Economic impact of influenza vaccination in preschool children

Objective. The economic impact of routine vaccination of preschool children with inactivated influenza vaccine was investigated. Design. A decision analysis was performed using data from the literature. D irect and indirect costs of each vaccination strategy were calculated and c ompared with a strategy of not vaccinating. Setting. Two settings were evaluated: a setting in which vaccination was av ailable during flexible hours and a setting in which vaccination was availa ble only during usual work hours (8:00 am-5:00 pm). Results. Vaccination resulted in a net cost savings in both settings. The n et savings per vaccine recipient were $21.28 in the flexible setting and $1 .20 in the restricted setting. Although the analysis was performed for the inactivated vaccine, sensitivity analysis showed that the nasal vaccine cou ld also result in a net cost savings depending on the price of the cold-ada pted vaccine when it is licensed. Conclusion. Vaccinating preschool children is economically advantageous. Se rious consideration should be given to recommending vaccination in this age group.
