The US has purchased and will donate 500 million doses of Pfizer's Covid-19 vaccine worldwide as it seeks to be a key player in getting other nations vaccinated.
President Biden will announce the news at the G7 summit in Cornwall on Thursday, a person familiar tells CNN.
Around 200 million doses will go out in 2021 and 300 million will be distributed in the first half of 2022. Biden's top Covid-19 adviser Jeff Zients has been working on the deal for the last month, a person familiar said.
All doses will go through COVAX, the international vaccine initiative, and will go to 92 low and lower-income countries, in addition to the African Union.
