U.S. To Buy, Share 500M More Pfizer Vaccine Doses

The U.S. had previously committed to share 80 million doses with other countries.

The U.S. is significantly increasing the amount of vaccine supply its plan to share with the rest of the world.  The Biden administration is reportedly buying 500 million more doses from Pfizer to donate to COVAX, the international effort that aims to help poorer countries get supply.  While a majority of the people in the U.S. are now vaccinated, just small fractions can say the same in Africa and parts of South Asia.
