Résumé     In Australia, annual vaccination with trivalent influenza vaccine (TIV) is recommended for healthcare providers. Each year, an influenza vaccination program is run in south metropolitan area hospitals in Perth, Western Australia. In 2010, a survey to examine side effects following vaccination and subsequent significant respiratory illnesses during the influenza season was undertaken. A total of 2245 individuals vaccinated in the area-wide hospital vaccination program responded, representing 50% of consenting recipients. Data linkage was performed to ascertain additional information such as brand details. Side effects within 48h of receipt of the influenza vaccine were reported by 387 (17.2%). Only 30 respondents (1.3%) had to seek health advice following a side effect temporally related to influenza vaccination and 10 (0.4%) required treatment. Recipients who received Fluvax(®) (364, 18.0%; CSL Biotherapies) were more likely to report side effects than those who received another brand (23, 10.2%; OR 1.94, 95% CI 1.24-3.03, P=0.004). The difference in the side effect profiles was largely confined to systemic effects. Most respondents (1621, 72.2%) did not require time off work for a respiratory illness during the subsequent influenza season. Overall, the influenza vaccine was demonstrated to be safe among this large sample of predominantly healthcare workers. A higher rate of adverse events, albeit primarily mild, was reported among recipients of Fluvax(®) in 2010.
