Chicken egg allergy and vaccination: Modern approaches

Introduction The study examined how people with chicken egg allergies react to vaccines that contain egg-derived components. Aim The purpose of the study was to determine the reaction of an organism with hypersensitivity to a chicken egg to immunisation of the body with drugs that contain this allergen. Material and methods To achieve this goal, vaccines against measles, mumps, rubella, influenza, chickenpox, rabies, and yellow fever were analysed. Results and discussion It was determined that these patients did not have an allergic reaction, since the finished vaccines have minimal remnants of chicken egg elements that cannot cause hypersensitivity, but it is worth noting that such vaccination should be carried out in a hospital setting. Immunisation against diseases such as influenza and chickenpox is a safe method of disease prevention. After vaccination against measles, mumps, and rubella, only 2 of them after the procedure had clinical signs of developing allergies, in the form of lacrimation, sneezing, and allergic rhinitis, which was 3.5%. Rabies, yellow fever, and chickenpox vaccines can cause allergies, so an alternative vaccination should be used in this case. It was determined that hypersensitivity of the body to chicken eggs is not a contraindication to vaccination against measles, mumps, rubella, influenza. Conclusions Immunisation of the body is safe, even in the case of a previous anaphylactic complication in contact with an allergen in humans, because the finished preparation contains only the remains of a chicken egg, which are not able to cause a full-fledged allergic reaction.
