French healthcare workers in geriatric healthcare settings staunchly opposed to influenza vaccination: The VESTA study

The observational diagnosis phase of the VESTA study was aimed to determine the composite profiles of vaccinated/non-vaccinated HCWs by analyzing reasons to accept/decline influenza vaccination. Between June and September 2005, 2485 HCWs (female: 82.9%; nursing auxiliaries: 42.1%; vaccination coverage: 23.4%) from 53 French geriatric HCSs were included in the study. Cluster analysis determined 3 composite profiles: HCWs for whom information programs on vaccination can be useful (59%), HCWs staunchly opposed to vaccination (36%), and skeptical HCWs (5%). Qualitative analysis provided some aspects of influenza vaccine reluctance. Effective programs would be multidimensional and target the most susceptible group. © 2010 Elsevier Ltd.
