A Public Health England analysis of the COVID-19 vaccine has shown:

Two doses of the AstraZeneca vaccine was about 92 per cent effective against hospitalisation from the Delta variant.

Two doses of the Pfizer vaccine was about 96 per cent effective against hospitalisation from the Delta variant.

Single dose effectiveness is not so close, between the two.

One dose of the AstraZeneca vaccine was about 71 per cent effective against hospitalisation from the Delta variant.

One dose of the Pfizer vaccine was about 94 per cent effective against hospitalisation from the Delta variant.
