Because of reports of allergic reactions in some people who have received a COVID-19 vaccination, the Centers for Disease Control this week issued new guidelines on managing such risks. But the precautions and contraindications don’t include people who have most common allergies.
Neither the Pfizer nor the Moderna vaccine is thought to prevent a heightened risk for people allergic to foods (including eggs and gelatin), latex, pet dander, pollen, insect bites and other environmental factors or to oral medication. The warnings do, however, specify a 30-minute observation period (rather than the standard 15 minutes) for anyone who has a history of anaphylaxis due to any cause.
The agency recommends no vaccination only for those who have had an allergic reaction to a previous mRNA COVID vaccine or to the common food and drug additives polyethylene glycol (PEG) or polysorbate.
In between those two categories, people who have had an allergic reaction to another type of vaccine or injected medication are urged to consult with a medical professional about possible risk. If they go ahead with the vaccine, they should be observed for 30 minutes afterward for signs of reaction, the guidelines say.
