Section snippets
Methods
The study was conducted among HCW of the Hospital Clínic of Barcelona (HCB), a public university hospital with 700 beds. Before the campaign, during the first 2 weeks of September 2010, HCW were recruited and surveyed.

HCW were recruited by sequentially searching a list of 480 HCW compiled by randomizing a list of all HCW. The aim was to recruit 420 subjects from a total of 5,258 HCW,
Development of the program
The materials used in the campaign were developed according to 2 main messages, which are summarized in Box 1, Box 2:
Four promotional videos were shot using HCB HCW as the main characters.14 The videos were shown on strategically placed screens and on the Internet. Two posters15 were designed sequentially and were placed in 2 steps in all wards and hospital entrances. We also designed brochures15 with information on the transmission of influenza, the vaccine, and the risk groups. An adapted

Campaigns in the HCB17 are
