In its news analysis, PHE claimed that  protection against death from the Pfizer-BioNTech vaccine rises from approximately 80 per cent after one dose to 97 per cent after two doses. 


The study observed that people who had a single dose of AstraZeneca vaccine were 55 per cent protected against death, with a figure of 44 per cent protection for a single dose of Pfizer, compared to unvaccinated people. It looked at new symptomatic cases of Covid-19 between December and April and people who died within 28 days of their positive test by vaccination status.


PHE further said, "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."
