Pfizer says an early peek at its vaccine data suggests the shots may be 90 percent effective at preventing coronavirus disease 2019 (Covid-19), indicating the company is on track later this month to file an emergency use application with United States regulators. Pfizer Inc. did not provide any more details about those cases, and cautioned the initial protection rate might change by the time the study ends. Volunteers in the final-stage studies, and the researchers, don’t know who received the real vaccine or a dummy shot. The agency has made clear that any vaccine must be at least 50 percent effective. Pfizer expects to reach that milestone later this month, but said Monday no serious safety concerns have been reported.
