"We have to ask very hard questions," a virus expert says, about what restrictions and the test and trace programme are achieving in a largely vaccinated population.
Prof Robert Dingwall, who sits on the government's New and Emerging Respiratory Virus Threats Advisory Group (NERVTAG), tells BBC Radio 4's The World At One programme there were "significant commercial interests" in prolonging things like test and trace but from a public policy point of view there were questions to be asked.
"We have never thought it was important to do differential diagnosis of school children with respiratory infections," he says. "If they're not well enough to go to school, they don't go to school, that's the sort of equilibrium we need to be moving towards when the school year restarts in the autumn."
On whether we should still be using the test and trace app he says: "It's very hard to see what the benefit of that is, if the most vulnerable people in the population have had the opportunity to be vaccinated and if those who are not vaccinated are confined predominantly to groups where the infection is a very low risk, what are we achieving by contact tracing, by isolation?
"Why is it relevant to me to know that someone in my network is infected when I have been vaccinated?"
