One AZ COVID-19 vaccine dose gives 80% lower death risk – English data

Public Health England announced on Monday that data from the rollout of AstraZeneca’s coronavirus vaccine shows one dose of the shot gives 80% less risk of death from the disease.

It added that protection against death from the Pfizer-BioNTech vaccine jumps from roughly 80% after 1 dose to 97% after 2 doses in its new analysis.

PHE noted that the study was the first on protection against mortality from the AstraZeneca vaccine according to data from a real world setting.

The study looked at new symptomatic cases of coronavirus between December and April and people who passed away within 28 days of their positive test by vaccination status.

People who had a single dose of AstraZeneca vaccine were 55% protected against death, with a figure of 44% protection for a single dose of Pfizer, compared to unvaccinated people.

“Combined with the protection vaccines offer against becoming a case in the first place, this is equivalent to approximately 80% protection against mortality in individuals vaccinated with a single dose of either vaccine,” PHE said in a statement.
