Course: Incidence of Cutaneous Reactions After Messenger RNA COVID-19 Vaccines
CME Credits: 1.00
Released: 2021-06-23
Mucocutaneous reactions, such as pruritus, urticaria, and angioedema, may occur after COVID-19 messenger RNA (mRNA) vaccination. To our knowledge, the incidence of these reactions and recurrence with subsequent vaccination has not been described. Cutaneous reactions may contribute to unnecessary avoidance of future vaccination doses.
We prospectively studied Mass General Brigham employees who received an mRNA COVID-19 vaccine (first dose: December 16, 2020, to January 20, 2021; follow-up through February 26, 2021; eMethods in the Supplement). Institutional review board approval was provided by the Mass General Brigham human research committee with a waiver of informed consent. For 3 days after vaccination, employees completed daily symptom surveys through a multipronged approach, including email, text message, phone, and smartphone application links. Cutaneous reactions included rash or itching (other than the injection site), hives, and/or swelling of the lips, tongue, eyes, or face (eAppendix in the Supplement).
