The UK has seen the third consecutive day with a record number of COVID vaccinations, after 873,784 people received a jab over 24 hours.
NHS England revealed during one hour on Saturday, jabs were given out at a rate of 26 a second.
Prime Minister Boris Johnson announced the figure, tweeting: "A huge thank you to everyone involved and please come forward to get your jab when you are invited to do so."
The figure equates to roughly 1.3% of the UK population receiving a vaccination in the last 24 hours – and means more than 2.24 million people have received a jab in the last three days.
Defence secretary Ben Wallace warned "we can’t be deaf and blind to what’s going on outside the UK".
Speaking to Sophy Ridge on Sunday, he added: "We can’t put at risk the gains of our vaccination campaign."
It comes as Boris Johnson is facing a Tory revolt over a move to extend emergency coronavirus laws, with one leading lockdown critic vowing to oppose the "excessive and disproportionate" powers.
Conservative former minister Steve Baker told Sophy Ridge he expected to vote "squarely against" the continuation of the "authoritarian" COVID-19 restrictions.
MPs are due to vote this week on keeping the coronavirus laws in place for another six months until October.
