Factors affecting immunization rate in a cohort of elderly veterans: a retrospective pilot study of influenza vaccine compliance.

A survey of aged veterans greater than or equal to 85 years old was undertaken to determine their vaccination behaviour prior to mounting a local education campaign on influenza vaccine. A questionnaire inquiring into circumstances which may have influenced their decision to be immunized against influenza was mailed to all 300 elderly veterans (greater than or equal to 85) obtained from the register at the James A. Haley Veterans' Hospital. Ninety-two persons responded in self addressed stamped envelopes and data were analysed six months following mailing date. The most important reason for not being immunized was lack of information concerning vaccine recommendations and its availability (48%). Fear of 'shots' and side effects was the next most important reason for not taking the vaccine (19%). Amotivation and transportation difficulties played comparatively minimal roles (10%, 13%). These data suggest that health education measures may improve vaccine compliance in the elderly population who suffer from higher death rates and complications from influenza.
