Since 1997, the Global Polio Eradication Initiative has sponsored regular door-to-door polio immunisation campaigns in northern Nigeria. On 30 July 2015, the country was finally declared poliofree, a hard won success. At various times, polio eradication has been threatened by rumours and community tensions. For example, in 2003, local Imams, traditional leaders and politicians declared a polio campaign boycott, due to the concerns about the safety of the polio vaccine. Although the campaigns resumed in 2004, many parents continued to refuse vaccination because of the persistence of rumours of vaccine contamination, and anger about the poor state of health services for conditions other than polio. To address this, UNICEF and Nigerian Government partners piloted two interventions: (1) mobile 'health camps' to provide ambulatory care for conditions other than polio and (2) an audiovisual clip about vaccine safety and other health issues, shareable on multimedia mobile phones via Bluetooth pairing. The mobile phone survey found that Bluetooth compatible messages could rapidly spread behavioural health messages in low-literacy communities. The health camps roughly doubled polio vaccine uptake in the urban ward where it was piloted. This suggests that polio eradication would have been accelerated by improving primary health care services.
