In his first public remarks since Biden last Saturday was widely projected the winner, Trump said he expects a coronavirus vaccine to be available for the entire population as soon as April, amid a crush of new infections that has pushed daily case counts to record highs.
In broadcast remarks in the White House Rose Garden, Trump also appeared to acknowledge for the first time the possibility of an upcoming Biden administration, though he stopped short of conceding the race and did not mention his Democratic rival by name.
"Ideally, we won't go to a lockdown. I will not go, this administration will not be going to a lockdown," he said. "Hopefully the, the – uh – whatever happens in the future - who knows which administration will be. I guess time will tell."
Since the Nov. 3 election, Trump has persisted with unfounded accusations of widespread voting fraud. But while he has continued to make such claims on Twitter, he did not repeat them in his public remarks on Friday.
The last time Trump spoke - in the White House briefing room two days after the election - he said without evidence that if "legal" votes were counted he would "easily win" the election.
Biden solidified his victory over Trump on Friday after the state of Georgia went his way, leaving Trump little hope of reversing the outcome through legal challenges and recounts.
The Republican president said on Friday that he expects an emergency use authorization for Pfizer's vaccine "extremely soon."
Pfizer has said it expects to report required safety data next week and can then apply for an emergency use authorization.
The remarks came after Trump received an update on 'Operation Warp Speed,' an administration effort to turbocharge development of a vaccine.
Criticism of the administration's response to the virus, which has killed over 235,000 Americans, became a rallying cry for Democrats ahead of the elections.
