A real-world test of Israel’s mass vaccination program shows that the Pfizer-BioNTech COVID-19 vaccine is highly effective at preventing death, severe illness and hospitalisations.
The 94% efficacy rate from the two-dose regimen, based on data from more than half a million vaccinated individuals in a case-control study, is consistent with findings from Pfizer’s phase III randomised controlled trial.
