Trump administration officials passed when Pfizer offered in late summer to sell the U.S. government additional doses of its Covid-19 vaccine, according to people familiar with the matter. Now Pfizer may not be able provide more of its vaccine to the United States until next June because of its commitments to other countries, they said…

Asked if the Trump administration had missed a crucial chance over the summer to snap up more doses for Americans, a spokeswoman for the Department of Health and Human Services said, “We are confident that we will have 100 million doses of Pfizer’s vaccine as agreed to in our contract, and beyond that, we have five other vaccine candidates.”

In a statement, Pfizer said that “any additional doses beyond the 100 million are subject to a separate and mutually acceptable agreement,” and that “the company is not able to comment on any confidential discussions that may be taking place with the U.S. government.”
