Pfizer says early data on its coronavirus vaccine candidate suggest the shots may be 90% effective at preventing COVID-19

“We’re in a position potentially to be able to offer some hope,” Dr. Bill Gruber, Pfizer’s senior vice president of clinical development, told the Associated Press. “We’re very encouraged.”

Pfizer says early data on its coronavirus vaccine candidate suggest the shots may be 90% effective at preventing COVID-19, indicating that the company is on track later this month to file an emergency-use application with U.S. regulators.

Monday’s announcement doesn’t mean a vaccine is imminent. This interim analysis, from an independent data monitoring board, looked at 94 infections recorded so far in a study that has enrolled nearly 44,000 people in the U.S. and five other countries.

Pfizer did not provide any more details about those cases, and cautioned that the initial protection rate might change by the time the study ends. Even revealing such early data is highly unusual.
