It additionally pointed to its earlier findings that two doses of a Covid vaccine offers a “excessive diploma of safety” towards hospitalisation from the Delta variant.
“PHE’s weekly Covid-19 variant cases information present that numbers of the Delta variant in the UK have risen by 33,630 since final week to a whole of 75,953,” PHE reviews.
“The most up-to-date information present 99 per cent of sequenced and genotyped cases throughout the nation are the Delta variant.
