A further 1,820 people have died within 28 days of testing positive for COVID-19 – the highest number of UK deaths reported on a single day since the outbreak began.
It surpasses the previous record number announced yesterday of 1,610.
The government has also said there were also another 38,905 coronavirus cases recorded in the past 24 hours, compared to 33,355 a day earlier.
New figures from the vaccine programme show another 343,163 people have been given a first jab, taking the total to 4,609,740 up to 19 January.
Ahead of the latest data being published, the UK was facing questions as to its vaccination strategy after a study of Israeli jab data suggested that the efficacy of one dose of the Pfizer/BioNTech vaccine is just 33%.
The government has previously said that efficacy was “around 90%”, starting 14 days after the first dose.
In response, Sir Patrick Vallance, the government’s chief scientific adviser, told Sky News the UK will need to “keep measuring the numbers” as the vaccine is rolled out across the UK.
While the UK compares favourably to other countries when it comes to vaccination, two doses are needed for the most comprehensive protection. To date, just over 456,000 people have had a second jab.
