Every adult in the UK will be asked to take a coronavirus test twice a week, it has been reported.
The Times said on Monday that people will be encouraged to take two weekly COVID-19 tests to help ease out of lockdown.
It said an advertising campaign will be launched to ask the public to “play their part” with regular tests.
Officials hope the combination of the vaccine rollout and regular testing will bring down coronavirus case levels.
Boris Johnson hailed the news as “a record-breaking day for the vaccine rollout”.
NHS chief executive Sir Simon Stevens said: “In just one day we vaccinated the equivalent of the entire adult populations of Liverpool, Southampton and Oxford combined.”
More than 27.6 million people, more than half the UK adult population, have had at least one dose of a coronavirus vaccine.
Johnson, who received his first dose on Friday, said: "A huge thank you to everyone involved and please come forward to get your jab when you are invited to do so."
