Vaccination Coverage of Children with Epidermolysis Bullosa Against Vaccine Preventable Diseases According to National Preventive Vaccination Programmes: Cross-Sectional Study

Abstract

Background. Patients with epidermolysis bullosa (EB) have higher risk of developing infectious diseases. Its prevention requires timely vaccination. For now, there are no studies showing vaccination coverage for this category of children. Objective. Our aim was to study vaccination coverage of children with EB according to national preventive vaccination programmes. Methods. This retrospective cross-sectional study examined medical records of patients with EB from Russian Federation and neighbouring countries. Vaccination coverage (completeness and timeliness) and age of immunization initiation were analyzed. Moreover, we have studied the spectrum of early post-vaccine reactions and the course of the post-vaccine period in children with EB vaccinated for the first time. Results. The study included medical records of 134 patients with EB aged from 8 months to 17 years 8 months. Vaccination was performed according to national immunization programs in 37 (28%) children, only 21 cases were carried out in a timely manner. Medical exemptions were the major reason for the refusal of vaccination in most cases (82%). 48 patients with EB were vaccinated against 12 vaccine preventable diseases in the hospital. The post-vaccine period was asymptomatic in 36 (76%) patients, 10 (20%) patients had tenderness and hyperemia at the injection site, 2 (4%) patients had subfebrile fever. Conclusion. Most children with EB are still unvaccinated or vaccinated untimely. Immunization of such children against vaccine preventable disease according to the individual plan can be pretty useful.
