Abstract

Public health budget constraints force policy makers to prioritize resources toward those interventions that yield the highest perceived benefits. Intuitively, it appears optimal to focus resources on affordable interventions against prevalent diseases. However, due to the dynamics of infectious disease eradication, policies focusing on a static perception of priorities may lead to economically suboptimal outcomes. Using a hypothetical two-disease dynamic transmission model, we explore several different decision rules with respect to vaccination policy for eradicable diseases. The simulations show that cost-effectiveness decreases as the extent of priority shifting increases. This model suggests the need for a longer-term dynamic perspective to appropriately recognize costs and benefits of different policies for eradicable diseases.
