WASHINGTON (AP) � The U.S. will buy 500 million more doses of the Pfizer COVID-19 vaccine to share through the COVAX alliance for donation to 92 lower income countries and the African Union over the next year, a person familiar with the matter said Wednesday.
President Joe Biden was set to make the announcement Thursday in a speech before the start of Group of Seven summit.
According to the person, 200 million doses � enough to fully protect 100 million people � would be shared this year, with the balance to be donated in the first half of 2022.
