Good question, . I had the first Pfizer vaccine 1 week ago. I’m not sure if you’d say my allergies are off the charts, but they’re up there. I had no reaction, not even a sore arm. You might find this link interesting. It that lists the ingredients in it as well as allergy information: https://healthycanadians.gc.ca/recall-alert-rappel-avis/hc-sc/2020/74543a-eng.php. Hope this helps, and good luck. Please let us know how it goes, Cora Lyn, AtopicDermatitis.net Team Member
