The U.S. FDA states that appropriate medical treatments for immediate sensory reaction must be available when the picture is administered in case of anaphylactic reaction.
The U.S. Food and Drug Administration is investigating about five allergic reactions that occurred after people received the Pfizer-BioNTech’s Covid-19 vaccine in the United States this week.
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.

The situation in Alaska was similar to two cases reported last week in Britain.
The British medical regulator has said that the Pfizer-BioNTech Covid-19 vaccine should not be given to anyone with a history of anaphylaxis, or a severe allergic reaction to a drug or food.
But the U.S. Food and Drug Administration has said most Americans with allergies should be safe to be vaccinated. He said only people who have had a severe allergic reaction to vaccines or ingredients in this particular vaccine should avoid getting the picture.
On Friday, the FDA said the Moderna vaccine should not be given to individuals with a known history of severe allergic reactions to any parts of the picture.
The regulator also demands that appropriate medical treatments for immediate sensory response must be available when the picture is given in case of anaphylactic reaction.
Pfizer could not be immediately reached for reference.
