Moderna's stock falls following report that the Phase 3 coronavirus vaccine trial has been delayed
Shares of Moderna Inc. declined 6.2% in trading on Thursday after people familiar with the matter told Stat News the start date for the company's Phase 3 clinical trial for its experimental COVID-19 vaccine has been delayed. The sources attributed the delay to protocol changes - a common issue with clinical studies - not a problem with the vaccine candidate. Following publication of the story, Moderna tweeted that the Phase 3 trial is still set to begin in July. "We have worked closely with [the National Institutes of Health/Operation Warp Speed] to align on the final protocol in order to begin the trial on time," it said. Moderna's stock has soared 197.7% year-to-date, while the S&P 500 is down 3.5%.
