Three in four people in England aged 60 and over are fully vaccinated against Covid-19, figures suggest.
An estimated 75.2% of people in this age group had received both doses of the vaccine as of May 9.
For people aged 55 to 59 the figure is 28.6%, while for 50 to 54-year-olds the estimate is 23.0%.
People aged 60 and over were in the top seven groups on the priority list for vaccines, with initial doses offered to over-80s from early December and over-70s from mid-January.
The figures for vaccinations were published by NHS England, and have been combined with population estimates from the Office for National Statistics.
They suggest 18.2% of 45 to 49-year-olds have had both doses, along with 16.4% of 40 to 44-year-olds.
Some 9.8% of people aged 16 to 39 are also likely to have received both jabs.
Analysis by the PA news agency shows that at local authority level, the highest estimated proportion of people aged 60 and over to be fully vaccinated is in Surrey Heath (87.1%), Mid Suffolk (86.7%) and Wyre Forest (84.8%).
The lowest proportion is in the London borough of Tower Hamlets (50.5%), the City of London (51.3%), and the London borough of Newham (51.8%).
Meanwhile more than two-thirds of people in England aged 40 to 44 are likely to have had their first dose of Covid-19 vaccine.
An estimated 67.6% of people in this age group had received their first jab as of May 9, NHS England said.
The figures also suggest 77.9% of people aged 45 to 49 have had their first dose, along with 89.8% of 50 to 54-year-olds and 95.5% of 55 to 59-year-olds.
Some 97.2% of people aged 60 and over have had a first dose.
