title: Awareness of vaccination status and its predictors among working people in Switzerland.
abstract: BACKGROUND
  Adult vaccination status may be difficult to obtain, often requiring providers to rely on individual patient recall. To determine vaccination status awareness and the sociodemographic predictors of awareness for tetanus, hepatitis A and B, tick born encephalitis (TBE) and influenza vaccination.
  
  
  METHODS
  Multivariate analyses were used to evaluate a questionnaire survey of 10,321 employees (4070 women and 6251 men aged 15-72 years) of two companies in Switzerland.
  
  
  RESULTS
  Among 10,321 respondents, 75.5% reported knowing their tetanus vaccination status, 64.1% hepatitis A, 61.1% hepatitis B, 64.3% TBE and 71.9% influenza. Between 1 in 4 and 1 in 3 employees were not aware of their vaccination status. Differences in awareness for the five vaccinations considered correlated with gender and language. These differences persisted in multivariate analyses.
  
  
  CONCLUSIONS
  Women employees, German-speaking employees and employees who paid more attention to their diet were more often aware of their vaccination status. A more reliable and readily accessible data source for vaccination status is needed in order to capitalize on opportunities to update vaccinations among Swiss employees.
