BMJ Editorial: Vaccinating against covid-19 in people who report allergies

Editorial notes polyethylene glycol (PEG 2000) in the Pfizer-BioNTech vaccine is a known potential allergen. Oxford-AstraZeneca vaccine does not contain PEG2000 but does have polysorbate 80 which may be cross-reactive therefore evaluation by an allergy specialist may be required.
