Allergies et vaccins

Atopy and the onset of an allergic reaction during vaccination sometimes result in abstention that disadvantages the patient. First, the problem of vaccinating the atopic individual is discussed with the recurrent problem of egg allergy. Only severe anaphylaxis to egg requires hospitalization for vaccines containing egg protein. Asthma exacerbation reactions or atopic dermatitis (flash phenomenon) require certain precautions before vaccination. Apart from these measures, there is no systematic vaccine contraindication for the atopic child and the French vaccination schedule can be applied to children with allergies. After reviewing the components of vaccines that have an allergic potential, we discuss the course to follow in cases of reaction to a vaccine.
