More than 20 million people in the UK have received at least a first dose of coronavirus vaccine, with under 4% of those given as second doses.
Government data shows that of the 20.5m jabs given in the UK up to 26 February, 19.6m were first doses.
About 770,000 of the doses given were second jabs, an increase of nearly 33,000 on figures released the previous day.
This means just over 1.1% of the UK population have been fully vaccinated with two doses.
A total of 17.25m Covid-19 vaccinations took place in England between 8 December and 26 February, according to provisional NHS England data, a rise of just under 470,000 on the previous day’s running total.
The same data shows a total of just over 2m jabs were given to London’s population of about 9 million between 8 December and 26 February, including 1.98m first doses.
Over 1m doses have been administered across Wales in the 12 weeks since the rollout of the country’s vaccination programme began, and more than one in three of the country’s adult population have received at least one dose, data published by Public Health Wales shows.
In Scotland, by Saturday, 1.57 million people had received the first dose of the Covid vaccine and 72,178 have received their second dose.
More than half a million people in Northern Ireland have received a first jab, and nearly 32,000 have also received a second dose.
Meanwhile, the government said a further 290 people had died within 28 days of testing positive for Covid-19 as of Saturday, bringing the UK total to 122,705.
Seven days prior, on 20 February, 445 further fatalities from the virus had been recorded.

On Saturday a further 7,434 lab-confirmed cases were recorded in the UK, the lowest daily rise in cases since 2 October, a sharp drop from the 10,406 cases on the same day a week ago.
