“The additional 3.7 million treatment courses are planned for delivery by early 2023,” the company announced.
The Defense Department announced on Dec. 13 that Pfizer was awarded a $1,959,999,848 contract for Paxlovid. “Work will be performed in New York, New York, with an estimated completion date of Dec. 31, 2028,” according to the Pentagon.
“Fiscal 2021 Coronavirus Preparedness Response and Relief Supplemental Appropriations Act funds in the amount of $1,959,999,848 were obligated at the time of the award. U.S. Army Contracting Command, New Jersey, is the contracting activity,” the announcement reads.
The United States has spent around $10.6 billion to order from Pfizer the first 20 million courses of Paxlovid—roughly $530 per treatment course. Pfizer said it has already delivered the 20 million treatment courses.
Under the new contract, the U.S. government is paying around the same amount per course.
The Biden administration has, for months, been seeking more funds from Congress to support purchasing more of the antiviral pill as well as other treatments and vaccine booster doses.
Paxlovid is currently available for free in the United States, where more than 9 million courses have been delivered to pharmacies, and patients have used over 6 million courses of the treatment, according to government data.
The treatment was authorized by the U.S. Food and Drug Administration (FDA) in December 2021 for use in those aged 12 and older who are deemed at risk of severe illness from COVID-19.
In a statement, Pfizer said that as of Nov. 30, it had shipped almost 37 million courses of Paxlovid to 52 countries around the world. This includes the 20 million courses it delivered to the U.S. government.
In Pfizer’s clinical trial, Paxlovid was shown to reduce hospitalizations and death by around 90 percent for those deemed at risk for serious disease who were unvaccinated.
Pfizer, in June, announced it would stop enrollment in a separate clinical trial for Paxlovid for patients at a standard risk of COVID-19—including vaccinated patients—after the latest results suggested the drug did not reduce symptoms or hospitalizations and deaths to a statistically significant degree.
That same month, Pfizer submitted an application to the FDA to seek full approval for Paxlovid to be prescribed for COVID-19 patients at high risk of severe disease. The FDA is set to decide on the application by February 2023, the company said.
The Centers for Disease Control and Prevention (CDC) had warned in late May that some people may experience a rebound in COVID-19 symptoms after taking Paxlovid—meaning they may experience symptoms again after having had their symptoms resolved or test positive for COVID-19 after having tested negative.
The CDC said at the time that the rebound may be unrelated to the pill and “may be part of the natural history of SARS-CoV-2” in some people, “independent of treatment with Paxlovid and regardless of vaccination status.”
