BackgroundEvidence-based recommendations for vaccination of patients with pediatric rheumatic diseases (PRDs) are available, their implementation in practice is unknown.ObjectivesTo analyze real-life vaccination coverage in children with PRDs and identify reasons for incomplete vaccination.MethodsUp-to-date information on vaccination status of Slovak children followed at a tertiary pediatric rheumatology center was retrieved from pediatricians over an 18-month period and compared to the standard Slovak Immunization Schedule. Reasons for missed vaccinations were analyzed retrospectively.ResultsVaccination records of 156 patients (median age 10 years, 2–18) with PRDs (JIA n = 108, systemic diseases n = 21, autoinflammatory diseases n = 16, uveitis n = 9, others n = 2) were available for analysis. 117 (75.0%) were completely vaccinated, 2 (1.3%) had not received any vaccine due to reasons unrelated to PRD. 37 (23.7%) remaining patients missed altogether 48 mandatory vaccinations. In 58.3% (n = 28, in 24 patients) no PRD related reasons for missing vaccinations were identified. Only 20 vaccinations (18 live-attenuated and 2 non-live in 19 patients) were missed due to ongoing immunosuppressive treatment or PRD activity. Patients aged 11–14 years were more likely to be incompletely vaccinated than other age groups (48.8% vs. 15.9%, p < 0.001), mainly due to missed MMR booster. Systemic immunosuppressive treatment was a significant predictor for incomplete vaccination status (OR 5.03, 95% CI 1.13–22.31, p = 0.03).ConclusionFull vaccination is possible in a high proportion of PRD patients. In addition to immunosuppressive therapy, reasons unrelated to PRDs are a frequent and possibly inadequate cause of missed vaccinations. Periodic vaccination status assessments are needed in pediatric rheumatology care.
