US President Joe Biden to give 500 million more covid-19 vaccines to the world

US President Joe Biden has pledged to donate 500 million more doses of the Pfizer vaccine to developing nations from next year.

He made the pledge at a virtual Covid-19 summit on the sidelines of the UN General Assembly, promising an "arsenal of vaccines".

“To beat the pandemic here, we need to beat it everywhere,” Biden said. He added that with the new commitments, “For every one shot we’ve administered to date in America, we have now committed to do three shots to the rest of the world.”

The World Health Organisation has set a minimum target of 40% vaccine coverage in every country by the end of 2021.Health experts say some 11 billion doses are required to vaccinate at least 70% of the global population.

But according to data from the University of Oxford, only 2% of people in low-income countries have had their first dose, compared to many high-income countrieswho have now given at least one shot to more than half their populations.

In June, members of the G7 - Canada, France, Germany, Italy, Japan, the UK and the US - pledged to donate one billion doses to poor countries over the next year.

Biden pledged 580m at the time, of which the US has delivered only 160m so far.
