Annual report: surveillance of adverse events following immunisation in Australia, 2004

This report summarises Australian passive surveillance data on adverse events following immunisation (AEFI) for 2004 and describes reporting trends over the five years, 2000 to 2004. AEFIs are notified to the Adverse Drug Reactions Advisory Committee by state and territory health departments, hospitals, doctors and other health providers, vaccine manufactures, and the public. There were 975 AEFI records for vaccines received in 2004. This is an annual AEFI reporting rate of 4.8 per 100,000 population, the lowest since 2000, and a 33 per cent decrease compared with 2003 (1,460 records; 7.1 AEFI records per 100,000 population). Dose-based AEFI reporting rates in 2004 were 1.8 per 100,000 doses of influenza vaccine for adults aged > or = 18 years and 11.8 per 100,000 doses of scheduled vaccines for children aged < 7 years. The majority of records described non-serious events while nine per cent (n = 88) described AEFIs defined as 'serious'. There were no reports of death related to immunisation. The most frequently reported individual AEFI was injection site reaction in children following a fifth dose of an acellular pertussis-containing vaccine (67 reports per 100,000 doses). The marked reduction in the AEFI reporting rate in 2004 coincided with the removal of the fourth dose of acellular pertussis vaccine, due at 18 months of age, from the vaccination schedule in September 2003 and fewer people receiving meningococcal C vaccine through the national catch-up vaccination program for those aged 1-19 years in 2004, compared with 2003. The consistently low reporting rate of serious AEFIs demonstrates the high level of safety of vaccines in Australia.     

Annual report: Surveillance of adverse events following immunisation in Australia, 2005

This report summarises Australian passive surveillance data for adverse events following immunisation (AEFI) reported to the Adverse Drug Reactions Advisory Committee for 2005, and describes reporting trends over the six year period 2000 to 2005. There were 839 AEFI records for vaccines received in 2005. This is an annual AEFI reporting rate of 4.1 per 100,000 population, the lowest since 2000 and a 22 per cent decrease compared with 2004 (1,081 records; 5.4 AEFI records per 100,000 population). The decrease was not consistent across age groups. Reporting of AEFI increased for children aged <1 year in 2005 (60.7 versus 50.3 per 100,000 population) and decreased for the 7 to <20 year age group (0.9 versus 8.9 per 100,000 population). Dose-based AEFI reporting rates in 2005 were 11.0 per 100,000 doses of scheduled vaccines for children aged <7 years and 2.0 per 100,000 doses of influenza vaccine for adults aged >18 years. The majority of records described non-serious events while 9 per cent (n=72) described AEFIs defined as serious. There was one report of death in an older person following influenza vaccine and one of non-polio acute flaccid paralysis in an infant, both temporally associated with immunisation. The most frequently reported individual AEFI was injection site reaction in children following a fifth dose of diphtheria-tetanus-acellular pertussis vaccine (79 reports per 100,000 doses). The increase in the population-based AEFI reporting rate for children aged <1 year in 2005 coincided with the introduction of national immunisation programs for conjugate pneumococcal vaccine in January 2005 and inactivated poliovirus vaccine in November 2005. The fall in reporting rates for older children and adolescents follows the completion of the national meningococcal C catch-up program in early 2005. The consistently low reporting rate of serious AEFIs demonstrates the high level of safety of vaccines in Australia.     

Annual report on surveillance of adverse events following immunisation in Australia, 2006

This report summarises Australian passive surveillance data for adverse events following immunisation (AEFI) reported to the Adverse Drug Reactions Advisory Committee for 2006, and describes reporting trends over the seven-year period 2000 to 2006. There were 779 AEFI records for vaccines administered in 2006. This is an annual AEFI reporting rate of 3.8 per 100,000 population, the lowest since 2002 and a 10% decrease compared with 2005 (869 AEFI records; 4.3 records per 100,000 population). Dose-based AEFI reporting rates in 2006 were 1.9 per 100,000 doses of influenza vaccine for adults aged > or = 18 years, 19.1 per 100,000 doses of pneumococcal polysaccharide vaccine for those aged > or = 65 years and 12.5 per 100,000 doses of scheduled vaccines for children aged < 7 years. Trend data showed transient increases in reporting of AEFI following the introduction of DTPa-IPV combination vaccines in November 2005 for children aged < 7 years. The majority of the 779 AEFI records for 2006 described non-serious events while 11% (n = 85) described AEFIs defined as serious. There was one report of death temporally associated with receipt of dTpa-IPV and typhoid vaccines in an adult with a history of a chronic medical condition. The most frequently reported individual AEFI was injection site reaction in children following a fourth or fifth dose of acellular pertussis-containing vaccine (70 reports per 100,000 doses). The data confirm the low rate of AEFI reported in Australia and demonstrate the ability of the system to detect and investigate signals such as those associated with changes in immunisation programs.     

Annual report: surveillance of adverse events following immunisation in Australia, 2009

This report summarises Australian passive surveillance data for adverse events following immunisation (AEFI) reported to the Therapeutic Goods Administration (TGA) for 2009, and describes reporting trends over the 10-year period 2000 to 2009. There were 2,396 AEFI records for vaccines administered in 2009, the highest number reported, a 46% increase over the 1,638 in 2008. The increase was almost entirely due to reports related to the introduction of pandemic H1N1 (pH1N1) 2009 influenza vaccine from September 2009 (n = 1,312) largely from the members of the public. The pH1N1 AEFI reporting rate for people aged > or = 18 years was 34.2 per 100,000 administered doses compared with 2.8 for seasonal influenza vaccine. The rates in > or = 65 year-olds were 28.0, 1.6 and 13.3 for pH1N1, seasonal influenza and polysaccharide pneumococcal, respectively. The high reporting rate for pH1N1 vaccine is likely to be at least partly due to enhanced reporting seen for all new vaccines and greater levels of reporting from members of the public in response to the implementation of strategies to encourage reporting, as part of the pH1N1 program. For children < 7 years, AEFI reporting rates in 2009 (14.1 per 100,000 administered doses) were similar to previous years. There were 193 (8%) AEFI reports classified as serious; 6 deaths temporally associated with immunisation were reported but none were judged to have a causal association. As in previous years, the most commonly reported reactions were allergic reaction, injection site reaction, fever, headache, malaise, nausea and myalgia. The most commonly reported reactions following pH1N1 influenza vaccine were allergic reaction (n = 381), headache (n = 289), fever (n = 235), pain (n = 186), nausea (n = 180) and injection site reaction (n = 178). The data within the limitation of passive surveillance provide a reference point for ongoing reporting of trends in AEFI by age group, severity and vaccine type and illustrate the value of the national TGA database as a surveillance tool for monitoring AEFI nationally.     

Surveillance of adverse events following immunisation: Australia 2002 to 2003.

Reports of suspected adverse events following immunisation (AEFI) are reviewed by the Adverse Drug Reactions Advisory Committee and collated in a central database. We analysed AEFI records for vaccines administered during October 2002 to December 2003, and assessed AEFI reporting trends for 2000 to 2003. AEFI reporting rates were calculated using denominator data from the Australian Childhood Immunisation Register and the annual national influenza vaccination coverage survey. A total of 1,744 AEFI records were analysed for October 2002 to December 2003. The majority described non-serious events; 9 per cent (n=149) described AEFIs defined as 'serious'. Four deaths were reported but none were causally related to immunisation. Dose-based AEFI reporting rates were 2.1 per 100,000 doses of influenza vaccine for adults aged 40 years or over and 19.8 per 100,000 doses of scheduled vaccines for children aged <7 years. The most frequently reported individual AEFI was injection site reaction in children after a fourth or fifth dose of an acellular pertussis-containing vaccine (54 and 98 reports per 100,000 doses respectively). The most frequently suspected vaccine was meningococcal C conjugate vaccine (34% of reports-mostly injection site reactions, gastrointestinal symptoms and headaches). The average annual reporting rate was 7.0 per 100,000 population, the highest to date. The increase in the AEFI reporting rate was due to a greater number of children becoming eligible to receive a fourth or fifth consecutive dose of acellular pertussis vaccine and the introduction of the meningococcal C vaccination program in January 2003 for those aged 1-19 years. The low reporting rate of serious AEFIs demonstrates the high level of safety of vaccines in Australia.
