British Prime Minister Boris Johnson said Monday that it's looking good for July 19 to be a "terminus point" for COVID-19 restrictions in England, but warned of rise in Delta variant cases.

"We've got to be cautious but we'll be following the data the whole time. But looking at where we are, the efficacy of the vaccine against all variants that we can currently see... I think it is looking good for July 19 to be that terminus point," Johnson said during a visit to a laboratory in Hertfordshire, southern England.
