Analysis by Public Health England (PHE) has shown that two doses of COVID-19 vaccines are highly effective against hospitalization as a result of infection with the Delta variant of COVID-19.
The real-world data, which were announced in a June 14, 2021 press release, have shown that two doses of the Pfizer-BioNTech vaccine are 96% effective at preventing hospitalization and two doses of the Oxford-AstraZeneca vaccine are 92% effective against hospitalization due to the Delta variant of COVID-19. These results are comparable with the efficacy found against hospitalization from the Alpha variant of the virus.
