RESUMO

INTRODUCTION: Poliomyelitis remains a global threat despite availability of oral polio vaccine (OPV), proven to reduce the burden of the paralyzing disease. In Nigeria, children continue to miss the opportunity to be fully vaccinated, owing to factors such as unmet health needs and low uptake in security-compromised and underserved communities. We describe the implementation and evaluation of several activities to create demand for polio vaccination in persistently poor-performing local government areas (LGAs). METHODS: We assessed the impact of various polio-related interventions, to measure the contribution of demand creation activities in 77 LGAs at very high risk for polio, located across 10 states in northern Nigeria. Interventions included provision of commodities along with the polio vaccine. RESULTS: There was an increasing trend in the number of children reached by different demand creation interventions. A total of 4 819 847 children were vaccinated at health camps alone. There was a reduction in the number of wards in which >10% of children were missed by supplementary immunization activities due to noncompliance with vaccination recommendations, a rise in the proportion of children who received ≥4 OPV doses, and a decrease in the proportion of children who were underimmunized or unimmunized. CONCLUSIONS: Demand creation interventions increased the uptake of polio vaccines in persistently poor-performing high-risk communities in northern Nigeria during September 2013-November 2014.

RESUMO

BACKGROUND: Remarkable progress had been made since the launch of the Global Polio Eradication Initiative in 1988. However endemic wild poliovirus transmission in Nigeria, Pakistan, and Afghanistan remains an issue of international concern. Poor microplanning has been identified as a major contributor to the high numbers of chronically missed children. METHODS: We assessed the contribution of the revised household-based microplanning process implemented in Kano State from September 2013 to April 2014 to the outcomes of subsequent polio supplemental immunization activities using used preselected planning and outcome indicators. RESULTS: There was a 38% increase in the number of settlements enumerated, a 30% reduction in the number of target households, and a 54% reduction in target children. The reported number of children vaccinated and the doses of oral polio vaccine used during subsequent polio supplemental immunization activities showed a decline. Postvaccination lot quality assurance sampling and chronically missed settlement reports also showed a progressive reduction in the number of children and settlements missed. CONCLUSIONS: We observed improvement in Kano State's performance based on the selected postcampaign performance evaluation indicators and reliability of baseline demographic estimates after the revised household-based microplanning exercise.

RESUMO

BACKGROUND: The polio eradication initiative had major setbacks in 2003 and 2007 due to media campaigns in which renowned scholars and Islamic clerics criticized polio vaccines. The World Health Organization (WHO) partnered with journalists in 2007 to form the Journalists Initiatives on Immunisation Against Polio (JAP), to develop communication initiatives aimed at highlighting polio eradication activities and the importance of immunization in northern Nigeria. METHODS: We evaluated the impact of JAP activities in Kaduna State by determining the total number of media materials produced and the number of newspaper clips and bulletins published in support of polio eradication. We also determined the number of households in noncompliant communities that became compliant with vaccination during 2015 supplementary immunization activities (SIAs) after JAP interventions and compared caregivers' sources of information about SIAs in 2007 before and after the JAP was formed. RESULTS: Since creation of the JAP, >500 reports have been published and aired, with most portraying polio vaccine positively. During June 2015 SIAs in high-risk wards of Kaduna STATE, JAP interventions resulted in vaccination of 5122 of 5991 children (85.5%) from noncompliant households. During early 2007, the number of caregivers who had heard about SIA rounds from the media increased from 26% in January, before the JAP was formed, to 33% in March, after the initiation of JAP activities. CONCLUSIONS: The formation of the JAP resulted in measurable improvement in the acceptance of polio vaccine in northern Nigeria.

RESUMO

INTRODUCTION: One of the major challenges being faced in the Global Polio Eradication Initiative program is persistent refusal of oral polio vaccine (OPV) and harassment of vaccination team members by youths. The objective of the study was to describe the strategy of collaborating with recognized youth groups to reduce team harassment during vaccination campaigns and improve vaccination coverage in noncompliant communities. METHODS: We assessed data from polio vaccination activities in OPV-refusing communities in the Igabi and Zaria local government areas (LGAs) of Kaduna State in Nigeria. We evaluated the following factors to determine trends: enhanced independent monitoring data on the proportion of children missed by vaccination activities (hereafter, "missed children"), lot quality assurance surveys, and vaccination team harassment. RESULTS: The proportion of missed children decreased in both LGAs after the intervention. In Igabi LGA and Zaria LGA, the lowest proportions of missed children before and after the intervention decreased from 7% to 2% and from 5% to 1%, respectively. Lot quality assurance survey trends showed an improvement in immunization coverage 1 year after youth groups' engagement in both LGAs. CONCLUSIONS: Systematic engagement of youth groups has a great future in polio interruption as we approach the endgame strategy for polio eradication. It promises to be a veritable innovation in reaching chronically missed children in OPV-refusing communities.
