New Insights on Cause of Rare Anaphylaxis Following COVID-19 Vaccination

New Insights on Cause of Rare Anaphylaxis Following COVID-19 Vaccination

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. Further cases of suspected anaphylaxis to the Pfizer vaccine were subsequently reported. This was alarming, as anaphylaxis to vaccines is rare; in the order of 1 case per million doses, and therefore likely to injure public confidence.

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.

The authors note that very few people are allergic to PEG, and they provide a guide to identifying those who are at risk. “This preliminary report confirms PEG as a cause of anaphylaxis to the Pfizer/BioNTech vaccine, for the first time,” they wrote. “COVID-19 vaccine anaphylaxis and PEG allergy are both rare, so proof of PEG as the cause in one case of vaccine anaphylaxis is important. However, it is important to emphasise that PEG allergy is rare and that COVID-19 vaccines remain safe.”

Polyethylene glycol (PEG) is a cause of anaphylaxis to the Pfizer/BioNTech mRNA COVID‐19 vaccine. Clinical & Experimental Allergy, 6 April 2021.
