We aimed to evaluate the acceptance of pandemic influenza A 2009 vaccination in our high risk children with chronic renal diseases. A total of 64 children/parents of pediatric nephrology department were approached to fill in a standardised questionnaire on influenza immunization profile. The H1N1 vaccination rates were 57.1% for transplant recipients, 61.5% for patients on peritoneal dialysis (PD), 36.4% for patients with various stages of chronic renal disease (CRD) and 26.7% for patients with glomerulonephritis (GN) on immunosuppressive therapy. Children on renal transplantation or PD had a fourfold higher rate of being vaccinated than children with GN (p=0.04). Causes of denying vaccination included fear of adverse effects (48.9%), lack of sufficient data on the new vaccine (31.9%) and others (19.2%). Patients being vaccinated were all urged by their pediatric nephrologist (100%), while patients not vaccinated were negatively influenced by media (41.4%), friends (24.1%), pediatrician (20.7%) and others (13.8%). Regarding parents education, higher level was associated with increased rate of children vaccination (p=0.04). It seems that patients with severe renal disease had better compliance with vaccination. The pediatric nephrologists had the most significant positive influence in contrast to the media which had the most negative influence.
