AstraZeneca will likely release a modified statement regarding its Covid-19 vaccine after the accuracy of the company’s clinical trials results were thrown into question earlier this week, White House chief medical advisor Dr. Anthony Fauci said Wednesday.
The company on Monday announced the long-awaited results of its phase three clinical trial of the Covid-19 vaccine it developed with the University of Oxford, saying it was 79% effective in preventing symptomatic illness and 100% effective against severe disease and hospitalization.
The next day, the National Institute of Allergy and Infectious Diseases released an unusual statement that said it was informed by the data and safety monitoring board overseeing the trial that the U.K.-based company may have included information in its U.S. results that provided an “incomplete view of the efficacy data.”
Fauci, the director of the NIAID, said the DSMB raised concerns with the U.S. agency because it felt the results in AstraZeneca’s press release looked more favorable than more recent data from the vaccine study had shown, according to STAT News.
The company is now working with the DSMB and “will likely come out with a modified statement,” Fauci told reporters Wednesday during a White House news briefing on the pandemic.
