Following reports of patients experiencing severe allergic reactions after receiving the COVID-19 vaccine, the Centers for Disease Control and Prevention (CDC) has updated its guidance concerning��patients with��allergies,�����Ի���allergic reactions to the vaccines.��

Even people with a history of severe allergic reactions��not��related to vaccines or injectable medications (including food, pet, venom, environmental, or latex allergies), should be vaccinated,����say,��as should those with “a history of allergies to oral medications or a family history of severe allergic reactions.”��

Considerations Before Receiving the Vaccine

The vast majority of people—even those��with a history of allergies—can receive the vaccine safely, says��infectious disease expert Kristen Marks, MD,��associate professor of medicine-Weill Cornell Medical College, Cornell University.��

“Until we have more information, those with a history of a severe allergic reaction like anaphylaxis to any vaccine to any vaccine or injectable medicine should be cautious about getting the vaccine,” Dr. Marks explains. “If that applies to you, discuss with your provider to decide how to proceed.”

Possible Allergic Reactions to Vaccine Ingredient

��advised that patients who are allergic to a substance called polyethylene glycol (PEG),��or a related substance called polysorbate,��not��get the COVID-19 vaccine:��“Polysorbate is not an ingredient in either mRNA COVID-19 vaccine but is closely related to PEG, which is in the vaccines.”��

In addition, the��CDC��recommends that providers observe��all patients should be observed for 15 to 30 minutes after they receive the vaccine, and��have emergency medicines and equipment��on hand��to��rapidly manage��allergic��reactions.��

If a patient experiences��an allergic reaction to the vaccine,��the provider��will send a report to the����(VAERS), a national system that compiles reports about vaccine reactions from healthcare professionals, vaccine manufacturers, and the public.��
