AstraZeneca announced that its coronavirus vaccine candidate is up to 90% effective based on interim results from late-stage clinical trials. Vaccine efficacy in the trial ranged from 62% to 90% (depending on the dosing regimen), and the company reported no serious safety events during the trials. The news follows announcements from Pfizer and Moderna last week, both of which found their vaccines to be ~95% effective in late-stage trials.
