Officials said that while the U.S.-produced doses are ready, deliveries have been delayed due to U.S. and the recipient countries’ legal, logistical and regulatory requirements.
“What we’ve found to be the biggest challenge is not actually the supply — we have plenty of doses to share with the world — but this is a Herculean logistical challenge,” said White House press secretary Jen Psaki.
Psaki said shipments will go out as soon as countries are ready to receive the doses and the administration sorts out logistical complexities, including vaccination supplies like syringes and alcohol prep pads, cold-storage for the doses, customs procedures and even language barriers.
Psaki said she was not aware of how many doses would be shipped by the end of the month.
The excess doses are not needed in the U.S., where demand for vaccinations has plummeted in recent weeks as more than 177 million Americans have received at least one shot.
Earlier this month, Biden announced that on top of the 80 million, the U.S. was purchasing 500 million doses from Pfizer to donate globally over the coming year, with the first deliveries expected in August.
Biden initially committed to providing other nations with all 60 million U.S.-produced doses of the AstraZeneca vaccine, which has yet to be authorized for use in the U.S. but is widely approved around the world. The AstraZeneca doses have been held up for export by a weekslong safety review by the Food and Drug Administration.
Given declining domestic demand, Biden was expected to be able to meet the full 80 million commitment without the AstraZeneca doses. The White House unveiled plans earlier this month for the first 25 million doses for export from existing federal stockpiles of Pfizer, Moderna and Johnson & Johnson vaccines and some have already begun shipping.
On Monday, it revealed plans for 55 million more shots.
Through COVAX, the latest batch of doses will include about 14 million for Latin America and the Caribbean, including Brazil, Argentina, Colombia, Peru, Ecuador, Paraguay, Bolivia, Uruguay, Guatemala, El Salvador, Honduras, Haiti, Dominican Republic, Panama and Costa Rica; approximately 16 million for Asia for India, Nepal, Bangladesh, Pakistan, Sri Lanka, Afghanistan, Maldives, Bhutan, Philippines, Vietnam, Indonesia, Thailand, Malaysia, Laos, Papua New Guinea, Taiwan, Cambodia and the Pacific Islands; and about 10 million for Africa, with countries selected in concert with the African Union.
About 14 million doses will be shared directly with Colombia, Argentina, Haiti, Dominican Republic, Costa Rica, Panama, Afghanistan, Bangladesh, Pakistan, Philippines, Vietnam, Indonesia, South Africa, Nigeria, Kenya, Ghana, Cabo Verde, Egypt, Jordan, Iraq, Yemen, Tunisia, Oman, West Bank and Gaza, Ukraine, Kosovo, Georgia, Moldova and Bosnia.
