Inclusion criteria

Inclusion criteria: 1. The study population consisted of all staff at a single teaching hospital (approximately 15,000 staff) in the UK. 2. Over the 6 months that the study ran (October 2011 to March 2012) a total of 464 staff followed a hyperlink in a Occupational Health Services (OHS) fortnightly e-bulletin and bimonthly e-newsletter, randomly allocating them to one of three conditions. OHS also advertised the research study (‘a study of views on influenza vaccination’) and included a hyperlink to participate in the study. 3. After removing individuals who had entered the site more than once or who had failed to leave sufficient personal details for them to be identified in order to be able to ascertain their influenza vaccination behavior from records, there was a total of 269 cases. 4. The sample had a mean age of 43 years and was predominantly female (209), married with children, white British and had some patient contact. Just over half supervised others, were health professionals and had been vaccinated for influenza in the previous year. The three test conditions did not differ by age (p = .61), gender (p = .15), marital status (p = .63), ethnicity (p = .14), children (p = .14), patient contact (p = .14), supervision of others (p = .75), being health professionals (p = .85) or past vaccination (p = .19), indicating the success of randomization.
