Moderna to Ask Health Regulators to Authorize Its Covid-19 Vaccine

Moderna said it would ask U.S. and European health regulators Monday to authorize use of its Covid-19 vaccine, after it was shown to be 94.1% effective in a full analysis of a pivotal study. The timing keeps the vaccine on track to become possibly the second to go into use in the U.S. by year’s end—after one already under regulatory review from Pfizer Inc. and BioNTech SE —with inoculation available to the general public likely in spring or summer. Moderna said some doses also could become available in Europe in December. In the 30,000-person trial, 196 subjects developed Covid-19 with symptoms after receiving either the vaccine or a placebo, Moderna said. Of those, 185 had taken a placebo, while only 11 had gotten the vaccine, indicating it protects against the disease.
