During the pandemic, Nigeria’s National Primary Healthcare Development Agency (NPHCDA) was charged with implementing the country’s COVID-19 vaccination mandate through the coordination of mass vaccination campaigns. In 2021, low and inconsistent COVID-19 vaccination rates were observed, presenting a significant challenge for the country.
To understand why there was low vaccine uptake, NPHCDA partnered with Center for Disease Control Nigeria (CDC Nigeria). This institution conducted national studies between July and August 2021. The findings revealed a lack of confidence in vaccines and issues around access to vaccination services as major reasons.
Using this information, CDC Nigeria, with the support of African Field Epidemiology Network (AFENET) and Sydani, began helping NPHCDA in late 2021 to increase COVID-19 vaccination rates in priority states (Adamawa, Benue, Borno, Ekiti, Kwara, Niger, Osun, Plateau, and Yobe). These organisations supported NPHCDA by overseeing the collection and analysis of vaccination-related data.
Aware of GRID3’s previous support of mass COVID-19 vaccination campaign, NPHCDA began discussions with GRID3 again between November and December 2021 to determine additional ways of using geospatial data to support health workers in identifying locations where mobile vaccination stations could reach large numbers of people that might otherwise be missed.
In response, GRID3 made an openly available ‘Optimisation for COVID-19 Mass Vaccination Campaign Sites in Nigeria’ dashboard that enables users to easily visualise GRID3 data (such as population estimates, settlements, and existing health centre locations). It also visualises the placement of potential new vaccination sites (using a site placement optimisation algorithm by GRID3 partner Flowminder).
