The decision comes as the administration works to ramp up production of J&J’s single-shot vaccine. Senior administration officials said Sunday the U.S. government would ship J&J’s entire inventory of 3.9 million doses this week, adding that supply would be “uneven” in the following weeks. Some 16 million more doses are expected by the end of the month.
Under the arrangement, Merck will dedicate two facilities in the U.S. to J&J’s vaccine, according to NBC. One will make the vaccine and the other will provide “fill-finish” services, when the vaccine is placed in vials.
Officials began scouring the country for additional manufacturing capacity after they realized in the first days of the administration that J&J had fallen behind in vaccine production, according to NBC. They soon sought a deal with Merck, which scrapped plans to develop its own Covid vaccine in January after a clinical trial showed its shots were ineffective.
J&J declined to comment to CNBC on the deal. In a statement, Merck said it “remains steadfast in our commitment to contribute to the global response to the pandemic and to preparing to address future pandemics.”
Biden is expected to make the announcement from the White House on Tuesday afternoon.
The Food and Drug Administration on Saturday authorized J&J’s vaccine for use in people 18 and older. Unlike Pfizer‘s and Moderna‘s vaccines, J&J’s one-dose regimen eliminates the need for patients to return for a second dose, and it can be stored at refrigerator temperatures for months.
By comparison, Pfizer’s vaccine needs to be stored in ultracold freezers that keep it between minus 112 and minus 76 degrees Fahrenheit, though the FDA recently allowed the company to store its vaccine for two weeks at temperatures commonly found in pharmaceutical freezers. Moderna’s vaccine needs to be shipped at 13 below to 5 degrees above zero Fahrenheit.
The New York Times first reported in January that unexpected manufacturing delays would lead to a reduced initial supply of J&J’s drug if it were given emergency authorization.
White House Chief Medical Advisor Dr. Anthony Fauci said last month he was “disappointed” with the number of doses initially expected from J&J, adding the federal government thought there would be “considerably more.” The New Jersey-based company has a deal with the U.S. to provide 100 million doses by the end of June.
“It may take until June, July and August to finally get everybody vaccinated,” Fauci told CNN on Feb. 16. “So when you hear about how long it’s going to take to get the overwhelming proportion of the population vaccinated, I don’t think anybody disagrees that that’s going to be well to the end of the summer and we get into the early fall.”
At the time, Biden’s Covid czar, Jeff Zients, said the federal government was doing “everything we can working with the company to accelerate the delivery schedule.”
This isn’t the first partnership between two drugmakers to help ramp up the vaccine supply.
In late January, French drugmaker Sanofi announced it would help fill and pack millions of doses of Pfizer’s two-shot vaccine in an effort to help meet demand. Moderna has a partnership with Swiss company Lonza, which produces most of the drug substances for the company’s vaccine.
The Biden administration has also said it is using the Defense Production Act to help ramp up supply of Pfizer’s vaccine.
