President-elect Joe Biden continued to encourage Americans to get the Covid-19 vaccine, which he called "one of the biggest operational challenges the United States has ever faced."
"I got a chance to thank all of those nurses and docs at Christiana hospital for what they've been putting up with what they've been doing for so long. I look forward to the second shot, and I have absolute confidence in the vaccine. But we're in short supply. Taking the vaccine from a vial into the arm of millions of Americans is one of the biggest operational challenges the United States has ever faced," Biden said moments ago during a year-end message and news conference in Wilmington, Delaware.
Biden added: "And we're going to take many more months for that to happen. In the meantime, this pandemic rages on. Experts say things are going to get worse before they get better."
Some context: Biden received his first dose of the Pfizer and BioNTech coronavirus vaccine on live television Monday afternoon and reassured Americans of the vaccine's safety.
The shot, which Biden received in his left arm, was administered at ChristianaCare's Christiana Hospital in Newark, Delaware, by Tabe Mase, who is a nurse practitioner and the head of employee health services at the hospital, according to the Biden transition team.
"We owe these folks an awful lot," Biden said, thanking those involved in the vaccine's development and distribution and front-line health care workers.
Biden said the Trump administration deserved "some credit" for Operation Warp Speed, the federal government's vaccine program, and their role in making coronavirus vaccinations possible.
"I also think that it's worth saying that this is, is great hope. I'm doing this to demonstrate that people should be prepared, when it's available, to take the vaccine. There's nothing to worry about. I'm looking forward to the second shot; so is Jill," Biden said.
