Rwandan President Paul Kagame launched the world’s first national drone delivery service during a ceremony in the country’s centrally located Muhanga District. Starting today, the Rwandan government will begin using drones to make up to 150 on-demand, emergency deliveries per day of life-saving blood to 21 transfusing facilities located in the western half of the country.

The drones and delivery service are built and operated by Zipline, a California-based robotics company. While Rwanda’s drone delivery service will initially focus on blood, an international partnership between UPS, Gavi, the Vaccine Alliance, and Zipline will help the country quickly expand the types of medicines and lifesaving vaccines that can be delivered.

“Drones are very useful, both commercially and for improving services in the health sector. We are happy to be launching this innovative technology and to continue working with partners to develop it further,” said Rwandan President Paul Kagame.
