“…The Nigerian government, in collaboration with partners, launched a large-scale coordinated response to the outbreak ( 3 ). This report describes progress in polio eradication activities in Nigeria during January–December 2017 and updates previous reports ( 3 – 5 ). No WPV cases have been reported in Nigeria since September 2016; the latest case had onset of paralysis on August 21, 2016 ( 3 ).…”

“…The commitment of both countries to eradicate it and stop its spread is clear, given the time that has now elapsed since the last reported cases of Polio. For example, in Nigeria only six WPV cases were reported in the first nine months of 2014 as compared with 49 reported cases during the same period in 2013 18 .…”

“…In 2012, the World Health Assembly endorsed the Global Vaccine Action Plan, which includes an aim of ensuring delivery of universal access to immunization with associated targets of reaching 90% national vaccination coverage and at least 80% vaccination coverage in every district [2]. To support this goal and to respond to the 2012 World Health Assembly’s declaration of polio eradication as a public health emergency, Nigeria is working to achieve polio-free status [3], and continues to strengthen routine immunization (RI) service delivery to achieve high and equitable coverage [4]. …”

BackgroundDespite recent success towards controlling poliovirus transmission, Nigeria has struggled to achieve uniformly high routine vaccination coverage. A lack of reliable vaccination coverage data at the operational level makes it challenging to target program improvement. To reliably estimate vaccination coverage, we conducted district-level vaccine coverage surveys using a pre-existing infrastructure of polio technical staff in northern Nigeria.MethodsHousehold-level cluster surveys were conducted in 40 polio high risk districts of Nigeria during 2014–2015. Global positioning system technology and intensive supervision by a pool of qualified technical staff were used to ensure high survey quality. Vaccination status of children aged 12–23 months was documented based on vaccination card or caretaker’s recall. District-level coverage estimates were calculated using survey methods.ResultsData from 7,815 children across 40 districts were analyzed. District-level coverage with the third dose of diphtheria-pertussis-tetanus vaccine (DPT3) ranged widely from 1–63%, with all districts having DPT3 coverage below the target of 80%. Median coverage across all districts for each of eight vaccine doses (1 Bacille Calmette-Guérin dose, 3 DPT doses, 3 oral poliovirus vaccine doses, and 1 measles vaccine dose) was <50%. DPT3 coverage by survey was substantially lower (range: 28%–139%) than the 2013 administrative coverage reported among children aged <12 months. Common reported reasons for non-vaccination included lack of knowledge about vaccines and vaccination services (50%) and factors related to access to routine immunization services (15%).ConclusionsSurvey results highlighted vaccine coverage gaps that were systematically underestimated by administrative reporting across 40 polio high risk districts in northern Nigeria. Given the limitations of administrative coverage data, our approach to conducting quality district-level coverage surveys and providing data to assess and remediate issues contributing to poor vaccination coverage could serve as an example in countries with sub-optimal vaccination coverage, similar to Nigeria.
