More than 30 million people in the UK have now had a first COVID vaccine dose.
New government figures show 30,151,287 have had a first dose - around 57% of all UK adults.
A total of 3,527,481 have now had two vaccine doses - 6% of the adult population.
Ministers remain confident that all over-50s will have been offered the first dose by 15 April. The government aims to offer all adults a jab by the end of July.
Health Secretary Matt Hancock said: "I'm absolutely thrilled that more than 30 million people have now had the jab across the UK - including 650,000 vaccinations delivered yesterday.
"The vaccine is saving lives and is our route out of this pandemic. I want to say a massive thanks to the team.
"When you get the call - get the jab."
The UK is expecting its first batch of Moderna jabs next month, a development which could see the vaccine rollout expanded to those aged between 40 and 49.
"We examined the data from Moderna, which looks very promising," Professor Anthony Harnden, deputy chair of the Joint Committee on Vaccination and Immunisation (JCVI), told BBC Breakfast on Sunday.
"If we've caught up with all those over-50s we want to reach out to, it makes sense to go toward our next age group, which is the 40 to 49-year-old age group."
In all, the UK has ordered 17 million doses of the Moderna jab, 100 million doses of Oxford-AstraZeneca, and 40 million doses of BioNTech/Pfizer.
It has also ordered millions of doses of vaccines not yet approved by the Medicines and Healthcare Products Regulatory Authority:
- GlaxoSmithKline/Sanofi Pasteur (60 million doses)
- Novavax (60 million doses)
- Janssen (30 million doses)
- Valneva (100 million doses)
- CureVac (50 million doses)
