Companies help Tanzania to ensure its remote clinics are amply stocked

NAIROBI, Kenya - Tanzania is set to launch the world's largest drone delivery network in January, with drones parachuting blood and medicines out of the skies to save the lives of women giving birth and children struck by malaria, in a country larger than Nigeria.

California's Zipline will make 2,000 deliveries a day to more than 1,000 health facilities across the East African country, including blood, vaccines and malaria and AIDS drugs, following the success of a smaller project in nearby Rwanda.
