The U.S. FDA released their data study of Moderna’s mRNA vaccine today, showing both safety and efficacy. It is now to be reviewed by the FDA’s independent advisory committee on Dec. 17, and could be approved for an Emergency Use Authorization by Dec. 18 or Dec. 21. About a quarter of the participants were healthcare workers, and the ones who received placebos will be first in line to be given an opportunity to get the vaccine. Moderna’s study of over 30,000 participants did not include sufficient numbers of teenagers, pregnant women and nursing women — so those groups will not be allowed to take the vaccine at this point.
