Urticaria is a common cutaneous adverse event from coronavirus disease 2019 vaccination. Previous studies hypothesized that excipients as polyethylene glycol in BNT162b2 vaccine and polysorbate in ChAdOx1 nCoV-19 vaccine are allergens. A 28-year-old woman had urticaria after a booster vaccination with BNT162b2 at the site of previous intradermal injection with severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) spike protein. This reaction emphasized that delayed urticaria may not be an allergic reaction to excipient but rather to the immunogen as such as SARS-CoV-2 spike protein.
荨麻疹是2019冠状病毒病疫苗接种常见的皮肤不良事件。既往研究推测,BNT162b2疫苗中的聚乙二醇以及ChAdOx1 nCoV-19疫苗中的聚山梨酯等辅料为变应原。一名28岁女性在之前皮内注射严重急性呼吸综合征冠状病毒2(SARS-CoV-2)刺突蛋白的部位接种一剂BNT162b2加强针后出现荨麻疹。该反应强调,迟发性荨麻疹可能并非对辅料的过敏反应,而是对诸如SARS-CoV-2刺突蛋白这类免疫原的过敏反应。
