Working 'off the record': Polio eradication and state immunity in Chad

The reappearance of polio in Chad generates anxieties about governance as well as public health. Since Chad was declared polio-free in 2003, at least 180 cases of paralytic polio have been linked to importations of wild poliovirus from Nigeria. In efforts to eradicate polio through houseto- house vaccination campaigns, international agencies have aggressively implicated political leaders, placing those authorities in a bind. On the one hand, governments are required to demonstrate compliance in the form of universal vaccination. On the other hand, the legitimacy of political leaders and of local authorities in particular depends upon their ability to show compassion for their populations and to be responsive to individual circumstances and concerns about the drops. This article looks at how the obligation of the African state to adopt global public health policy as its own becomes problematic when the goals and protocols of international agencies rely on the assumption that the state controls its population. Under pressure to render account to international agencies, state officials deploy high-level politicians to enforce vaccination mandates at critical moments, create administrative forms to record campaign progress that conceal difficulties in vaccinating children, and use statistics to portray the campaigns as success stories. Local authorities, who feel the bind most acutely, grant exceptions to the mandate of universal vaccination to certain subjects and work with local vaccinators and supervisors to keep cases of unvaccinated children 'off the record'. These efforts allow the vaccination campaigns to be carried out without incident even as they work against the goal of polio eradication.
