AstraZeneca used ‘outdated and potentially misleading data’ that overstated the effectiveness of its vaccine, independent panel says
AstraZeneca said it would “immediately engage” with an independent data and safety monitoring board to discuss the most up-to-date efficacy data on its coronavirus vaccine.
In an extraordinary turn of events, an independent panel that safeguards the integrity of clinical trials wrote to AstraZeneca and U.S. government officials late Monday expressing concern and disappointment that the drugmaker presented “outdated and potentially misleading” data on its coronavirus vaccine making the shots appear more effective than shown by fuller data.
The letter, from 11 leading statisticians, infectious-disease physicians and ethics experts appointed by the National Institutes of Health to review the trial data for all the major coronavirus vaccines supported by the federal government, says the company’s decision puts the vaccine in the most favorable light — a grave scientific misstep that could erode trust in the vaccine...
...“The DSMB is concerned that AstraZeneca chose to use data that was already outdated and potentially misleading in their press release,” the letter states. “The point that is clear to the board is that the [vaccine efficacy number] . . . they chose to release was the most favorable for the study as opposed to the most recent and most complete. Decisions like this are what erode public trust in the scientific process.”
The letter goes on to explain that while the company announced its vaccine was 79 percent effective on Monday, the panel had been meeting with the company through February and March and had seen data showing the vaccine may be 69 to 74 percent effective, and had “strongly recommended” that information should be included in the news release.
Federal officials were taken aback by the letter from the board. One said the AstraZeneca results were the equivalent of “telling your mother you got an A in a course, when you got an A in the first quiz but a C in the overall course.” Another said the disclosure by the board would inevitably hurt the company’s credibility with U.S. regulators.
