Amid growing reports of severe allergic reactions to COVID-19 vaccines, regulators are warning people with a history of such reactions to take precautions before they get their shots.
Experts say the number one suspect for these reactions is an ingredient commonly found in cosmetics, other medicine and laxatives called polyethylene glycol, or PEG. The Centers for Disease Control and Prevention says the reactions are still rare and investigations are ongoing.
The ingredient in question is used to stabilize current COVID-19 vaccines. But PEG has caused anaphylaxis, severe allergic reactions, in the past, said Ayrn O’Connor, a Banner Health physician.
