US President-elect Joe Biden receives coronavirus vaccine on live television

In images carried live on television, Biden was seen with his sleeves rolled up and wearing a black mask as he got injected.

He was given the dose by nurse Tabe Mase, who is also the head of Employee Health Services at Christiana Hospital in Newark, Delaware.

"We owe these folks an awful lot," Biden said about the scientists and researchers.

The 78-year-old was given the vaccine developed by Pfizer and BioNTech.

"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," Biden said. The future First Lady Dr. Jill Biden received the shot before him.

Reportedly, Vice-President Kamala Harris and her husband, Doug Emhoff, will receive the vaccine dose next week.

When he takes office in January, Biden will face the mammoth challenge of providing respite to a country that has lost 326,772 to the deadly disease. The origins of coronavirus have been traced to China.

The incoming Democratic administration also has the responsibility to distribute vaccines to millions of Americans.

Till December 20, over 128,000 had received the doses of Pfizer's vaccine.

Biden told citizens that the vaccine roll-out is in its initial phases, adding that the road ahead is a long one. "It's going to take time," he said.

In the meantime, he urged Americans to honor the precautions, like wearing masks, washing hands, maintaining distance, and not traveling until it is absolutely necessary.

"We're still in the thick of this," he cautioned.

To note, Biden's predecessor Trump has still not received the vaccine and won't be inoculated until recommended by the White House medical team, reports CNN.

Trump is "protected" by antibodies that he received after testing positive for coronavirus just days before the November elections.

However, Vice-President Mike Pence, his wife Karen Pence, and Surgeon General Jerome Adams have received the vaccine.
