Covid vaccinations have "weakened" the link between infections and hospital admissions, but it is not "completely broken", an expert has said.
Sir Peter Horby, professor of emerging infectious diseases in the Nuffield Department of Medicine, University of Oxford, told the BBC's Andrew Marr Show: "They've certainly weakened the link, we're seeing quite a different situation now.
"We're definitely seeing increasing infection rates, but what we're seeing is a much lower level of hospitalisation.
"So that link is really, really much weaker, which is really fantastic. But it's not completely broken.
"As we see increasing infections, we will see increasing hospitalisations.
"But at this stage, we're able to make sure that the health system isn't overwhelmed and vaccination is really key to that."
A further 23 deaths were also been reported. Last Saturday there were 10,321 new infections and 14 deaths.
Sir Peter said despite the increase in infection "encouraging" Covid data suggested restrictions in England could be eased by July 19.
“We're watching it very carefully and there will be a lot of analysis of the data coming up to that date, to make sure we're comfortable with that release.
"At the moment, the data is encouraging that we can do that. But we have to make sure that we follow the data."
He said he would not bring the restrictions easing date forward, adding that it had been "very sensible" to delay the previous June 21 target date by four weeks.
"I don't think we should rush into anything, we really want to make sure that we can release all restrictions and not have to backtrack at all," he added.
