Mast cells partly contribute to allergic enteritis development: Findings in two different mast cell‐deficient mice

PEGylated form of PEG) is not a contraindication for receiving the COVID19 mRNA vaccines.8 The role of excipient ST prior to COVID19 vaccination appears limited.8,9 Patients in our study largely tolerated COVID19 vaccination despite paclitaxel or docetaxel HSR, and there is no identified role to date for the use of skin testing to PEG/polysorbate 80 prior to COVID19 vaccination in these patients.8
