Health Secretary Matt Hancock said the government was "absolutely open" to delaying the end of lockdown, and that June 21 was a "not before" date that would depend on the data. He said the Delta coronavirus variant was about 40 times more transmissible than the Alpha strain, but added that hospitalisations were "broadly flat" which means the vaccine is working. Research has shown that while a single dose of the vaccine does offer some protection against severe illness, having had both doses offers is far safer. Mr Hancock urged people to get their second jab, saying: "The best scientific advice I have at this stage, is that after one jab it's not quite as effective against the new Delta variant, but after both jabs it is." Dr Julian Tang, a consultant virologist at the University of Leicester, said he thinks the end of lockdown should be delayed until at least 70 percent of the population is fully vaccinated.

"If you open everything up, you'll see a bigger surge, then the government will panic and shut everything down again. "From a purely virological point of view, you want to know what we're doing now is going to control the virus down the line. "At some point, you'll have to open up but that should happen when at least 70 percent of the population have had two doses. Trending  Dr Tang said that it is an inevitability that the virus will still remain in the population regardless of vaccinations. He said: "The government will have to decide what level of virus we can live with. "Immunologists who dream of eradicating this virus are just dreaming - respiratory viruses are seasonal and none have been eradicated." A final decision on whether to ease England's lockdown further will be made on 14 June.

Asked whether lockdown easing could be delayed if the data on the Delta variant appeared "bad," Mr Hancock said the government was "absolutely open to doing that if that's what needs to happen". He said the "roadmap was set up to take these changes into account". Mr Hancock added that while new infections have "risen a little", the number of people admitted to hospital with the Delta variant was "broadly flat".
