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.
