Chronic urticaria: not only after COVID-19 vaccination

Purpose of review To resume the current literature about vaccination and the onset of chronic urticaria. Recent findings The recent large-scale vaccination against SARS-CoV-2 targeting elderly, adult and children, has highlighted how vaccines can trigger onset or exacerbation of chronic urticaria. Summary COVID-19 vaccines may act as triggers in the development of chronic spontaneous urticaria. More data regarding the other vaccines are necessary to evaluate a similar potential role. Proper education of patients with vaccine-induced chronic urticaria is essential to avoid vaccination hesitancy.
