标题：Supplementary report: surveillance of adverse events following immunisation among children aged less than 7 years in Australia, 1 January to 30 June 2005
摘要：This report summarises national passive surveil-lance data contained in the Adverse Drug Reactions Advisory Committee (ADRAC) database at 30 Sep-tember 2005 for adverse events following immuni-sation (AEFI) reported for children aged <7 years who received vaccines between 1 January and 30 June 2005.1–3The average annual population-based AEFI reporting rates were calculated using mid-2004 population estimates. Reporting rates per 100,000 doses of vaccine were calculated for eight vaccines that are funded by the National Immunisa-tion Program (NIP) using denominator data from the Australian Childhood Immunisation Register (ACIR). The report includes data for adverse events following receipt of the seven-valent pneumococcal conjugate vaccine (7vPCV), which has been funded under the NIP from 1 January 2005 for all infants at two, four and six months of age, with a catch-up program for children born from 1 January 2003.4AEFI reporting rates were not estimated for some vaccines due to lack of reliable denominator data
