One in five UK adults are now fully vaccinated against Covid-19, with more than two-and-a-half million second doses delivered in the past seven days, latest figures show.
A total of 10.8 million people have now received both jabs – the equivalent of 20.5% of the adult population.
Wales is estimated to have given two doses to just under a quarter of adults (24.7%), ahead of Northern Ireland (20.5%), England (20.3%) and Scotland (19.1%).
The figures are for vaccinations reported by the UK’s health agencies up to and including April 20, and reflect the pace at which second doses have been ramped up across the country during the past month.
Some 2.6 million second doses were recorded in the seven days to April 20, with 6.3 million since April 1.
This compares with 3.7 million second doses in March and just 322,000 in February.
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 published last week by NHS England suggested around three-quarters of people in England in this age group have now had both doses of vaccine.
In Wales, 78% of people aged 80 and over are estimated to have had both jabs, along with 80% in Scotland and 42% in Northern Ireland.
Wales leads the field in both first and second doses of vaccine, with more than two-thirds of its adult population having received the first jab (67.9%), followed by England (62.8%), Scotland (62.1%) and Northern Ireland (60.3%).
