"At the Summit world leaders are expected to announce they will provide at least 1 billion coronavirus vaccine doses to the world through dose sharing and financing and set out a plan to expand vaccine manufacturing in order to achieve that goal," the official statement said.

Prior to the three-day meeting at the Carbis Bay hotel, UK Prime Minister Boris Johnson had called his fellow G7 leaders to commit to vaccinate the entire world by the end of 2022, and to lead by example announced that the United Kingdom will donate at least 100 million surplus COVID-19 vaccine doses within this year.

"As a result of the success of the UK’s vaccine programme we are now in a position to share some of our surplus doses with those who need them. In doing so we will take a massive step towards beating this pandemic for good," Johnson was quoted as saying in the official statement.

According to the UK government, the first batch of 5 million doses will be donated by the end of September and a further 95 million within the next year, including 21 million more by the end of 2021.

Eighty percent of the 100 million doses will go to the World Health Organization-led COVAX vaccine distribution facility and the remainder will be shared bilaterally with countries in need.

The UK, which is aiming for all its adult population to have been offered a jab by the end of July, said that vaccines for donation will be drawn from across the UK’s supply of Oxford/AstraZeneca, Pfizer/BioNTech, Janssen, Moderna and others.

On Thursday, the US announced that it will donate half a billion Pfizer vaccines against the coronavirus to more than 90 lower income countries that are expected to get their first shipments in August.
