Abstract
The mechanisms underpinning allergic reactions to the BNT162b2 (Pfizer) COVID-19 vaccine remain unknown, with polyethylene glycol (PEG) contained in the lipid nanoparticle suspected as being the cause.Our aim was to evaluate the performance of skin testing and basophil activation testing to PEG, polysorbate 80, and the BNT162b2 (Pfizer) and AZD1222 (AstraZeneca) COVID-19 vaccines in patients with a history of PEG allergy.Three known individuals...
