“People have lost faith in the ability of the vaccine to work,” Biden told CNN in an interview set to air later on Thursday.

Fauci, director of the National Institute of Allergy and Infectious Diseases and a member of President Donald Trump’s coronavirus task force, met with Biden’s advisers on the pandemic earlier in the day. In the interview, Biden said he asked Fauci to stay on as a chief medical adviser.

Trump and the Republican National Committee said on Thursday they had raised $207.5 million since the Nov. 3 election. Trump has urged supporters to send money to finance his legal efforts to overturn his loss to Biden. The efforts have so far proved fruitless.

Trump at times has criticized Fauci’s insistence on aggressive measures to combat the COVID-19 pandemic, which has now claimed 273,000 U.S. lives.

U.S. deaths from the coronavirus pandemic have surged past 2,000 for two days in a row as the most dangerous season of the year approaches. Nearly 200,000 new U.S. cases were reported on Wednesday, with hospitalizations approaching 100,000 patients.

Pfizer Inc’s vaccine has already been approved by regulatory authorities in Britain, while the U.S. Food and Drug Administration plans to decide whether to do so on an emergency basis after an advisory panel meeting on Dec. 10. Vaccines could be distributed in the United States almost immediately afterward.

Fauci was critical, however, of the approval process in the UK. “They kind of ran around the corner of the marathon and joined it in the last mile,” he told CBS News. “They really rushed through that approval.” He later apologized, however, for his critique, telling the BBC that he meant “no judgment” of the British process.

Biden’s remarks to CNN came after three former presidents - Bill Clinton, George W. Bush and Barack Obama - said they would publicly get the coronavirus vaccine as a way to demonstrate its safety.

As part of his response effort, Biden will tap former Obama administration official Jeffrey Zients as his White House coronavirus coordinator, a Biden ally told Reuters.

Politico reported that Biden adviser Vivek Murthy would return to his role as surgeon general, a post he held under Obama, but with a broader portfolio as the pandemic rages through the country.

Politico also said Marcella Nunez-Smith, co-chair of Biden’s COVID-19 advisory board, would play a key role in the incoming administration’s pandemic response, focused on disparities.

Zients, a wealthy businessman who has moved between the public sector and corporate America, will oversee the mammoth and unprecedented operation to distribute hundreds of millions of doses of the new vaccine in the United States, coordinating efforts across multiple federal agencies.

In recent weeks, Zients has served as a pandemic liaison of sorts with governors and state officials, frequently joining calls to share data and discuss concerns, according to two sources familiar with the calls.

Biden said that Brian Deese, who helped lead Obama’s efforts to bail out the automotive industry during the 2009 financial crisis, would head the National Economic Council.

Trump’s push to reverse the results of the election saw its latest setback on Thursday when Wisconsin’s Supreme Court declined to take up a case filed against election officials in the battleground state.
