A potential solution to minimize disparities could be right above our heads—literally. The San Francisco-based company Zipline, founded in 2014, recently began delivering Oxford-AstraZeneca’s Covid-19 vaccine doses using autonomous drones, as part of the COVAX initiative, a project working to expedite production and equitable worldwide access to coronavirus vaccines, as well as tests and treatments. Operations have already begun in Ghana, where Zipline has four distribution centers and plans to disseminate 2.5 million doses over the next year, and are soon to start in Zipline’s other markets of the United States and Rwanda. Deliveries in Nigeria are planned for later this year.
