Over 20 million people in the UK have now received their first dose of the coronavirus vaccine, the government has said.
Prime Minister Boris Johnson hailed the milestone as "a huge national achievement" and a "testament to the tireless work of NHS staff, volunteers, the Armed Forces and many more."
Mr Johnson tweeted on Sunday: "20 million people across the UK have now got the jab – a huge national achievement and a testament to the tireless work of NHS staff, volunteers, the Armed Forces and many more.
"I urge everyone to get the jab when called. Every jab makes a difference in our battle against Covid."
In a video shared on Twitter on Sunday, Health Secretary Matt Hancock described the news as a "magnificent achievement for the country."
He said: "I'm absolutely delighted that over 20 million people have now been vaccinated across the UK – it's absolutely fantastic.
"I want to thank every single person who's come forward to get the jab because we know with increasing confidence that the jab protects you, it protects your community and it also is the route out of this for all of us."

The news comes after the government set out who will be next in line to receive the coronavirus vaccines once all the over-50s and most vulnerable have had their jabs.
The Joint Committee on Vaccination and Immunisation has recommended prioritisation should continue down the age ranges, with people in their 40s invited next for the vaccine.

NHS chief executive Sir Simon Stevens said: “Vaccinating 20 million people – including 17 million across England – in a few short weeks shows the NHS vaccination campaign is firing on all cylinders, and looking out to Easter and beyond it's full speed ahead.
"As we can see from other parts of the world, having vaccines from the manufacturers versus actually administering them to patients can be two different things.
"So this latest milestone is also a tribute to careful health service planning, effective organisation and amazing teamwork across the whole of the country."
