The US Food and Drug Administration has started investigating around five allergic reactions reported after administering Covid 19 vaccines Pfizer Inc and BioNTech SE`s COVID-19 vaccine to the people in the United States this week, a top FDA official said late on Friday. Dr. Peter Marks, director of the FDA`s Center for Biologics Evaluation and Research, said at a press conference that the allergic reactions had been reported in more than one state, including Alaska.
He also revealed that a chemical called polyethylene glycol (PEG) an ingredient in the Pfizer vaccine and also the Moderna Inc vaccine authorized on Friday "could be the culprit" causing the allergic reactions.The director said that allergic reactions to PEG could be somewhat more common than previously understood. The cases in Alaska are similar to the cases reported in Britain last week. Post report, Britain`s medical regulator has said that anyone with a history of anaphylaxis, or severe allergic reactions to a medicine or food, should not be given the Pfizer-BioNTech COVID-19 vaccine.
On contrary, US FDA has said that most Americans with allergies should be safe to receive the vaccine. It said only people who have previously had severe allergic reactions to vaccines or ingredients in this particular vaccine should avoid getting the shot. It also instructed people with a known history of a severe allergic reactions to any components of the shot should not be administered the Moderna. An appropriate medical treatments for immediate allergic reactions must be available when the shot is administered in case of an anaphylactic reaction, feels the FDA.
