Two doses of either the Pfizer/BioNTech or Oxford/AstraZeneca vaccine offer similar protection against coronavirus as natural immunity after infection, new research suggests.
None of the 1,456 healthcare workers at Oxford University Hospitals (OUH) NHS Foundation Trust in Britain who had received two vaccines had a symptomatic infection when followed up more than 14 days after their second vaccination.
