Biden: U.S. will buy and donate 500M more COVID-19 vaccine doses for the world

President Biden will announce Wednesday the U.S. is purchasing an additional 500 million doses of the Pfizer-BioNTech coronavirus vaccine to give to the rest of the world, bringing its total commitment to more than 1 billion shots.

Mr. Biden will also press other global leaders to “step up” and do more during a COVID-19 summit that he is hosting on the sidelines of the U.N. General Assembly, according to a senior administration official.

“For every one shot we have administered in this country to date, we are now donating three shots to other countries. One shot here today, three shots committed for the world,” the official told reporters. “No other country, or group of countries, have come close to that.”
