Trump administration refused offer to buy millions more Pfizer vaccine doses

Decision could delay the delivery of a second batch until the manufacturer meets its orders for other countries

The Trump administration passed up a chance last summer to buy millions of additional doses of Pfizer's coronavirus vaccine, a decision that could delay the delivery of a second batch of doses until the manufacturer fulfills other international contracts.

The revelation, first reported by the New York Times and confirmed to the Associated Press on Monday, came a day before Donald Trump aimed to take credit for the speedy development of forthcoming vaccines at a White House summit.
