Abstract: The most effective method of preventing influenza infection and complications is through vaccination. However, annual vaccination rates remain low. This study examines the impact of influenza vaccination on healthcare utilisation among the elderly population in Catalonia, Spain. Indeed, we examine the impact of vaccination on various outcomes related to direct and indirect health costs. Utilising longitudinal data on healthcare resource utilisation for individuals born before 1965 in Catalonia, we used instrumental variables for vaccination shots based on previous flu campaign incidence individually and outbreaks in the area of residence. The results showed a significant (beneficial) impact of vaccination on using influenza-related healthcare (count of visits and health direct costs) and sick leave duration. However, no effects were observed on influenza-related mortality.
