Pfizer says an early peek at its vaccine data suggests the shots may be 90% effective at preventing COVID-19, indicating 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.A vaccine jointly developed by Pfizer and BioNTech was 90 percent effective in preventing Covid-19 infections in ongoing Phase 3 trials, the companies announced Monday.The statement was released as coronavirus cases are soaring across the world, and European stock markets and oil prices jumped on the news.

According to preliminary findings, protection in patients was achieved seven days after the second of two doses, and 28 days after the first.”The first set of results from our Phase 3 Covid-19 vaccine trial provides the initial evidence of our vaccine’s ability to prevent Covid-19,” Pfizer chairman and CEO Albert Bourla said in a statement.”We are a significant step closer to providing people around the world with a much-needed breakthrough to help bring an end to this global health crisis,” he said.
