Professor Tim Spector, who runs the study, said: “Covid cases continue to soar to all-time highs but the rate of increase is showing signs of slowing down.
“This is a promising sign that we’ll hopefully see case numbers beginning to drop once again.â€
Government advisers still struck cautious tones with Prof Chris Whitty warning there is high pressure on the NHS.
Dr Jenny Harries, chief of the UK Health Security Agency, said Brits have to “come to terms†with the fact Covid will spread for years.

Health Secretary Sajid Javid said scrapping large-scale testing and reserving it for high-risk cases is now the right move.
He said: “We are one of the most open and free countries in the world now and it is right also as we learn to live with Covid that we withdraw free testing if it’s not needed any more.â€
