The United States did not buy enough of the Pfizer vaccine this summer when Pfizer asked how much did the US want.
Pfizer has told the Trump administration it cannot provide substantial additional doses of its
coronavirus vaccine until late June or July because other countries have rushed to buy up most of its supply, according to multiple individuals familiar with the situation.
That means the U.S. government may not be able to ramp up as rapidly as it had expected from the 100 million doses of the Pfizer vaccine that it purchased earlier this year, raising questions about whether it can keep to its aggressive schedule to vaccinate most Americans by late spring or early summer.
Trump administration officials denied there would be availability issues in the second quarter, citing other vaccines in the pipeline -- most immediately, Moderna's, also expected to be approved in coming weeks. Both vaccines are two-dose regimens, so the 100 million doses purchased of each would cover 50 million people each.
Last summer, Pfizer officials had urged Operation Warp Speed to purchase 200 million doses, or enough of the two-shot regimen for 100 million people, according to people knowledgeable about the issue who spoke on the condition of anonymity because they weren't authorized to discuss the situation. But the Warp Speed officials declined, opting instead for 100 million doses, they said. The New York Times first reported that federal officials passed on the opportunity when Pfizer offered to sell more doses.
