AstraZeneca said on Tuesday morning that its results were based on an interim analysis of data before Feb. 17, more than a month ago.
Federal health officials are casting doubts about AstraZeneca’s vaccine data just hours after the company announced that its shot is safe and effective, leading the drugmaker to promise updated data within two days.
The National Institute of Allergy and Infectious Diseases said in a rare statement late Monday that its Data and Safety Monitoring Board, the independent panel overseeing coronavirus vaccine trials, that it was concerned AstraZeneca had included “outdated information” in an announcement touting its shot’s 79 percent effectiveness against the virus.
The DSMB “wrote a rather harsh note” to AstraZeneca with NIAID Director — and Biden medical adviser — Anthony Fauci copied in, he told POLITICO. “The issue that the DSMB had is straightforward and very simple: The DSMB had data that they know the company had. When they saw the press release, they said, ‘wait a minute — the data in the press release do not reflect the most recent data that we know you have,'” he said.
