The BNT162b2 vaccine, but not PEG alone, induced dose-dependent activation of all patients' basophils exvivo. Similar basophil activation could be induced by PEGylated liposomal doxorubicin, suggesting that PEGylated lipids within nanoparticles, but not PEG in its native state, are able to efficiently induce degranulation. Our findings implicate PEG, as covalently modified and arranged on the vaccine lipid nanoparticle, as a potential trigger of anaphylaxis in response to BNT162b2, and highlight shortcomings of current skin testing protocol
