President Biden Unveils Global Vaccination Strategy

He's urging other countries to contribute to the global vaccine supply after the U.S. pledged another 500 million doses to COVAX.

President Biden has announced a new commitment to share more COVID vaccines with the rest of the world over the next year. He said the U.S. is buying 500 million more doses of the Pfizer vaccine to donate to countries struggling to get their hands on shots. That's in addition to the Biden administration's pledge to share 80 million shots by the end of this month.
