Chronic urticaria: not only after COVID-19 vaccination

Area of Science:

• Immunology
• Dermatology
• Public Health

Background:

• Chronic urticaria (CU) is a荨麻疹 condition characterized by recurrent hives.
• Vaccination is a critical public health intervention.
• The relationship between vaccines and urticaria requires ongoing investigation.

Purpose of the Study:

• To review current literature on the association between vaccination and the onset of chronic urticaria.
• To assess the potential role of vaccines, including COVID-19 vaccines, in triggering or exacerbating CU.

Main Methods:

• Literature review of studies examining vaccine administration and subsequent urticaria development.
• Analysis of recent findings from large-scale SARS-CoV-2 vaccination campaigns.

Main Results:

• Large-scale COVID-19 vaccination campaigns have indicated a link between vaccines and the onset or exacerbation of chronic urticaria.
• Evidence suggests COVID-19 vaccines may act as triggers for chronic spontaneous urticaria (CSU).

Conclusions:

• COVID-19 vaccines may play a role in the development of CSU.
• Further research is needed to determine the role of other vaccines in CU.
• Educating patients with vaccine-induced CU is crucial to address vaccine hesitancy.
