Moving medicine between Vanuatu’s 80 mountainous islands is a logistical nightmare. Getting from one island to the next is already hard enough, and nurses often have to slog through the muddy hills with a vaccine carrier on their shoulders to bring medicine to families. But that’s all starting to change after UNICEF initiated a project in which drones are sent out to deliver medicine to remote parts of the island. The drones, with an 8-foot wingspan, can carry five pounds of vaccines, ice packs, and a monitor that ensures that the vaccines stay in the narrow temperature range necessary for it to work. Best of all, the drones can endure rain and gusts when they fly, ensuring the medicine arrives safely. Currently, the drone project is in a trial phase, but if it proves effective, it could be used in other remote regions around the world.
