About this study

The goal of this clinical trial is to evaluate the humoral immunogenicity of the meningococcal B vaccine (MenB-4C) in pediatric patients with autoimmune rheumatic diseases (ARDs), compared to age- and sex-matched non-immunosuppressed controls. The main questions it aims to answer are: * To assess the influence of treatment on the response to the MenB-4C vaccine in patients with ARDs; * To evaluate the impact of the MenB-4C vaccine on disease activity in patients with ARDs; * To evaluate the safety of the MenB-4C vaccine in pediatric patients with ARDs and controls. * To evaluate the association between physical activity levels and immunogenicity after vaccination. Participants will: Receive the MenB-4C vaccine (Bexsero©), administered intramuscularly in the deltoid muscle, in a 2-dose schedule (0.5 mL each), 1 month apart. All participants will have blood samples collected immediately before vaccination at the baseline visit (D0), then receive the first vaccine dose on the same day (D0). The second dose will be administered 4 weeks after the first dose (D28). Blood samples will be collected on D0, D28, and D56. A final sample will be collected one year after the last dose (D208) to evaluate the persistence of immune response. At study entry and one month after each dose, patients will also be assessed for clinical and laboratory disease activity using disease-specific indices and scores. * Juvenile Systemic lupus erythematosus (JSLE): Systemic lupus erythematosus disea…
