    OBJECTIVES: Influenza vaccination in children with rheumatic diseases is oftenrecommended, but not frequently performed. Our aim was to assess the safety and efficacy of annual influenza vaccination ... in a longitudinal follow-up study of an unselected group of children with juvenile idiopathic arthritis (JIA). METHODS: Thirty-one children with stable JIA (10 boys, 21 girls, mean age 11.0 years) receiving various therapies and 14 children in a control group (10 boys, 4 girls, mean age 11.9 years) were vaccinated with theannual influenza vaccine BegrivacŽ 2008/2009. The children in both groups were followed for adverse events and infections 6 months after vaccination. Autoantibodies production and antibody titers against three vaccine viruses were determined in serial samples taken before, 1 and 6 months after vaccination. RESULTS: Eleven (35%) children with JIA and 5 (36%) children in the control group reported short-term adverse events. A JIA flare was observedone month after vaccination in 4 (13%) patients, and in the following five months in 7 (23%) patients. The response to vaccination after one month was significant in the control and study groups as a whole, but not in a subgroup of 4 children receiving anti-TNF-Ž therapy. After six months, no significant differences in the protective titers against vaccine viruses amongthe patient and control groups were observed. Changes in the mean values of autoantibodies after vaccination were found only for IgG aCL in the JIA group. CONCLUSIONS: No long-term adverse events were reported after influenzavaccination in JIA and control group. Thirty-five percent of childrenwith JIA experienced flare of the disease after vaccination. Protective antibodies against at least 2 vaccine viruses 6 months after vaccination were detected in all patients.
