From: An economic analysis of poliovirus risk management policy options for 2013–2052
Expected, undiscounted vaccination costs in 2013 United States dollars ($) for the main policy options based on 100 stochastic iterations of the global poliovirus transmission model. (a) Assuming OPV restart without SIAs if more than 50,000 cumulative cases occur after 2016). (b) Assuming OPV restart with SIAs if more than 50,000 cumulative cases occur after 2016. (c) Including only iterations without OPV restart. See Table 1 for policy abbreviations.
