AstraZeneca Covid shot 94 percent protective against death in people over 65: Public Health England

PHE also said that for the under 40s, early estimates suggested a single dose of Pfizer's vaccine is 61% effective against symptomatic disease and a single dose of the Moderna vaccine is 72% effective.

Two doses of the Oxford/AstraZeneca Covid-19 vaccine gives an estimated 94 percent protection against death from the disease in people over 65, Public Health England said on Thursday in a weekly surveillance report of real-world data.
