If you have ever had a severe allergic reaction to any ingredient in a COVID-19 vaccine, the CDC recommends that you should not get that vaccine. You can find the ingredients and more information on the Pfizer-BioNTech COVID-19 vaccine
and the Moderna COVID-19 vaccine
on the U.S. Food and Drug Administration (FDA) website
If you have had a severe allergic reaction to other vaccines or injectable therapies, ask your doctor if you should get a COVID-19 vaccine. Your doctor will help you decide if it is safe for you to get vaccinated.
People with a history of severe allergic reactions not related to vaccines or injectable medications — such as allergies to food, pets, venom, environments or latex — may still get vaccinated.
People with a history of allergies to oral medications or a family history of severe allergic reactions, or who might have a milder allergy to vaccines (without anaphylaxis) — may also still get vaccinated.
