The Pfizer/BioNTech vaccine against Covid-19 performs even better than previously thought, with 95% efficacy, equalling the early results from Moderna on Monday, according to an analysis of the final data from their trials, which paves the way for regulators to grant an emergency licence and vaccination campaigns to begin.
The news will excite scientists, public health experts and politicians. Pfizer/BioNTech say they also have the necessary safety data that regulatory bodies require, and will submit the vaccine for emergency approval within days to the US Food and Drug Administration and other regulators around the world.
