SUMMARY: To determine the vaccination rate and its adverse reactions after influenza vaccination, we administered an anonymous questionnaire survey during the last three influenza seasons from 2005-2006 to 2007-2008. In total, the rate of Influenza vaccination was 82.3% in health-care personnel. Dividing the subjects into four groups by work category, the vaccine coverage rates were as follows: physicians 67.9%; nurses and nursing assistants 91.2%; technicians, pharmacists, therapists, and administrative personnel 80.2%; and other personnel not directly involved in patient care but having the potential of being exposed to infectious agents 89%. The most frequent adverse reaction after vaccination was soreness at the injection site in 33.4%, followed by skin redness in 18.1%, myalgia in 17.7%, fatigue in 17%, and febrile sensation in 15.2%. After vaccination, such adverse reactions began within 24 h in 70.6% of subjects. Eighty-nine percent of those adverse reactions persisted for 1-3 days, but 11% persisted more than 4 days. Serious adverse reactions were not noted; the reported adverse reactions were relatively minor and transient. Surprisingly, among those who were vaccinated, the physicians’participation was the lowest. We believe that influenza vaccination is safe and that physicians should be more concerned with influenza vaccination and its impact on the health-care community.
