For now, Zipline will make between 50 and 150 deliveries per day to 21 clinics in the western half of the country. UPS, the US delivery and logistics giant, helped ship all of Zipline's equipment to Rwanda. The UPS Foundation, the company's charitable branch, earlier this year invested 1.1 million in a project to investigate how such drone delivery could be expanded to other medicines, and other countries. And while for now the Rwanda service will just deliver blood, there are plans to expand into other medical areas, such as vaccines. Gavi, a public-private partnership which promotes vaccination, is partnering with UPS and Zipline on the research.
