How Experience Shapes Health Beliefs: The Case of Influenza Vaccination

This study examines the impact of past experience with influenza and the influenza vaccine on four categories of the Health Belief Model: beliefs about susceptibility to contracting influenza, severity of illness, perceived benefits of the vaccine in preventing influenza, and perceived barriers to getting vaccinated. The study population comprised employees at different workplaces in Israel. The results indicate that individuals who took flu shots in the past perceived higher levels of benefits from the vaccine and lower barriers to getting the vaccine than those who had not been vaccinated. In addition, those who had influenza over the last 2 years exhibited higher levels of perceived susceptibility and lower levels of perceived benefits from the vaccine. These results imply that an individual's health beliefs regarding the flu vaccine can be changed as a result of accumulated experience with the illness and the vaccine. Therefore, recommendations for first-time vaccination may have implications on decisions to be vaccinated over the long run.
