COVID-19 Vaccine Linked to Fewer Infections and Allergic Conditions in children with Eczema

Children diagnosed with atopic dermatitis (AD), more commonly known as eczema, could face fewer infections and allergic problems after receiving the COVID-19 vaccine, according to new research presented at the 2025 American College of Allergy, Asthma and immunology (ACAAI) Annual Scientific Meeting in Orlando.
“Atopic dermatitis is a chronic skin condition driven by the immune system and often precedes the growth of asthma and allergic rhinitis,” explained medical student Tristan Nguyen, BS, the lead author of the study. “Children with AD are also at higher risk for infections, including those affecting the skin and respiratory system.”
Large study Examines Vaccinated vs. Unvaccinated Children
Researchers performed a retrospective cohort study that included 5,758 vaccinated and 5,758 unvaccinated children under the age of 17 who had atopic dermatitis. Participants in both groups where carefully matched for demographic and health characteristics to ensure balanced comparison. Children who had previously been infected with COVID-19 or had serious underlying medical conditions were not included in the study.
“Our study suggests that COVID-19 vaccination not only protects against coronavirus but may also have broader health benefits for children with atopic dermatitis,” said principal investigator Zhibo Yang, MD, PhD.”We found lower rates of both allergic conditions and infections among vaccinated children compared to thier unvaccinated peers.”
Fewer Infections and Allergic Conditions Among Vaccinated Children
The analysis revealed several key trends:
- Vaccinated children had notably fewer infections, including otitis media, pneumonia, bronchitis, bronchiolitis, sinusitis, upper respiratory infections, impetigo, molluscum contagiosum, and other common skin infections.
- They were also less likely to develop allergic conditions such as asthma, allergic rhinitis, contact dermatitis, and food-triggered anaphylaxis.
- There was a longer time between vaccination and the onset of several illnesses, including allergic rhinitis, viral infections, and ear infections.
Possible Role in Preventing Disease Progression
“The results indicate that vaccination may help reduce the likelihood of atopic disease progression, such as the development of asthma, in children with eczema,” said Dr. Yang. “It reinforces the safety and potential added benefits of COVID-19 vaccination in this vulnerable population.”
