We review published economic evaluations of influenza vaccination for children, including direct individual benefits and indirect societal benefits, to determine whether more studies are needed to fully understand the expected benefits of such strategies. ⋯ Most published evidence points to an economic interest for society of vaccinating children against influenza. However, differences in study design hinder the comparison of the various vaccination strategies considered. Comparable and complete data on the burden and cost of disease, and the cost of vaccination are needed, especially outside of North America.
