The leaders of the world's 20 biggest economies should use a meeting this weekend in Rome to agree on how to transfer surplus Covid-19 vaccines to low-income countries, a group of former presidents and prime ministers has said.

In a letter to Italian Prime Minister Mario Draghi, one hundred former leaders and government ministers from around the world urged him to use the G20 summit to address what they said was an unfair distribution of vaccines, Reuters reported.

The group said the United States, European Union, Britain and Canada would be stockpiling 240 million unused vaccines by the end of the month, which these nations' military could immediately airlift to countries in greater need.

“It would be unethical for all these vaccines to be wasted when globally there are 10,000 deaths from Covid-19 every day, many of which could be averted,” said the letter.
