Around two-thirds of people in England aged 70 and over are fully vaccinated against Covid-19, figures suggest.
An estimated 67.1% of people in this age group had received both doses of the vaccine as of April 18.
For people aged 80 and over the figure is 83.3%, while for 75 to 79-year-olds the estimate is 78.3%.
Some 42.7% of 70 to 74-year-olds are also likely to have had both doses.
Second doses must follow within 12 weeks of the first, meaning people in these age groups yet to have a follow-up jab should receive it within the next few weeks.
The figures for vaccinations were published by NHS England, and have been combined with population estimates from the Office for National Statistics.
Some 6.6% – or one in 15 – of people aged 16 to 44 are also likely to have received both jabs.
Meanwhile, an estimated 89.7% of people aged 45 and over in England have now received their first dose of vaccine, including 59.3% of 45 to 49-year-olds.
Analysis by the PA news agency shows that at local authority level, the highest estimated take-up of first doses for people 45 and over is in Warwick (96.8%), Stratford-on-Avon (96.1%) and Stroud (95.7%).
The lowest take-up is in the London boroughs of Westminster (63.4%), City of London (66.3%) and Camden (67.8%).
