry, 37, asked world leaders and his followers to join a movement to ensure that science for HIV and COVID-19 reaches all who need it most.

On Wednesday, he penned down a letter and narrated a film in honor of World AIDS Day to bring awareness to the fight against HIV and AIDS. Harry’s mother, the late Princess of Wales had also put efforts to break the stigma experienced by people affected by HIV and AIDS.

"We honour those whose lives have been cut short and reaffirm our commitment to a scientific community that has worked tirelessly against this disease," Harry writes in a letter to Winnie Byanyima, Executive Director UNAIDS, and Dr. Tedros Adhanom Ghebreyesu, the World Health Organization's Director-General.

"My mother would be deeply grateful for everything you stand for and have accomplished. We all share that gratitude, so thank you," he continues.

Harry, who has twice undergone public testing for HIV (including alongside Rihanna in Barbados in 2016) to encourage people to be tested, spoke out at the special UNAIDS conference on Wednesday (December 1).

"It is striking to now see the world's leading AIDS activists are also leading the call for COVID-19 vaccine equity," his letter continues. "Vaccinating the world is a test of our moral character and we are experiencing a spectacular failure when it comes to global vaccine equity. Similar to the AIDS crisis, we've yet again revealed over the past year, that the value of life depends on whether you were born and/or live in a rich nation, or a developing country."

In the accompanying film, Harry also narrated, "This is a story about how corporate greed and political failure have prolonged both pandemics and what we can do to stop it."
