There are renewed calls for a more global approach to tackling Covid, as cases surge in various countries around the world.
Dr. David Nabarro from the World Health Organisation, says fair vaccine distribution is vital to accelerate the end of the pandemic.
He worries that some leaders are too focused on their own countries, leaving poorer nations vulnerable.
Dr. Nabarro urges people to speak up and demand vaccine equity:
"We need every citizen in every country to stand up and say to their government, 'Look, as long as this virus is multiplying in different parts of the world, as long as it's capable of mutating, it's capable of causing much more suffering to our world. And the only way to deal with it is with a global approach, a global programme that gets vaccine to everybody'."
