American scientists have discovered an unexpected positive effect of the COVID-19 vaccine for children with atopic dermatitis. The results of the study were presented at the annual conference of the American College of Allergy, Asthma and Immunology (ACAAI-2025) in Orlando.
The study found that vaccinated children with atopic dermatitis were less likely to suffer from other infectious and allergic diseases compared to those who were not vaccinated. Atopic dermatitis is a chronic inflammatory skin disease that often precedes the development of asthma or allergic rhinitis, and also increases the risk of respiratory and skin infections.
The study included more than 11,500 children under the age of 17. Half had received the COVID-19 vaccine and half had not. The researchers excluded children with severe underlying medical conditions or previous coronavirus infection.
The results showed that vaccinated children had fewer cases of bronchitis, otitis media, pneumonia, skin infections, and upper respiratory tract infections. The risk of asthma, contact dermatitis, allergic rhinitis, and food anaphylaxis was also reduced.
Study leader Dr. Zhibo Yang noted that COVID-19 vaccination not only strengthens immunity, but can also reduce the risk of progression of atopic and allergic diseases in children with eczema, improving their quality of life.
These findings highlight the importance of vaccination not only as protection against COVID-19, but also as additional support for the immune system of children prone to allergies and infections.
