Two doses of Covid-19 vaccine was found to be highly effective against the Delta variant, although not preventing the disease altogether but the decreasing need for hospitalisation due to the Delta variant.

All symptomatic Covid-19 cases that occurred between April 12 and June 4 were linked to the Emergency Care Dataset (ECDS) that records all hospital admissions through emergency departments of England. The 509 genome sequences revealed 13 cases of the Delta variant, eight of the Alpha variant, and 112 of the Beta variant, among other variants of concern.

The variant has also threatened to delay reopening plans in the country and much of the world.
