Countries get creative with inoculation campaigns 

With several effective vaccines approved, governments around the world are now tasked with managing the unprecedented rollout to inoculate populations from the coronavirus. The immense effort has led to some creativity in making the jab accessible. In London, taxis are being converted into Vaxi Taxis to transport people to vaccination sites. And officials in Ghana are using small drones to fly vaccines and parachute the supplies down to remote medical clinics.
