UK PM Boris Johnson said that the world is looking to the G7 leaders to move beyond the sometimes "nationalistic" and selfish initial responses to the pandemic.
He sayid this weekend, leaders have pledged over one billion doses of the vaccines to poorer countries - either directly or via the Covax sharing scheme - including 100 million from the UK, reports the BBC.
It is "another big step towards vaccinating the world," said Johnson.
He also mentioned the role of the Oxford/AstraZeneca jab - "the world's most popular vaccine".
It is popular of course because it's being sold at cost to the world, said Johnson, calling it "an act of generosity" from AstraZeneca.
96% of the vaccines delivered by Covax have been Oxford/AstraZeneca, he added.
