One in six UK adults are now fully vaccinated against Covid-19, with more than two million second doses delivered in the past seven days, latest figures show.
A total of 8.9 million people have now received both jabs – the equivalent of 17% of the adult population.
Wales is estimated to have given two doses to nearly a quarter of adults (22.8%), some way ahead of Northern Ireland (17.2%), England (16.8%) and Scotland (15.5%).
The figures are for vaccinations reported by the UK’s health agencies up to April 15, and reflect the pace at which second doses are being ramped up across the country.
Some 2.4 million second doses were recorded in the seven days to April 15, compared with 1.6 million, 1.9 million and just under one million in the previous three weeks.
Second doses of Covid-19 vaccines must follow within 12 weeks of the first, meaning the millions of people who received their initial jab in January and early February have recently had a follow-up dose, or are due to get the jab shortly.
People aged 80 and over were among the first groups on the priority list for vaccines, with initial doses offered from early December.
Figures released on Thursday by NHS England suggest around three-quarters of people in England in this age group have now had both doses of vaccine.
In Wales, 67% of people 80 and over are estimated to have had both jabs, along with 72% in Scotland and 41% in Northern Ireland.
Wales leads the field in both first and second doses of vaccine, with nearly two-thirds of its adult population having received the first jab (65.7%), followed by England (61.8%), Scotland (61.4%) and Northern Ireland (58.5%).
