There are logistical differences between distributing vaccines to heavily populated urban centers and poorer outlying areas. These differences require attention to ensure equitable distribution of the COVID-19 vaccine. Vaccinating rural communities, which are the most vulnerable to COVID-19, requires special attention. 

The Geographic Information System (GIS) is a tool for vaccinating rural communities to ensure equitable distribution. This system of maps allows civic authorities to access a comprehensive source of data and translate it into actionable information on the optimal places for setting up relief operations of any kind.

Information on socioeconomic conditions combined with an overlay of physical terrain provides the tools for determining who is most in need of immunization. This ensures that vaccine site planners make the most of a decentralized distribution plan when deciding how to provide for rural areas efficiently.

What Is It?

It is best to view GIS as a method of overlapping different types of data on a given location so that an interested party can view it in light of whatever context they might need. GIS users can filter out whatever data they do not find relevant to their task.

National Geographic adds that the system operates through entering relevant information such as topography and housing distribution in a process called “data capture.” This stores information in snapshots that can inform viewers of how recent their data is and illustrate changes through certain date ranges.

These data stem from multiple sources, involving images from an aerial scan and/or records of human activity. So, the value of GIS in vaccinating rural communities stems from the clear picture it offers distributors on where they can have the most impact. Pandemic frontline workers can make informed decisions wherever they are by pulling up relevant data from their maps on areas of interest.

Who Does It Help?

GIS, with its ability to keep people up-to-date on the condition of areas in need, provides the means to supplement efforts with additional pre-planning. Aside from working around the capacity of available healthcare centers by choosing areas with sufficient personnel and space for vaccinating rural communities, there are more benefits of GIS. These include:

1. Once GIS creates fairness in planning for nationwide immunity, its information on demographics helps at managing vaccine distribution by relative need based on their vulnerability to COVID-19. On a broad scale, this can mean selecting a cluster of people based on relatively low access to healthcare or a high concentration of infirmities. On a smaller scale, this might involve isolating demographic groups such as the homeless or discriminated minorities.
2. Keeping track of vaccine stockpiles becomes more important when a larger distribution range requires storing vaccines closer to rural areas. In cases where a country is using vaccines that require two doses, timely delivery is crucial. By storing vaccines in the countryside, distributors find a median between shortening the logistical tail and allowing for the distance necessary for reaching impoverished areas without such hospitals.

Who Is Using GIS?

South Africa quickly adopted GIS as a means of vaccinating rural communities in situations where income gaps between different municipalities impacted travel times to the nearest hospital.

“Reaching South Africans in remote places has begun using mobile teams and mobile pharmacies to ensure that the vaccination program covers ‘the last mile,’” writes Luis Monzon on work the South African government did with volunteers from health NGO Right to Care. Right To Care’s mobile pharmacies regularly use their access to digital maps for tasks as routine as locating the optimal route to their destinations.

An earlier success story is that of Nigeria’s experience using GIS in its efforts to eradicate polio when it was discovered that hand-drawn maps did not accurately reflect resources on the ground. This realization and the use of geospatial data served as the basis for fine-tuning the Nigerian government’s strategy. In having the foundation for a distribution strategy before receiving 16 million doses of Oxford-AstraZeneca’s vaccine, government projections indicate a 40% immunization rate by the end of 2021.

Equal Opportunity Efficiency

Widespread adoption of GIS ensures that a country’s disaster response strategy can protect even the most remote areas from the destabilizing influence of a national crisis. Future applications of this technology likewise stand to benefit as its pool of experienced users broadens.

Whether the responsibility of vaccinating rural communities is in response to a national health crisis or other disruption to normalcy, GIS ensures the fastest possible response in mitigating the impact of a disaster. Expanding access to such comprehensive data serves as a further step in building a self-sufficient network for disaster-preparedness beyond the scope of a pandemic.
