The coronavirus vaccine is already being distributed in the United States, and so far, there have been very few issues reported. Out of hundreds of thousands of vaccinations, a small number of recipients have experienced allergic reactions, which nevertheless has some people worried about their chances of a similar response. But there’s little cause for concern, unless you’re allergic to one specific ingredient. According to experts, if you’re allergic to polyethylene glycol, you should wait to get the COVID vaccine. Read on to find out why people with this allergy may want to hold off, and for more on vaccination preparedness, If You Have This Common Condition, Tell Your Doctor Before the Vaccine.
On Dec. 14, the American College of Allergy, Asthma and Immunology (ACAAI) COVID-19 Vaccine Task Force issued guidance on the Pfizer vaccine, which had been authorized by the U.S. Food and Drug Administration (FDA) three days prior. In their guidance, the organization pointed out one specific ingredient that may cause problems for those with a history of allergies to it.
“The Pfizer-BioNTech COVID-19 vaccine should not be administered to individuals with a known history of a severe allergic reaction to polyethylene glycol (PEG), as it is a component of this vaccine that is known to cause anaphylaxis,” the ACAAI warned.
Moderna’s vaccine, which wasn’t authorized by the FDA until Dec. 18, also contains this ingredient. So those with a PEG allergy may need to hold off on both vaccines until more research is conducted.
The Centers for Disease Control and Prevention (CDC) echoes this concern, but without specifically calling out PEG. In its guidance, the CDC says that the Pfizer and Moderna vaccine should not be given to anyone with a history of severe allergic reactions to any ingredient used in the vaccines.
According to Science Magazine, “some allergists and immunologists believe a small number of people previously exposed to PEG may have high levels of antibodies against PEG, putting them at risk of an anaphylactic reaction to the vaccine.”
A 2016 study published in Analytical Chemistry found that as many as 72 percent of people have at least some antibodies against PEG, and about 7 percent have levels high enough that they could be at risk of an anaphylactic reaction. That having been said, as Science Magazine notes, allergic reaction to the COVID vaccines have only been documented in eight people.
Nevertheless, an allergic response to PEG is not out of the question. According to the author of the Analytical Chemistry study, Samuel Lai, PhD, a pharmaco-engineer at the University of North Carolina Chapel Hill, people presumably develop these antibodies as a result of exposure to cosmetics and pharmaceuticals that contain PEG.
