More than one million people in the UK have now received both doses of Covid-19 vaccine.
A total of 1,034,068 second doses had been given by March 4, according to the latest figures from health agencies in the four nations.
It means the equivalent of 2% of UK adults are now fully vaccinated against coronavirus.
The cumulative number of second doses in the UK passed half a million on February 3, and started to pick up pace in the second half of last month, passing 800,000 on February 28 and 900,000 on March 3.
The seven-day rolling average of daily second doses stood at 4,253 on February 15, but had jumped to 27,356 by February 28.
Speaking earlier this week, vaccines minister Nadhim Zahawi said March would be a “very big month” for vaccinations.
“You have seen the numbers tick up of second doses – yesterday I think we were at 800,000 second doses,” he told the BBC on Monday.
“The NHS have got all the protocols in place to deliver that, as well as of course continuing to do the first dose.
“March will be a very big month for us. We’ll probably going to be twice the rate over the next 10 weeks as we have done over the past 10 or 11 weeks.”
