Abstract
IntroductionDuring the influenza vaccination campaign 2011–2012 we established a self-declaration system of adverse events (AEs) in healthcare workers (HCW). The aim of this study is to describe the vaccinated population and analyse vaccination coverage and self-declared AEs after the voluntary flu vaccination in a university hospital in Barcelona. MethodsObservational study. We used the HCW immunisation record to calculate the vaccination coverage. We collected AEs using a voluntary, anonymous, self-administered survey during the 2011–2012 flu vaccination campaign. We performed a logistic regression model to determine the associated factors to declare AEs. ResultsThe influenza vaccination coverage in HCW was 30.5% (n=1507/4944). We received completed surveys from 358 vaccinated HCW (23.8% of all vaccinated). We registered AEs in 186 respondents to the survey (52.0% of all respondents). Of these, 75.3% (n=140) reported local symptoms after the flu vaccination, 9.7% (n=18) reported systemic symptoms and 15.1% (n=28) both local and systemic symptoms. No serious AEs were self-reported. Female sex and aged under 35 were both factors associated with declaring AEs. ConclusionsOur self-reporting system did not register serious AEs in HCW, resulting in an opportunity to improve HCW trust in flu vaccination.
