With Brazil experiencing the worst yellow fever outbreak from mosquitoes in decades, Little George, Ketchum’s Brazilian creative shop, worked with scientists at Ananse to create mosquito-repelling children’s toys. We turned protection from mosquitoes into “child’s play” and developed the first mosquito repellent storybook, coloring crayons, and children’s superhero cape. We distributed the collection to remote villages and schools throughout the Amazon jungle where there’s a serious shortage of vaccines, and even topical repellents are scarce and unaffordable to families. Within the first three weeks of our visit, we earned 67,000+ media stories, generating 500 million impressions, in 30 countries. Three hundred stories on social media were viewed and shared 4.5+ million times. Distribution of the collection is now underway throughout the Amazon and in the first months there have been no reports of yellow fever and malaria outbreaks among children in these villages.
