Does Penicillin Allergy Affect Covid Vaccine?

Yes you can. Allergy to penicillins is not a contraindication to the Pfizer/BioNTech, AstraZeneca, Moderna or Janssen COVID-19 vaccine.

What is the ingredient in the COVID-19 vaccine that people are allergic to?

PEG is an ingredient in the mRNA vaccines, and polysorbate is an ingredient in the J&J/Janssen vaccine. If you are allergic to PEG, you should not get an mRNA COVID-19 vaccine.

Can the Moderna COVID-19 vaccine cause allergic reactions?

There is a remote chance that the Moderna COVID-19 Vaccine could cause a severe allergic
reaction. A severe allergic reaction would usually occur within a few minutes to one hour after
getting a dose of the Moderna COVID-19 Vaccine. For this reason, your vaccination provider
may ask you to stay at the place where you received your vaccine for monitoring after
vaccination. Signs of a severe allergic reaction can include:
• Difficulty breathing
• Swelling of your face and throat
• A fast heartbeat
• A bad rash all over your body
• Dizziness and weakness
