LONDON — A U.S. health agency on Tuesday expressed concern that AstraZeneca might have included outdated info from a scientific trial of its Covid-19 vaccine, doubtlessly casting doubt over revealed efficacy outcomes.

The Data Safety Monitoring Board “expressed concern that AstraZeneca may have included outdated information from that trial, which may have provided an incomplete view of the efficacy data,” the U.S. National Institute of Allergy and Infectious Diseases stated in an announcement.

“We urge the company to work with the DSMB to review the efficacy data and ensure the most accurate, up-to-date efficacy data be made public as quickly as possible.”

The NIAID is led by White House Chief Medical Advisor Dr. Anthony Fauci and is a part of the National Institutes of Health.

AstraZeneca didn’t instantly reply to a CNBC request for remark.

The assertion comes simply someday after the findings of a big U.S. trial confirmed that the coronavirus vaccine developed by AstraZeneca and the University of Oxford is 79% efficient in stopping symptomatic sickness and 100% efficient in opposition to extreme illness and hospitalization.

Data from the late-stage human trial examine was based mostly on greater than 32,000 volunteers throughout 88 trial facilities within the U.S., Peru and Chile.

The findings had been welcomed as “surprisingly constructive” and “good news for the global community.”

AstraZeneca stated it deliberate to arrange for the first evaluation to be submitted to the U.S. Food and Drug Administration for emergency use authorization earlier than mid-April.

The Oxford-AstraZeneca vaccine had been briefly suspended in a number of international locations after reviews of blood clots in some vaccinated individuals. However, AstraZeneca stated Monday that the unbiased DSMB had discovered no elevated threat of blood clots.

Ruud Dobber, government vice chairman of AstraZeneca’s biopharmaceuticals enterprise unit, informed CNBC’s “Squawk Box” on Monday that it was “very pleasing to see that even with a magnifying glass the Data Saftey Monitoring Board didn’t see any imbalance between the vaccinated group and the placebo group.”

“So, that gives us a lot of confidence,” he added.
