The first Covid-19 vaccination in the United States has taken place, as the country gears up for its largest ever immunisation campaign.
"I feel like healing is coming," said New York nurse Sandra Lindsay - among the first health workers given the jab.
On Monday, as the US death toll topped 300,000, 150 hospitals across the country were to receive millions of vials of the Pfizer/BioNTech vaccine.
The US vaccination programme aims to reach 100 million people by April.
Ms Lindsay, an intensive care nurse at Long Island Jewish Medical Center, received the vaccine live on camera. Footage was streamed on the Twitter feed of New York Governor Andrew Cuomo, whose state was the epicentre of the US epidemic in the first wave earlier this year.
"It didn't feel any different from taking any other vaccine," Ms Lindsay said. "I hope this marks the beginning of the end of a very painful time in our history. I want to instil public confidence that the vaccine is safe. We're in a pandemic and so we all need to do our part."
"First Vaccine Administered. Congratulations USA! Congratulations WORLD!" President Donald Trump tweeted on Monday morning following the news from New York.
