New Public Health England analysis continues to show vaccination is highly effective in protecting against death and hospitalisation from COVID-19

Analysis shows single dose of AstraZeneca vaccine has ~ 80% lower risk of death with COVID-19 compared with unvaccinated individuals and protection against death from Pfizer-BioNTech vaccine rises from ~80% after 1 dose to 97% after 2 doses.

SPS commentary:

A separate analysis confirms that the Pfizer-BioNTech vaccine is highly effective in reducing risk of hospitalisation, especially in older ages. The vast majority of confirmed COVID-19 case data analysed in these reports are expected to be the B.1.1.7 (Kent) variant.
