This is the information leaflet for the Pfizer vaccine. I looked it up because I carry an Epipen as severe allergy to wasp stings, some shellfish (unknown which) - both reactions to these would be severe facial and body swelling, thankfully some years ago. I have the flu vaccination every year with no problems, I would take the covid vaccine, from the ingredient list it would be unclear what you would be allergic to as mainly chemical ingredients. My guess is that I would probably get the Oxford vaccine as I am in group 7 of phase 1 and the Oxford vaccine will be more suitable for mass vaccinating.
