Pandemic cost, net benefits and return on investment.
Pandemic cost is the total cost associated with the health outcomes of influenza cases and the cost of vaccination. Net benefits are the difference in cost due to improved health outcomes from vaccination and the vaccination cost. Return on investment is the gain in net benefits relative to the vaccination cost, that is, dollars saved per $1 investment in vaccine intervention.
