G7 leaders have pledged to intensify co-operation on Covid-19 and increase their contribution to the Covax vaccine-sharing initiative.
In a joint statement released after a virtual summit on Friday, G7 leaders raised their overall commitment to $7.5bn (£5.3bn).
Wealthy countries are facing growing pressure to make sure lower-income nations get fair access to vaccines.
President Joe Biden has pledged $4bn in US aid to the fund.
An initial $2bn will be donated in 2021, with an additional $2bn coming over the next two years.
Germany pledged an additional $1.2bn with Chancellor Angela Merkel telling journalists: “I stressed in my intervention that the pandemic is not over until all people in the world have been vaccinated.”
Covax is co-led by Gavi, known as the Vaccine Alliance, the World Health Organization (WHO) and the Coalition for Epidemic Preparedness Innovations (CEPI).
WHO chief Tedros Adhanom Ghebreyesus said on Friday he was grateful for the new commitments but emphasised that more was needed to address the world’s vaccination imbalance.
“Vaccine equity is not just the right thing to do, it’s also the smart thing to do,” he said at the annual Munich Security Conference, also held virtually on Friday.
French President Emmanuel Macron is among world leaders calling for further action to address the world’s vaccine imbalance – saying Europe and the US should urgently send up to 5% of their supplies to developing nations.BBC
