How The U.S.' 500B Donated Vaccine Doses Will Impact The Globe

The U.S. latest vaccine pledge means 250 million people in some of the poorest countries could be fully vaccinated. Experts say that's fantastic news.

President Biden's announcement the U.S. will donate half a billion doses of the Pfizer COVID-19 vaccine around the globe is the largest any single country has made so far.  "Even though 250 million is still only a small portion of the entire population that needs to be vaccinated in those countries, it will go a long way to vaccinate people above 65 years of age, as well as the front line workers like health care workers," said Richard Reithinger, vice president of global heath at RTI International.  It also further establishes the U.S. as a world leader in vaccine distribution at a time when some public health experts have called on wealthy nations to do more to help those outside their borders.
