Vaccination campaigns rely on the political authority of the state to carry out public health programs for the benefit of its citizens. In sub-Saharan Africa where vaccination programs were introduced by health officials during colonial rule, subsequent postcolonial programs, such as interventions which focus on a single disease and are supported mainly by western international NGOs, may be viewed with suspicion by some. Rather than strengthening state control of its citizens, vaccination campaigns such as the Global Polio Eradication Initiative as implemented in northern Nigeria, may undermine state authority and control. With its initial focus on polio vaccination rather than on childhood diseases which parents considered more life-threatening, the initiative highlighted the federal government’s failure to provide basic primary health care. That the GPEI was funded by western international NGOs also led some Muslim parents, religious leaders, and medical professionals to question the safety of the oral polio vaccine and to refuse vaccination for their children. However, in 2013 their actions have been tempered by programs providing monetary awards to state governments and foodstuffs to cooperating mothers and in September 2015, WHO announced the interruption of wild poliovirus in Nigeria.
