Investing.com -- Shares of major Covid-19 vaccine manufacturers Moderna (NASDAQ:MRNA), Pfizer (NYSE:PFE), and BioNTech (NASDAQ:BNTX) briefly tumbled Tuesday following a Bloomberg report that the Food and Drug Administration is investigating potential adult deaths linked to Covid-19 vaccines.
The FDA probe is more extensive than previously understood, as it encompasses both adult and pediatric cases. "FDA is doing a thorough investigation, across multiple age groups, of deaths potentially related to Covid vaccines," an agency spokesperson told Bloomberg on Tuesday.
The investigation spans multiple divisions within the FDA. Earlier reports had suggested the review was limited to pediatric cases. The news comes after Vinay Prasad, the FDA’s top vaccine regulator, claimed in a leaked internal memo last month that a review had found 10 children died because they received a Covid vaccine.
