Our analysis yields a cost-benefit rule for eradication, which we apply to the current initiative to eradicate polio. If the pathologies in question were tuberculosis or polio, we would not be claiming much success on the basis of the results of these campaigns. But polio eradication is more complicated than that. This suggests that the transmission of polio from vaccine recipients t o their contacts is not extensive. Although the smallpox virus is much larger than polio, the technical feasibility of artificially synthesizing smallpox is perhaps dubious. We find that polio eradication would be economically desirable - provided, that is, that eradiation of this disease were technically feasible. We derive a cost-benefit rule for optimal eradication, and demonstrate its utility by applying it to the current global initiative to eradicate polio. This program has made vaccines against common childhood infections such as measles and polio available to countries where local governmental resources simply cannot do so. Investigators also arranged for stool specimen collection and shipment to the national polio laboratory network for poliovirus detection and identification. We note that money spent on polio eradication has an opportunity cost. Our analysis is unable to determine whether health outcomes would improve if the money spent on polio eradication was spent instead on other health interventions. Given this decision, rich countries will not benefit substantially from polio eradication. To know whether polio eradication is optimal, we need to ask if conditions like (21) and (23) hold for polio. It is likely that this type of vaccine will assume a greater prominence in the future as the worldwide eradication of polio approaches. These examples are from corpora and from sources on the web.
