People aged 70 or over who have not yet had a Covid jab are being urged to come forward, in a final push by ministers to meet their vaccination target.
More than 14 million people in the UK have had at least one dose – with the aim being 15 million by Monday.
Meanwhile, Health Secretary Matt Hancock has said the UK could this year live with Covid “like we do with flu”.
“I hope that Covid-19 will become a treatable disease by the end of the year,” he told the Daily Telegraph.
Over the weekend, ministers are taking part in a renewed drive to encourage people in the top four priority groups – comprising of people aged 70 and over, front-line health and social care workers, care home residents and the clinically extremely vulnerable – to get vaccinated.
Vaccinating the 15 million people in these priority groups would cover 88% of those most at risk of dying from Covid-19.
Overall uptake of the vaccine has been high, with a 93% take-up rate among the over-75s in England, according to the Department of Health and Social Care (DHSC).
Across the UK, a quarter of adults have already received one dose, including around nine in 10 over-70s.
