Urticaria, angioedema events account for 13% of COVID-19 vaccine reactions

Urticaria and/or angioedema events comprised 13% of the adverse reports from clinicians after mRNA vaccinations for COVID-19, according to a presentation at the American Academy of Allergy, Asthma & Immunology Annual Meeting. Noting that hypersensitivity reactions were reported after mass COVID-19 vaccination events were implemented, evidence-based information about side effects can combat vaccine hesitancy, the researchers said.
