White House Press Secretary Jen Psaki will hold a news briefing on Tuesday, March 2.
Watch the briefing live at 12:30 p.m. ET.
This follows word from a Biden administration official that drugmaker Merck will help produce rival Johnson & Johnson’s newly-approved coronavirus vaccine.
The announcement comes as the White House looks to speed the production of the single-dose vaccine. Officials have said J&J faced unexpected production issues with its vaccine and only produced 3.9 million doses ahead of its receiving emergency use authorization on Saturday. The company says it is on pace to deliver 100 million doses by the end of June.
Psaki also announced Tuesday that the federal government was increasing supply of vaccines to states next week to 15.2 million doses per week, up from 14.5 million previously. States will also receive 2.8 million doses of the J&J shot this week.
Facing questions about the company’s slipping delivery schedule, J&J Vice President Richard Nettles told lawmakers on Capitol Hill last week that the company had faced “significant challenges” because of its “highly complex” manufacturing process.
The assistance from Merck was expected to help J&J meet its production commitments and expand supply even further, but the administration did not immediately provide specifics.
Psaki said that an “across the administration effort” was required to get the two historic rivals to work together on the vaccines, even though conversations between the two companies have been going on for months.
“There’s a difference between conversations and it moving forward,” she said.
