New insights on cause of anaphylaxis following COVID-19 vaccination

(Wiley) On the first day of the UK campaign for COVID-19 vaccination, there were reports of two cases of anaphylaxis — a severe, potentially life-threatening allergic reaction — within minutes of administration of the Pfizer/BioNTech mRNA vaccine. Subsequently further cases of suspected anaphylaxis to the Pfizer vaccine were reported. A new report published in Clinical& Experimental Allergy reveals that an allergy to the ingredient polyethylene glycol (PEG) is a cause of anaphylaxis to the vaccine. However, this is in the context of millions of doses safely administered.
