Deliveries by drone are making progress around the world. More so than here in the US for now, but hopefully, that will change soon. In the island-nation of Vanuatu, vaccines were delivered by drone this week. Many of the villages spread out over the various islands are so hard to reach that about 20% of the children miss their shots. Drones have shown to be a viable solution to this problem, making Vanuatu the first nation in the world with a childhood vaccine program that is officially drone-dependent.
