In a modified intention-to-treat population, estimated vaccine efficacy (VE) was 88.0% (95% CI 70.0-95.8) against symptomatic COVID (primarily the Delta variant) at 14 days or more following the first injection, the authors wrote in the New England Journal of Medicine.

The manufacturer first shared top-line data from this trial in October 2021, although no efficacy results were reported at that time. More recently, Moderna announced it would be filing for emergency use authorization (EUA) for this vaccine and its vaccine for children 6 months to 5 years of age (two 25 μg doses). Read more …
