Health-economic modelling is useful for assessing the clinical requirements and impact of new vaccines. In this study, we estimate the impact of potential vaccination for respiratory syncytial virus (RSV) of infants in the Netherlands. A decision analysis model was employed using seasonal data from a cohort of children (1996-1997 through 1999-2000) to assess hospitalisation, costs and impact of vaccination. Yearly, an estimated 3670 infants are hospitalised with RSV-infection in the Netherlands, vaccination protecting infants from 3 months of life onwards could prevent approximately 1000-3000 hospitalisations, depending on the effectiveness of the potential vaccine. Additionally, vaccination could prevent a major share of RSV-related costs. Comparison of the calculated break-even prices with the average price of recently introduced vaccines indicates that pricing for a potential RSV-vaccine most likely allows for only a single dose vaccination or several doses at a relatively low price per dose in order to achieve cost savings. However, if evidence on relevant RSV-related mortality would become available, higher pricing would be justified, while still remaining below accepted thresholds for cost-effectiveness.
