“No One is Safe, Unless Everyone is Safe”—Reaching Zero-Dose Children with Reveal

By Anabelle Nuelle on April 28, 2021 in COVID-19, GIS, News

Maximal coverage defines the effectiveness of vaccination campaigns. Over one year after the start of the devastating COVID-19 pandemic, countries around the globe are vaccinating those ages 16 and older, while vaccine-producing companies are conducting vaccine trials for children. Positivity and hope infuse vaccine distribution efforts, but as these initiatives ensue, attention is being drawn to the challenges of vaccine distribution, namely, those left behind. 

Mass vaccination campaigns are critical to the introduction of new vaccines, to providing doses to those who may have missed routine doses, and to giving a second opportunity to those who may not have developed immunity. In each instance, with greater coverage comes stronger, more resilient communities. However, zero-dose children, or children who have not received any routine vaccinations, are often missed by these campaigns. With every child left unvaccinated, communities’ vulnerability to vaccine-preventable diseases escalates. Fortunately, in bracing for future vaccination efforts, we can look to previous initiatives to guide our efforts. In particular, the potential of geospatial data and technology to ensure all, including zero-dose children, are included. 

From June through to December 2020, Akros, in partnership with Johns Hopkins University, Macha Research Trust, and the Zambia Ministry of Health, utilized spatial intelligence and the Reveal platform to identify and vaccinate zero-dose children following a nationwide Zambian vaccination campaign for measles and rubella. 

Grand Challenges Explorations Grant Enables Further Reveal Development

We are thrilled to announce Akros has been awarded a Grand Challenges Explorations Grant, an initiative of the Bill & Melinda Gates Foundation! Grand Challenges Explorations (GCE) grants support impactful innovations striving to remedy critical global health and development problems. With this grant, Akros will incorporate into Reveal the ability to integrate data from human movement models. Reveal is a web-based mapping platform which uses spatial intelligence to ensure all receive life-saving interventions. With the ability to integrate human movement models with Reveal, decision makers and field teams will be better able to predict where people will be at different times of the day and seasons to ensure no one is missed with lifesaving resources. 

The existing Reveal Platform, improves health campaign coverage by utilizing spatial intelligence and context-appropriate technology. Presently, Reveal maps communities at the household level and offers intervention teams a streamlined interface to plan, implement, track and monitor campaign coverage. Relative to traditional approaches in which local health teams aggregate population data by hand and process it in hard copy, Reveal’s user-centered technology offers a more accurate population count and implementation system—designed to include even the most remote of households.

Delivering health campaigns at high coverage rates can be challenging—particularly in places where frequent movement is common. Permanent relocation may swell or shrink a population, influencing critical resource distribution. Seasonal migration may redistribute a population for months at a time. Daily or weekly movements may make certain individuals more likely to be left out of a campaign. In these situations, health workers may arrive at a household to deliver interventions, but instead find the family has shifted, for even just a few months depending on fishing or farming needs. Take for instance, Nchelenge District in Northern Zambia.
