Conduct of vaccination in hard-to-reach areas to address potential polio reservoir areas, 2014–2015

Abstract

BackgroundThe Global Vaccine Action Plan (GVAP) seeks to achieve the total realization of its vision through equitable access to immunization as well as utilizing the immunization systems for delivery of other primary healthcare programs. The inequities in accessing hard-to-reach areas have very serious implications for the prevention and control of vaccine-preventable diseases, especially the polio eradication initiative.The Government of Nigeria implemented vaccination in hard-to-reach communities with support from the World Health Organization (WHO) to address the issues of health inequities in the hard-to-reach communities. This paper documents the process of conducting integrated mobile vaccination in these hard-to-reach areas and the impact on immunization outcomes.MethodsWe conducted vaccination using mobile health teams in 2311 hard-to-reach settlements in four states at risk of sustaining polio transmission in Nigeria from July 2014 to September 2015.ResultsThe oral polio vaccine (OPV)3 coverage among children under 1 year of age improved from 23% at baseline to 61% and OPV coverage among children aged 1–5 years increased from 60 to 90%, while pentavalent vaccine (penta3) coverage increased from 22 to 55%. Vitamin A was administered to 78% of the target population and 9% of children that attended the session were provided with treatment for malaria.ConclusionsThe hard-to-reach project has improved population immunity against polio, as well as other routine vaccinations and delivery of child health survival interventions in the hard-to-reach and underserved communities.

Every Child on the Map: A Theory of Change Framework for Improving Childhood Immunization Coverage and Equity Using Geospatial Data and Technologies

“…Mobile technologies and cellular networks provide opportunities to improve data collection, transfer, analysis, and use [41]. The combination of near real-time communication with automatic collection of accurate location data enables field-based teams of vaccinators to report on the number and location of doses delivered and any barriers encountered during immunization campaigns into an integrated dashboard where managers can monitor progress and respond appropriately to challenges and missed communities [42][43][44][45]. These daily reports of progress during campaign activities can help inform the next day's strategy or provide evidence to extend or alter activities to reach all children in the target area [43][44][45].…”

The relationship between armed conflict and reproductive, maternal, newborn and child health and nutrition status and services in northeastern Nigeria: a mixed-methods case study

“…The first example of an alternative means of health service delivery is one of procedure. Considering the results of the HeRAMS, which showed widespread destruction of fixed health facilities with a resulting major loss of access, mobile "hard-to-reach" (HTR) teams were developed throughout northern Nigeria in 2015, initiated by the polio eradication program [30]. For the humanitarian response, an HTR-MNCH project was initiated, with trained health care workers traveling to accessible but underserved areas for short periods of time.…”

Vaccinations and Vaccinators’ Tracking System in Island Settlements: CHAD 2017-2018

“…Users are able to identify which areas were visited and understand the coverage at the settlement, health area and health district levels. It serves as a monitoring and accountability tool 21 ensuring that vaccinators make actual visits and missed settlements easily identified.…”
