NEW YORK – The U.S. Food and Drug Administration is investigating about five allergic reactions that occurred after people received the Pfizer Inc vaccine and the BioIDech SE CONTID-19 vaccine in the United States this week, he said. FDA chief executive late Friday.

Dr. Peter Marks, director of the FDA’s Center for Biological Assessment and Research, said at a press conference that the allergic reactions have been reported in more than one state, including in Alaska.

Marks also said a chemical called polyethylene glycol (PEG) contained in the Pfizer vaccine – as well as the Moderna Inc vaccine authorized on Friday – could “cause a culture” causing the reactions.

Marks said an allergic reaction to PEG may be slightly more common than previously understood.
