UPDATED: Moderna calibrates final Covid-19 vaccine efficacy at 94.1% and today it’s gunning for the EUA – Endpoints News

Pascal Soriot spent the long Thanksgiving weekend digging AstraZeneca out of a hole, promising to put an end to the questions around its interim Phase III vaccine data by conducting a new study while going to regulators with a large part of what it already has.

AstraZeneca and its partners at Oxford had initially touted high-level results from two studies conducted in the UK and Brazil as positive. But the enthusiasm was soon shadowed by confusion as observers probed into how the highest, 90% efficacy was seen in a dosing regimen given to a small group of volunteers due to an error. Among a larger cohort given the intended shots, the vaccine was only 62% effective, a rate that wouldve been respectable had Pfizer/BioNTech and Moderna not posted efficacy rates of 94%, 95% for their mRNA candidates. And many werent sure what to make of the average 70% number that AstraZeneca ran in headlines.
