title: Immunisation rates of children with cystic fibrosis using the Australian Childhood Immunisation Register.
abstract: OBJECTIVE
  The Australian Immunisation Handbook (ninth edition) recommends children with cystic fibrosis (CF) receive routine scheduled immunisations plus annual influenza vaccine and an additional pneumococcal vaccine at both 12 months and 4-5 years. Adherence with these recommendations is unknown. This study aimed to determine the immunisation status of children with CF attending the Royal Children's Hospital (RCH), Melbourne.
  
  
  METHODS
  A retrospective audit of children with CF aged 6 months to 7 years (at 1 January 2008) was performed on the RCH CF outpatient clinic database. The Australian Childhood Immunisation Register (ACIR) and RCH Immunisation Service records were used to determine immunisation status.
  
  
  RESULTS
  Eighty-nine children with CF were identified, 52 (58%) were male, with median age of 3.6 years. Eighty-two of 89 children (92%) were up to date with routine immunisations. According to the ACIR, of the 89 children sampled, 24 (27%) were given influenza vaccine in accordance with recommendations in 2007. Eighty children were older than 12 months of age at 1 January 2008 and 17 (21%) of these children had received the additional pneumococcal vaccine at 12 months. Thirty-eight children were older than 4 years of age at 1 January 2008 and 6 (16%) received the recommended 23vPPV booster.
  
  
  CONCLUSIONS
  Most children with CF received their routine childhood immunisations but not the additional recommended immunisations. This highlights the potential value of the ACIR to accurately record all vaccines administered and for ACIR reminder letters to include the additional vaccines for children in special-risk groups.
