Meghan and Prince Harry are joining the 24-hour-long global broadcast of Global Citizen Live, an event calling for vaccine equity to end the Covid crisis across the world. The Duke and Duchess of Sussex will take part in the live event starting on Saturday at 5pm and broadcasted, among others, by BBC One.

       The live will be broadcasted from Great Lawn in New York City’s Central Park - a city Meghan said to love in a post shared on her now-defunct lifestyle blog, The Tig.

       News of Meghan and Prince Harry's attendance at the event was shared by Global Citizen, an organisation working towards defeating poverty worldwide and safeguarding the environment from the climate crisis.

       The organisation described in its statement the Duke and Duchess of Sussex as "two of the strongest voices on vaccine equity" and recalled the previous support it received from the couple.

       The live event aims at pressuring G7 countries and the European Union to share at least one billion COVID-19 vaccines with developing countries.

       It will also support calls for a waiver on COVID-19 vaccine intellectual property rights.

       Finally, the campaign is also calling on Pfizer, BioNTech, and Moderna to share mRNA technology with the new World Health Organization-backed transfer hub based in South Africa.

       Meghan and Harry have championed the cause of vaccine equity on multiple occasions over 2021.

       In May, they launched on Archewell.com a fund-raising appeal linked to their son Archie Harrison's second birthday, which ended up raising some ￡3.5million for Gavi, the Vaccine Alliance.

       They also became co-chairs of Global Citizen’s VAX LIVE: The Concert to Reunite the World during the same month.

       The live event called on world leaders, corporations, and philanthropists to ensure vaccines are available to all.

       As co-chair Meghan and Harry also penned an open letter to CEOs of major pharmaceutical companies calling on them to urgently share COVID-19 vaccines with the world’s poorest countries.

       The Duke took part in the live event, during which he thanked healthcare workers for their continuous efforts and described the vaccine against coronavirus as a "basic right for all".

       Meghan, who was not on stage as she was pregnant at the time, appeared on video during the concert to highlight how vaccine equity would not just help return to normalcy and rebuild the economy but would also "go further, and rapidly advance the conditions, opportunity, and mobility for women everywhere."

       The Duke and Duchess of Sussex went on parental leave following the birth of their daughter Lilibet 'Lili' Diana in early June.

       However, Prince Harry stepped out of his break from the public eye to remotely take part in the GQ Men of the Year Awards in early September.

       As he delivered the Heroes of the Year Award to the team behind the Oxford/AstraZeneca vaccine, he spoke once again about the importance of a fair distribution of Covid vaccines around the world, clearly stating the pandemic will end only when everybody gains access to the jab regardless to their wealth or country of birth.

       His speech was hugely appreciated by Dr Catherine Green and Professor Dame Sarah Gilbert, who led the Oxford team of scientists.

       Following the awards, Dr Green told People magazine: "So suddenly Prince Harry is on stage and he said all of the things we wanted to say about the essential necessity to get the vaccine to the world for people irrespectively of their ability to pay. Really important message."

       Dame Sarah added: "Yes, because we are not going to be safe until everyone is safe, and it is really important to get the vaccine to everyone around the world."

       If the Duke and Duchess attend Global Citizens Live in person, it will be their first joint public event in the Big Apple.

       Since joining the Royal Family in 2018, Meghan has been spotted a handful of times in the city.

       In February 2019, she travelled across the pond to attend a baby shower in her honour as she was expecting Archie.

       The party was attended, among other celebrities, also by tennis champion Serena Williams and Amal Clooney.

       A few months later, she was spotted among the crowd at the US Open final to cheer for her friend Williams.
