Biden’s White House on Monday announced a list of countries that would receive 55 million doses, after previously detailing the first tranche of 25 million. In total, three-quarters of the 80 million will be sent through COVAX, a World Health Organization-backed vaccine procurement effort.

The announcement, however, dials back the initial US commitment. Biden once said he’d “send” 80 million doses by the end of June, and is now pledging only to “allocate” them by then, suggesting shipments will stretch into July or beyond.

Of the 55 million, approximately 41 million will go to COVAX. The remaining 14 million will be shipped bilaterally.
