You should not get the COVID-19 vaccine:

• If you have had a severe allergic reaction (anaphylaxis) or an immediate allergic reaction (within 4 hours – includes hives, swelling, wheezing) – to any ingredient in a COVID-19 vaccine
• If you have an allergy to polysorbate 80, do not take the J&J vaccine; discuss with your medical provider if you should receive Pfizer or Moderna instead
• If you have an allergy to polyethylene glycol (PEG), do not take Pfizer or Moderna vaccines, you may receive the J&J vaccine

If you have had a severe allergic reaction (anaphylaxis) or an immediate allergic reaction after getting the first dose of the vaccine, you should not get a second dose of either of the mRNA COVID-19 vaccines.

An allergic reaction is considered severe when a person needs to be treated with epinephrine or EpiPen© or if they must go to the hospital. Learn about common side effects of COVID-19 vaccines and when to call a doctor.

Children and adolescents outside these authorized age groups should not receive COVID-19 vaccination at this time.
