Watch: UK death toll rises by four
On Saturday, government data showed that Covid cases were up 70 per cent in a week.
Data also showed a total of 57,193,641 Covid-19 vaccinations took place in England between December 8 and June 5, including first and second doses, which is a rise of 590,645 on the previous day.
NHS England said 33,700,486 were the first dose of a vaccine, a rise of 175,001 on the previous day, while 23,493,155 were a second dose, an increase of 415,644.
It comes as a surge in Covid-19 cases including the Indian variant continues to spread across the UK.
Health secretary Matt Hancock said the spread of the Indian variant has made the decisions behind the June 21 unlocking “more difficult” as he confirmed that it is 40 per cent more transmissible than the Kent variant.
Speaking to Sky News, Mr Hancock said: “That means that it is more difficult to manage this virus with the new Delta variant.
“But crucially, after two doses of vaccine, we are confident that you get the same protection that you did with the old variant.
“So the good news is that the vaccine still works just as effectively.
“Everybody must go and get their second jab though because the first isn’t as effective on its own.
“So ultimately it does make the calculation more difficult for June 21 but it doesn’t change our strategy which is we all need to go and get vaccinated and that way we will break this link between the number of cases to the number of hospitalisations.”
“This week we will be opening up vaccines to the under-30s and so we are getting a step closer to the point when we have been able to offer the vaccine to all adults in this country,” he said.
“Then, once we have got everybody having had their second dose, then you will get this protection that we are seeing at the moment among older people, you’ll get that protection throughout the whole adult population.”
