A European net-monetary benefit analysis of influenza vaccination in the workplace

Abstract

Influenza is a major worldwide cause of morbidity and mortality, affecting 5-30% of the population per year, and is also a major cause of workplace absenteeism. This net-benefit analysis assesses the costs and cost-savings of a workplace influenza vaccination programme across eight European countries. A decision-analysis model was developed that examined the net benefit of workplace influenza vaccination. The employer perspective was taken, which considered reduction in time off work as the primary endpoint. This study found that vaccinating employees against influenza can produce significant cost-savings for firms. The net saving increased when the attack rate or wage rate was higher, when the duration of absence from work was longer, or when more people took time off work. Workplace vaccination was found to be cost-saving across the majority of European countries evaluated. In conclusion, a more structured approach towards influenza prevention for the working population in Europe is warranted. © 2005 T&F Informa UK Ltd.
