More than 20 million adults in the UK are now fully vaccinated against COVID-19 after receiving both jabs, according to government figures.
Some 391,246 people were given their second dose on Saturday, meaning a total of 20,103,658 (38.2% of all adults) have now had two shots.
Also on Saturday, 237,331 had their first jab, bringing the total number of people who have been given at least one dose to 36,573,354 (69.4% of the adult population).
The government has said it remains on track to offer a first dose to all adults in the UK by the end of July.
Health Secretary Matt Hancock said: “We have more great news about the vaccination rollout and are making extraordinary strides as 20 million people now have the fullest possible protection from this virus – huge thanks to the team for hitting this milestone.
“The latest real-world data has once again demonstrated how effective the vaccine is at providing life-saving protection, with two doses of the Pfizer vaccine providing 97% protection against mortality.”
