From BBC website:
The two Covid vaccines most in use in the UK are "highly effective" in preventing hospital admission with the Delta variant, new data from Public Health England suggests.
Both the Pfizer-BioNTech and Oxford-AstraZeneca jabs can cope with the variant first identified in India as the Alpha variant first identified in Kent, the research found.
The Pfizer-BioNTech vaccine was found to be 94% effective against hospital admission after just one dose, and 96% after two doses.
The Oxford-AstraZeneca vaccine was found to be 71% effective against hospital admission after one dose, and 92% after two doses.
PHE says the protection against death is expected to be high, although further research is taking place.
