"You will see him invoking the Defense Production Act," Dr. Celine Gounder, a member of Biden's Covid-19 advisory board, said during an interview on CNBC's "Squawk Box." "The idea there is to make sure the personal protective equipment, the test capacity and the raw materials for the vaccines are produced in adequate supply."
The wartime production law, which allows the president to compel companies to prioritize manufacturing for national security, could help the U.S. secure components and specialized products that manufacturers need to produce the Covid vaccines. Biden's team has been weighing whether to invoke the law for vaccine production, NBC News reported last week.
The New York Times reported last week that Pfizer, which manufactures one of the two Covid vaccines approved for emergency use in the U.S., began asking the Trump administration in September to help the pharmaceutical giant obtain some supplies needed for production but was disappointed by a lack of response.
Representatives for the White House did not return CNBC's request for comment.
For weeks, the U.S. had been negotiating with Pfizer to secure additional vaccine doses on top of the original 100 million doses that the U.S. had locked in. Last week, Pfizer said it had struck a deal to supply an additional 100 million doses to the U.S by July.
The Times, citing people familiar with the negotiations, reported that as part of the deal, the U.S. government agreed to invoke the Defense Production Act to "help Pfizer get better access to around nine specialized products it needs to make the vaccine."
Representatives for Pfizer did not return CNBC's request for comment.
A representative for the Department of Health and Human Services said in a statement to CNBC that the Trump administration has already invoked the Defense Production Act 18 times in relation to vaccine production.
"Efforts to expand the manufacturing capacity across the nation's pharmaceutical production base include: enhancing plants and production lines with specialty tooling and staff; optimizing the supply chain of raw materials; investing in production of supplies such as glass vials and syringes; and scaling up fill/finish lines," the spokesperson said.
Through Operation Warp Speed, the U.S. government has invested in six companies' efforts to bring a Covid vaccine to market, but only two have been authorized by the Food and Drug Administration: Pfizer's and Moderna's. One concern of invoking the Defense Production Act for Pfizer is that it will favor the manufacturer over others, giving Pfizer unfair access to necessary vaccine components.
Gounder did not explain how or whether Biden intends to equitably use the law. Her comments come as she and other Biden advisors cast doubt on the vaccination timeline laid out by President Donald Trump and his health officials.
Fewer than 2 million people have received the vaccine as of Saturday, according to the Centers for Disease Control and Prevention. That's far below the administration's previously stated goal of vaccinating 20 million people before the end of the month, though Adm. Brett Giroir, assistant secretary of health, has said there are delays between the states and the CDC data.
Trump's coronavirus vaccine czar, Moncef Slaoui, told reporters during a press briefing on Wednesday that the ramp-up of immunizations was going slower than expected.
"We're here to help the states to accelerate appropriately," he said, adding the goal of 20 million vaccinations is "unlikely to be met."
