Factors affecting influenza vaccine uptake among health care workers at the Medical and Health Sciences Center of Debrecen University, Hungary]

Influenza vaccination is the most effective way of influenza prevention. The vaccination rate is low worldwide. In Hungary, the vaccine is free of charge to health care workers and, therefore, the low vaccination rate is unaccountable.In this study, the authors wanted to explore those factors which influence the refusal of vaccination.The Health Science Center of Debrecen University has about 4000 employees. The authors adjusted a questionnaire with 45 questions and sent it to 525 randomly selected health care workers, 294 of whom responded (response rate, 56%). The Epiinfo software was used for statistical evaluation.The respondents strongly agreed that the vaccine is free and easy to obtain at the workplace. Official recommendations of the occupational health, the Medical Association of Hungary and advice of the family doctors failed to influence the decision. However, a significant impact of communication with family members, friends and colleagues on the decision was documented.The results indicate that the most important tool in decision making of influenza vaccination is the internal communication, but this effect is not a permanent one. International data show highly variable vaccination rates (between 2.1% and 82%). A better vaccination rate (98% or above) may be achieved with a mandatory influenza vaccination program among health care workers.
