The Biden administration is supporting Pfizer Inc.’s move to begin exporting U.S.-made doses of its coronavirus vaccine, as the White House starts to open up production for shot-starved nations abroad.

"We are glad to see that they are working with other countries to help them meet their supply needs,” Jeff Zients, President Joe Biden’s COVID-19 response coordinator, told Bloomberg News in a statement. He said the company is ahead of schedule in its commitments to supply the U.S.

The governments of Mexico and Canada said last week that they expected to begin receiving doses of Pfizer’s vaccine from the U.S., the first time the company’s American-made shots are known to have been delivered to any buyer other than the American government.
