Half of adults in England are likely to have received their first dose of Covid-19 vaccine, new figures suggest.
A total of 22,337,590 people had been given a first jab as of March 18th, according to NHS England.
This is the equivalent of 50.5 per cent of the population of England aged 18 and over, based on the latest estimates by the Office for National Statistics.
England is the first of the four nations within the United Kingdom to pass the symbolic milestone.
Wales is currently at the equivalent of 47.7 per cent of adults, Scotland 46.6 per cent and Northern Ireland 45.1 per cent.
A separate milestone has been passed in Wales, where one in 10 of the total population is likely to have had both doses of the vaccine.
Latest figures show that 318,976 people in Wales have received two doses, the equivalent of 10.1 per cent of the population.
Wales is well ahead of the other three nations in terms of second doses.
England has fully vaccinated 2.5 per cent of its total population, while for both Scotland and Northern Ireland the figure is 3.7 per cent.
Among adults only, Wales has given both doses to the equivalent of 12.6 per cent of people 18 and over, Northern Ireland 4.9 per cent, Scotland 4.5 per cent and England 3.2 per cent.
All vaccine figures have been published by the health agencies in the four UK nations.
